Contributors to Paleontology science
Scientists and other personalities who had a significant influence on the
establishment of Paleontology science, famous fossil collectors, museum founders, etc.
The personalities list:
Georg Bauer, better known by the Latin version of his name Georgius Agricola, is considered the founder of geology as
His work paved the way for further systematic study of the Earth and of its rocks, minerals, and fossils.
In 1544, he published the De ortu et causis subterraneorum
in which he laid the first foundations of a physical geology, and criticized the theories of the ancients.
However, he maintained that a certain 'materia pinguis' or 'fatty matter,' set into fermentation by heat, gave birth to
fossil organic shapes
, as opposed to fossil shells having belonged to living animals.
In 1545, he followed with the De natura eorum quae effluunt e terra
in 1546 the De veteribus et novis metallis
, a comprehensive account of the discovery and occurrence of
minerals and also more commonly known as De Natura Fossilium
in 1548, the De animantibus subterraneis
; and in the two following years a
number of smaller works on the metals.
(21 May 1799 – 9 March 1847) was an English fossil collector and dealer
who became known around the world for important finds she made in Jurassic marine fossil beds in the cliffs along the English Channel at
Lyme Regis, now part of what is now called the Jurassic Coast, in the county of Dorset in Southwest England.
Her findings contributed to important changes in scientific thinking about prehistoric life and the history of the Earth.
Anning searched for fossils in the area's Blue Lias cliffs, particularly during the winter months when landslides
exposed new fossils that had to be collected quickly before they were lost to the sea.
Her discoveries included the first Ichthyosaur
skeleton correctly identified; the first two more complete Plesiosaur
found; the first pterosaur skeleton located outside Germany; and important fish fossils.
Her observations played a key role in the discovery that coprolites, known as bezoar stones at the time, were fossilised faeces.
She also discovered that belemnite fossils contained fossilised ink sacs like those of modern cephalopods.
Her discoveries inspired famous geologist (and childhood friend) Henry De la Beche to paint 'Duria Antiquior - A More Ancient Dorset' in 1830.
He sold prints to raise money for Mary, who was still struggling to make ends meet.
Duria Antiquior - complete with ichthyosaur, plesiosaur and pterosaur - is the very first pictoral representation of prehistoric life based
on fossil evidence.
Today the Natural History Museum in London showcases several of Mary Anning's spectacular finds, including her ichthyosaur, plesiosaur and pterosaur.
Much like they did two centuries ago, her fossils continue to captivate visitors from around the world.
Juan Bautista Ambrosetti
was an Argentine archaeologist and naturalist.
He was a pioneer in the study of national folklore and is considered the initiator of scientific archeology in Argentina.
He founded and fully organized the Ethnographic Museum, found prehistoric cities such as La Paya, in Salta.
In 1890 he published "Observations on the Oligocene fossil reptiles
of the Tertiary lands of the ancient Paraná"
(original name: “Observaciones sobre los reptiles fósiles oligocenos de los terrenos terciarios antiguos del Paraná” )
in the bulletin of the National Academy of Sciences of Córdoba.
In this article he described some fossils from collection of
Entre Ríos Museum in Paraná City, such as prehistoric lizard Propodinema
from late Miocene (9.0 - 6.8 million year ago)
is a synonym of Tupinambis
). Some prehistoric crocodiles of genus Oxysdonsaurus
Ambrosetti published a second article a few years later in the bulletin of the Argentinian Geographic Institute.
“Contributions to the study of Oligocene fluvial tortoises
in the old tertiary land in the Paraná”
(original name: “Contribución al estudio de las tortugas fluviales oligocenas de los terrenos terciarios antiguos del Paraná”).
In this article he described some prehistoric tortoises of Platemys
genus from collection of Parana Museum.

the zoologist, ichthyologist, Hydrobiology, economist, ecologist,
He founded the Romanian school of Hydrobiology, ichthyology and oceanology, pioneer in the field of museology, the
author of modern concepts in ecology, biosociologiei, biosphere.
He was director of the Museum of Natural History in Bucharest, where he
had an important contribution to the organization on a phylogenetic and ecological collections.
As a token of gratitude for his work in the museum since 1933, Museum of Natural History bears his name.
Some web sites or even catalogues mentioned this stamp as stamp of first paleontologist, but it is wrong.
The missleading is caused by fossil of Dinotherium giganteum
depicting on a background of the stamp.
It is there just because it is the most impressive artifact of the museum.
Georges-Louis Leclerc, Comte de Buffon
He envisioned the nature of science and understood the roles of paleontology, zoological geography, and animal psychology.
He realized both the necessity of transformism and its difficulties.
Although his cosmogony was inadequate and his theory of animal reproduction was
weak, and although he did not understand the problem of classification, he did establish the intellectual framework within which most
naturalists up to Darwin worked.
Buffon is considered the founder of evolutionary theory.
He was the first who mentioned that living species changed through time and who found some
similarities between humans and apps, rhen suggested they might have a common ancestor.
George Buffon set forth his general views on species classification in the first volume
of his "Histoire Naturelle".
Buffon objected to the so-called "artificial" classifications of Andrea Cesalpino and Carolus Linnaeus,
stating that in nature the chain of life has small gradations from one type to another and that the
discontinuous categories are all artificially constructed by mankind.
(1905-1981) was a Czech painter and book illustrator whose work played a
central role in the development of palaeontological reconstructions during a remarkable career spanning five decades.
Originally recognised only in his native Czechoslovakia, Burian's fame later spread to an international audience,
and a number of artists later attempted to emulate his style.
He is regarded by many as the most influential palaeo-artist of the modern era.
Burian was an extremely prolific artist whose works are estimated to number between 15,000 and 20,000 paintings and drawings (pen and pencil).
He illustrated over 500 books (including natural history subjects and numerous classic novels such as Robinson Crusoe, Tarzan, Plutonia)
and some 600 book covers, but it is within the fields of palaeontology and palaeoanthropology that Burian's influence has been most notable.
Since the late 1950s and early 1960s when Burian's work became known in the west through a series of large-format books released by the Artia
publishing house, numerous scholarly and popular books on prehistoric life have featured his work, either as originals or as art based
closely on them.
Burian worked in initial cooperation with university palaeontologist Josef Augusta from 1938/39 (during World War II all universities in
Czechoslovakia were closed due to the German occupation) and subsequently (following Augusta's death in 1968) with Zdenek pinar,
painting accurate and magnificent reconstructions representing all forms of prehistoric life from many parts of the globe, from the
earliest invertebrates to a vast array of fish, amphibians, reptiles, mammals and birds, as well as panoramic vistas of the landscapes in
which they lived.
Close to 500 prehistoric images were painted by him between the early 1930s and the late 1970s.
Whilst some of Burian's earliest palaeo works depicting North American species were inspired by the pioneering American palaeo-artist Charles R.
Knight (see for example, his first renditions of Stegosaurus and Brontotherium), partly because Burian lacked access to skeletal
material for such reconstructions, Burian's work was less stylised and more convincing with respect to both the subjects and their landscapes,
and soon became highly regarded amongst palaeontologists, especially in Europe.
Previous palaeo-artists had often produced speculative works reflecting 19th century views of large dinosaurs as lethargic reptiles
akin to giant lizards with sprawling limbs, but Burian convincingly painted them as active animals with parasagittal (mammal or bird-like)
limb-movement and musculature.
(1809 -1882 ) was born in Shrewsbury, Shropshire in 12 February 1809,
to a wealthy and well-connected family.
He had initially planned to study medicine at Edinburgh University but later switched to Divinity
at Cambridge encouraged a passion for natural science.
His five-year voyage on HMS Beagle established him as an eminent geologist whose observations and theories supported Charles Lyell's uniformitarian
ideas, and publication of his journal of the voyage made him famous as a popular author.
Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin investigated the
transmutation of species and conceived his theory of natural selection in 1838.
Although he discussed his ideas with several naturalists, he needed time for extensive research and his geological work had
priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay which described the same idea, prompting
immediate joint publication of both of their theories.
His 1859 book On the Origin of Species established evolutionary descent with modification as the dominant scientific
explanation of diversification in nature.
He examined human evolution and sexual selection in The Descent of Man, and Selection in Relation to Sex, followed
by The Expression of the Emotions in Man and Animals.
His research on plants was published in a series of books, and in his final book, he examined earthworms and their effect on soil.
The fact that evolution occurs became accepted by the scientific community and much of the general public in his lifetime, while his
theory of natural selection came to be widely seen as the primary explanation of the process of evolution in the 1930s, and now forms the
basis of modern evolutionary theory.
In modified form, Darwin's scientific discovery is the unifying theory of the life sciences,
providing logical explanation for the diversity of life.
In recognition of Darwin's pre-eminence, he was one of only five 19th
century UK non-royal personages to be honoured by a state funeral,
and was buried in Westminster Abbey, close to John Herschel and Isaac Newton.
Darwin's work had far-reaching impacts on the development of Paleontology,
Antropology and many other Biology and Psyology related scients.
(1914-1987), self-taught naturalist of great competence and
collaborator of of the Laboratory of Paleontology of the Institute of Evolution Sciences of Montpellier.
Already in age of 16, he discovered several prehistoric stations in small region of Malgoires around Fons.
In 1932 he found in the Eocene the mammalian levels reported in 19th
century, and discovered on
the edge of the Urgonian a higher Cretaceous utcrop not mentioned on the map,
where he collects bone fragments in which he recognizes remains of Dinosaurs.
For years, he spends many days in the field with the researchers from the laboratory and actively participate
in excavations in the Eocene at Fons, Euzet and Robiac.
Thomas Henrey Huxley
(1825-1895) was a big defender of Charles
Darwin's theory of evolution.
He received the nickname "Darwin's bulldog."
After reading Darwin's Origin of Species, Huxley reaction was: "How stupid of
me not to have thought of that."
Was a self-educated intellectual giant of the 19th century, a
pioneering genius whose influence was felt throughout the science,
education, and politics of Victorian England.
His brilliant career ranged from surgeon's apprentice to England's Privy Council, service on
10 royal commissions, and president of the Royal Society from 1881 to 1885.
His many awards included the Royal, Copley, and Darwin medals.
A man of astonishing energy and prodigious talent, Huxley had a sharp wit and a brilliant, questioning mind
(traits no doubt passed on to his grandsons, including novelist Aldous Huxley).
He invented the term "agnostic" to describe his own religious view, and the term's widespread, immediate acceptance freed
intellectual discourse from the belief-versus-disbelief straightjacket, in and out of theistic contexts.
And yet while he was never one to sacrifice principle for propriety, he vigorously defended his ideas but always treated his
opponents with respect and sometimes-astonishing courtesy.
Always a popularizer of science, he at once subscribed to Charles Darwin's theories and proved to be their most indefatigable
The role earned him the title "Darwin's bulldog", and he is best remembered today for his prominent role in defending evolution
against attacks from scientists, theists, and philosophers somewhat ironic, for Huxley's biological writings show less explicit
support for natural selection than for evolution itself.
(1743-1826) USA, was
third President of the United States, as universally recognized as a man of science.
He was recognized as a pioneer in ethnology, geography, anthropology and our subject paleontology.
Because of his wide range of knowledge, Jefferson was ahead of his time in several lines of inquiry
and advanced of contemporary scientists.
Even so, Jefferson never failed to acknowledge that in science he was "an amateur.
"One of the first glimpses of Jefferson's interest in paleontology can be found in his Notes on the State of Virginia.
It is his most impressive scientific achievement, in which he recorded his observations of flora, fauna, mountains, rivers, climate, population,
laws, politics, customs and fossils of his native state.
In Notes Jefferson, also, refuted the contentions of Count de Buffon
that the animals common to both old world and new are smaller in the new.
One of the reasons Jefferson wrote and published Notes was to refute a claim by the eminent naturalist, the Comte de Buffon, that human and animal
life in America was degenerative and therefore inferior to the life forms in Europe.
Buffon believed, Jefferson wrote in his Notes, "that nature is less active, less energetic on one side of the globe than she
is on the other."
Jefferson added with more than a hint of sarcasm, "as if both sides were not warmed by the same genial sun," and launched
into a lengthy refutation of Buffon's hypothesis with convincing evidence that animals are actually larger in America than in Europe.
The mastodon, or mammoth,was his clincher; Europe had produced no animal to match this behemoth ... his shipment of mastodon fossils to
Paris, therefore, was not entirely Enlightenment altruism; it was also a final salvo in a scientific war.
Buffon's suggestion that infant America was nature's retardate drove him to collect the ancient bones of the mammoth ...
When he received his fossils, he catalogued them carefully and precisely, as was his habit, sending them off to
Philadelphia for admiration, and to Paris for edification.
He kept a few choice specimens, however, for his Monticello museum--trophies of a sort in commemoration of his private victory in the
battle of New World versus Old. (McLaughlin, 1988) he entry room at Monticello had been turned by Jefferson into
a Natural History Museum which showed his great interest in fossils.
Perhaps Jefferson's greatest contribution to paleontology is that while President he helped to make it a respectable pursuit and was
largely responsible through the American Philosophical Society for bringing together the materials necessary for its advancement.
As the first citizen of the young nation, Jefferson's passion brought prestige and respectability to the young science.
Jean Baptiste Lamarck
(1744 - 1829), France Jean-Baptiste Pierre Antoine
de Monet, Chevalier de la Marck (1 August 1744, Bazentin, Somme - 18 December 1829), often just known
as "Lamarck", was a French soldier, naturalist, academic and an early proponent of the idea that evolution occurred and proceeded in
accordance with natural laws.
In the modern era, Lamarck is primarily remembered for a theory of inheritance of acquired characteristics, called soft
inheritance or Lamarckism.
However, his idea of soft inheritance was, perhaps, a reflection of the folk wisdom of the time, accepted by many
Lamarck's contribution to evolutionary theory consisted of the first truly cohesive theory of evolution, in which an
alchemical complexifying force drove organisms up a ladder of complexity, and a second environmental force adapted them to local
environments through use and disuse of characteristics, differentiating them from other organisms.
Lamarckism (or Lamarckian inheritance) is the idea that an organism can pass on characteristics that it acquired during its
lifetime to its offspring (also known as heritability of acquired characteristics or soft inheritance).
It is named after the French biologist Jean-Baptiste Lamarck (1744-1829), who incorporated the
action of soft inheritance into his evolutionary theories.
He is often incorrectly cited as the founder of soft inheritance, which proposes that individual efforts during the lifetime of the
organisms were the main mechanism driving species to adaptation, as they supposedly would acquire adaptive changes and pass them on to
After publication of Charles Darwin
's theory of natural selection, the importance of individual efforts in the generation of
adaptation was considerably diminished.
Later, Mendelian genetics supplanted the notion of inheritance of acquired traits, eventually leading to the development of the modern evolutionary synthesis, and
the general abandonment of the Lamarckian theory of evolution in biology.
Despite this abandonment, interest in Lamarckism has recently increased, as several studies in the field of epigenetics have
highlighted the possible inheritance of behavioral traits acquired by the previous generation.
In a wider context, soft inheritance is of use when examining the evolution of cultures and ideas, and is related to the theory of memetics.
Carl Linne/Carl Linnaeus
(1707 - 1778), was a Swedish
botanist, physician, and zoologist, who laid the foundations for the modern scheme of
binomial nomenclature uses in all biology related since, including paleontology
He is known as the father of modern taxonomy and is also considered one of the fathers of modern ecology.
Francisco Pascasio Moreno
(May 31, 1852 – November 22, 1919) was a prominent explorer and
academic in Argentina and famous collector of fossils
Already at a young age, with help of his brother and support of his farther, he established "Moreno Museum".
The museum was opened in house of his parents.
Nowadays, many fossils of Moreno Museum can be seen in "the Museum of La Plata
In 1880, Moreno went to France
, where he spoke at a meeting of the
Anthropology Society of Paris, discussing two prehistoric skulls he had
unearthed in Río Negro territory.
He believed one was from the Quaternary period, and the other had ritual deformation in a manner
similar to the skulls of the Aymara people of the Andes and Altiplano.
In 1888, he founded the La Plata Museum of Natural History
the museum can be seen on many Argentine stamps), the most important of
its kind in South America, that houses 3 million fossils and relics.

Francisco Javier Muniz
(21 December 1795 – 8 April 1871)
was an Argentine colonel, legislator, medical doctor, fossil
Muniz worked as a physician at Lujan.
Lujan was already a famous area due to the discovery of the immense ground sloth Megatherium
He developed a collection that he intended to be used to create a natural history museum.
He donated his artifacts (some sources say he was forced to donate them) to Juan Manuel de Rosas, who was a politician,
army officer and who ruled Buenos Aires Province and briefly the Argentine Confederation at this time.
Muniz stayed in contact with Charles Darwin
, with whom he exchanged some letters and articles.
It was Darwin who convinced Muniz in 1845, to send fossil of a sabertooth cat which Muniz described
and named as Muni-felus bonaerensis
, in Gaceta Mercantil (local newspaper) to Natural History Museum for
Experts of the museum ascribed the fossil to Smilodon bonaerensis species.

Charles Wilson Peale
- 1966: in "Scientists" stamps set (see on the right), MiNr. 945
- 1996: in "Mediciners" stamps set (see on the right), MiNr. 2297
was an American painter, soldier and naturalist.
He is best remembered for his portrait paintings of leading figures of the American Revolution,
as well as establishing one of the first museums Peale
had a great interest in natural history, and organized the first U.S.
scientific expedition in 1801.
These two major interests combined in his founding of what became the Philadelphia Museum,
and was later renamed the Peale Museum.
This museum is considered the first.
It housed a diverse collection of botanical, biological, and archaeological specimens.
Most notably, the museum contained a large variety of birds which Peale himself acquired,
and it was the first to display North American mastodon bones (which in Peale's time were
referred to as mammoth bones; these common names were amended by Georges Cuvier in 1800,
and his proposed usage is that employed today)
display of the "mammoth" bones entered Peale into a long standing
debate between Thomas Jefferson
and Comte de Buffon
Buffon argued that Europe was superior to the Americas biologically, which was illustrated
through the size of animals found there.
Jefferson referenced the existence of these "mammoths" (which he believed still roamed northern
regions of the continent) as evidence for a greater biodiversity in America.
Peale's display of these bones drew attention from Europe, as did his method of re-assembling large skeletal specimens in three
The museum was among the first to adopt Linnaean taxonomy.
This system drew a stark contrast between Peale's museum and his competitors who
presented their artifacts as mysterious oddities of the natural world.
The museum underwent several moves during its existence.
At various times it was located in several prominent buildings including Independence
Hall and the original home of the American Philosophical Society.
The museum would eventually fail, in large part because Peale was unsuccessful at obtaining government funding.
After his death, the museum was sold to, and split up by, showmen P. T. Barnum and Moses Kimball.
(1510–1589) was a French Huguenot potter, hydraulics engineer
and craftsman, famous for having struggled for sixteen years to imitate Chinese porcelain.
In the 19th
century, Palissy's pottery became the inspiration for Mintons Ltd's Victorian
majolica, which was exhibited at the Great Exhibition of 1851 under the name "Palissy ware".
Palissy is known for his contributions to the natural sciences, and is famous for discovering principles
of geology, hydrology and fossil
He was one of the first Europeans to enunciate the correct theory of the origin of fossils.
Palissy correctly maintained that fossils were the remains of once living organisms, and contested the
prevailing view that they had been produced by the biblical flood, or by astrological influence.
He argued that minerals, dissolving into water to form "congelative water," would precipitate and
thereby petrify once living organisms in order to create fossils.
(1868-1947) was a Romanian biologist, zoologist, speleologist and explorer of Antarctica.
Together with Grigore Antipa
, he was one of the most noted promoters of natural
sciences in Romania.
Racovita was the first Romanian to have gone on a scientific research expedition to the Antarctic,
more than 100 years ago, as well as an influential professor, scholar and researcher.
He found and described several fossils in caves he was observing, for example Ursilor Cave.
The cave was discovered in 1975.
The name of the cave originates from the numerous cave-bear fossils discovered here,
being an appropriate shelter for animals for more than 15,000 years.
They believe that the cave entrance was blocked by a fallen rock so that more than 140 bears attacked
each other because of hunger.
In September 1975, a group of amateur speleologists from "Speodava" Club explored the cave for the
first time and 5 years later it was opened for tourists.
(1826-1890), was born in Milan, Italy in 1824 and was already
as child very interested in natural science.
In 1850 he left Italy to escape the independence war in his country and came to Peru
for researches, scientific investigations and other observations; the decision for Peru was very
emotional but as well deliberate.
He was fascinated by the at this time absolutely unexplored country of the Incas.
Antonio Raimondi traveled more than 19 years in countless trips through Peru and explored the
country and the people under different aspects of science.
He investigated as well the impact of the Spanish presence on the Peruvians and their culture.
The already during his lifetime well respected scientist gathered animals, plants, insects, mineral,
stones, fossils, drew maps, painted watercolours and did much more.
A lot of his findings and discoveries are well assorted shown in the museum dedicated to him.
The main objective of the 'Museo Raimondi' is to honour this great scientist and preserve his inestimable
and irreplaceable efforts for Peru and the general science.
The museum displays the results of his unremitting work in all areas he did researches like archaeology,
botanic, geology, history, chemistry, zoology, geography and cartography and mineralogy.
Robert Falcon Scott
CVO (6 June 1868 – 29 March 1912) was a Royal Navy officer and explorer
who led two expeditions to the Antarctic regions: the Discovery
expedition of 1901–1904 and the ill-fated Terra Nova expedition of
On the first expedition, he set a new southern record by marching to latitude 82°S and discovered the
Antarctic Plateau, on which the South Pole is located.
On the second venture, Scott led a party of five which reached the South Pole on 17 January 1912, less
than five weeks after Amundsen's South Pole expedition.
Scott and his companions died on the second expedition.
When Scott and his party's bodies were discovered, 16kg of Glossopteris tree
(an extinct beech-like
tree from 250 million years ago
from Queen Maud Mountains found next to their bodies,
which they had dragged on hand sledges.
These fossils promised to Marie Stopes
to provide an evidence for Eduard Suess
's who suggested Antarctica had once been
part of an ancient super-continent named Gondwanaland (now Gondwana).
These fossils, were the first ever discovered Antarctic fossils
and proved that Antarctica had once been warm and connected to other continents as
suggested by Eduard Suess, as the same fossils found in Australia, Africa and South America, it was
like finding a missing piece of the Earth's jigsaw.
It indicated that these countries had all been part of the same prehistoric land mass.
Johan Christian Senckenberg
(1707 - 1772), was a German physician, naturalist and collector.
In 1763 he established the Senckenberg Foundation to support natural sciences.
This founded the Botanischer Garten der Johann Wolfgang Goethe-Universitat Frankfurt am Main.
His name is honoured in the Senckenberg Gesellschaft fur Naturforschung (Senckenberg Natural History Society)
which he endowed and Naturmuseum Senckenberg where many dinosaurs and other fossils are present.
(1638 - 1686), was a Danish pioneer in both anatomy and geology.
Already in 1659 he decided not to accept anything simply written in a book, instead
resolving to do research himself.
He is considered the father of geology and stratigraphy.
October 1666 two fishermen caught a huge female shark near the town of Livorno, and Ferdinando II
de' Medici, Grand Duke of Tuscany, ordered its head to be sent to Steno.
Steno dissected the head and published his findings in 1667.
He noted that the shark's teeth bore a striking resemblance to certain stony objects, found
embedded within rock formations, that his learned contemporaries were calling
glossopetrae or "tongue stones".
Ancient authorities, such as the Roman author Pliny the Elder, in his Naturalis Historiae, had
suggested that these stones fell from the sky or from the Moon.
Others were of the opinion, also following ancient authors, that fossils naturally grew in
Steno's contemporary Athanasius Kircher, for example, attributed fossils to a "lapidifying virtue
diffused through the whole body of the geocosm", considered an inherent characteristic of the
earth an Aristotelian approach.
Fabio Colonna, however, had already shown in a convincing way that glossopetrae are shark teeth, in
his treaty De glossopetris dissertatio published in 1616.
Steno added to Colonna's theory a discussion on the differences in composition between glossopetrae
and living sharks' teeth, arguing that the chemical composition of fossils could be altered
without changing their form, using the contemporary corpuscular theory of matter.
Steno's work on shark teeth led him to the question of how any solid object could come to be found
inside another solid object, such as a rock or a layer of rock.
The "solid bodies within solids" that attracted Steno's interest included not only fossils, as we would
define them today, but minerals, crystals, encrustations, veins, and even entire rock layers or strata.
He published his geologic studies in De solido intra solidum naturaliter contento dissertationis prodromus,
or Preliminary discourse to a dissertation on a solid body naturally contained within a solid in 1669.
Steno was not the first to identify fossils as being from living organisms; his contemporaries
Robert Hooke and John Ray also argued that fossils were the remains of once-living organisms.
(1831-1914) was born in London on August 20, 1831.
He was full professor of geology at the University of Vienna and at the same time a
full member of the Vienna Academy of Sciences.
His first book "Der Boden der Stadt Wien" ("The Soil of Vienna"), which dealt with the
correlation of geologic conditions and water supply, marked the beginning of his increasing
scientific recognition from that time forward.
He gradually developed views on the connection between Africa and Europe; eventually he came
to the conclusion that the Alps to the north were once at the bottom of an ocean,
of which the Mediterranean was a remnant.
While not quite correct (mostly because plate tectonics had not yet been discovered
he used the earlier geosyncline theory), this is close enough to the truth that he is credited
with postulating the earlier existence of the Tethys Ocean, which he named in 1893.
Suess postulated that as sediments filled the ocean basins the sea levels gradually rose, and
periodically there were events of rapid ocean bottom subsidence that increased the ocean's capacity and caused the regressions. This became
known as the theory of eustasy (eustacy).
His other major theory involved glossopteris fern fossils occurring in South America, Africa, and
India (as well as Antarctica, though Suess did not know this).
His explanation was that the three lands were once connected in a supercontinent, which he named Gondwanaland.
Again, this is not quite correct: Suess believed that the oceans flooded the spaces currently between those
lands, when in fact the lands drifted apart.
Still, it is so similar to what is currently believed that his naming has stuck.
Alfred Russel Wallace
(1823-1913) was a British naturalist, explorer, geographer, anthropologist and
He is best known for independently proposing a theory of evolution due to natural selection
Charles Darwin to publish his own theory.
Wallace did extensive fieldwork, first in the Amazon River basin and then in the Malay Archipelago,
where he identified the Wallace Line that divides the Indonesian archipelago into two distinct parts,
one in which animals closely related to those of Australia are common, and one in which the species are
largely of Asian origin.
He was considered the 19th
century's leading expert on the geographical distribution of
animal species and is sometimes called the "father of biogeography".
Wallace was one of the leading evolutionary thinkers of the 19th
century and made a number
of other contributions to the development of evolutionary theory besides being co-discoverer of
These included the concept of warning colouration in animals, and the Wallace effect, a hypothesis on
how natural selection could contribute to speciation by encouraging the development of barriers against
Wallace was strongly attracted to unconventional ideas.
His advocacy of Spiritualism and his belief in a non-material origin for the higher mental faculties of
humans strained his relationship with the scientific establishment, especially with other early
proponents of evolution.
In addition to his scientific work, he was a social activist who was critical of what he considered to
be an unjust social and economic system in 19th
His interest in biogeography resulted in his being one of the first prominent scientists to raise
concerns over the environmental impact of human activity.
Wallace was a prolific author who wrote on both scientific and social issues; his account of his
adventures and observations during his explorations in Indonesia and Malaysia, The Malay Archipelago,
was one of the most popular and influential journals of scientific exploration published during the
Alfred Lothar Wegener
( 1880 -1930) was a German scientist, geophysicist, and meteorologist.
He is most notable for his theory of continental drift (Kontinentalverschiebung), proposed in 1912,
which hypothesized that the continents were slowly drifting around the Earth.
However, his hypothesis was not accepted until the 1950s, when numerous discoveries such as
palaeomagnetism confirmed his hypothesis of continental drift.
Alfred Wegener first thought of this idea by noticing that the different large landmasses of the Earth
almost fit together like a jigsaw.
The Continental shelf of the Americas fit closely to Africa and Europe, and Antarctica, Australia, India
and Madagascar fit next to the tip of Southern Africa. But Wegener only took action after reading a
paper in Autumn 1911 and seeing that a flooded land-bridge contradicts isostasy.
Wegener's main interest was meteorology, and he wanted to join the Denmark-Greenland expedition scheduled
for mid 1912.
So he hurried up to present his Continental Drift hypothesis on 6 January 1912.
He analyzed either side of the Atlantic Ocean for rock type, geological structures and fossils.
He noticed that there was a significant similarity between matching sides of the continents,
especially in fossil plants.
His hypothesis was thus strongly supported by the physical evidence, and was a pioneering attempt at
a rational explanation.
(1588-1654) was originally physician in Copenhagen, but it was as a naturalist
and founder of Denmark's very first museum that he inscribed his name in history.
The museum was named after himself, "Museum Wormianum", and was a true cornucopia of antiquities,
ethnographic items, and stuffed animals.
During the Renaissance such museums were established many places in Europe and called "Nature Cabinets"
and served as a kind of research libraries for anything not yet described in books.
The Danish museum no longer exists, but most of the items are now transferred to and on display in the
National Museum and Zoological Museum.
One stamp (the right one) of "Drawings of fossil animals from old books - Historiske Fossile" set
issued in Denmark on 1998 shows Ammonit parapuzosia
, a fossil discovered by Ole Worm.
The stamp is part of a souvenir sheet containing four different stamps on historic fossils.
