On commemoration of Indian
Geological Survey centenary on 13th January 1951 Indian
Postage released The stamp shows two individuals of Stegodon
ganesa,
the first ever reconstruction of a prehistoric animal on a stamp.It was
valued 2 Anas.Ana the olden Indian coin was in use before 1956. In 1956
Indian Government introduced Paise the hundredth fraction of Rupee the
currency.16 Anas are equal to One Rupee.
The stamp is based on picture published by Henry
Fairfield OSBORN in "Proboscidea.
A monograph of the discovery, evolution, migration and extinction of
the mastodonts and elephants of the world. Vol . 2, Stegodontoidea,
Elephantoidea." , issued in New-York, USA in 1942. (1st
edition of the book from 1936, 878
pages, can be downloaded from Open
Library web siite)
Note:
On March 4, 2001 a
another stamp was issued by the Department
of Post, Government of India, to commemorate 150 anniversary
of
Indian
Geological Survey
This
time geological motive has been choosed. The four colour
stamp shows bauxite (aluminium ore), chalcopyrite (copper ore) and
psilomelane (manganese ore). The denomination of the stamp is 300 paise

Stegodon
ganesa
In 1928 century 3 metre long fossil tusk of an elephantine
mammal Stegedon ganes
a found in India by Dr.
Darashaw Nosherwan Wadia (October 25, 1883 - June
15, 1969) who pursued his personal research on stratigraphy, structure
and palaeontology of the Kashmir Himalaya with single-minded devotion.
Having a very keen eye for observation, he worked towards
identification of broad structural elements of the NW
Himalaya. The fossil tusk is now kept at the Museum of the Geology
Department of the Jammu University. The discovery of this skull, which
was found in association with fossil ganoid fish and pteridospermous
plants, led to the fixing of the age of an important geological rock
formation in the Kashmir Himalaya to the Permo-Carboniferous time (355
- 250 million years).

Stegodons are primarily an Asiatic group
of mammutid origin, this family is believed to have evolved sometime by
the middle Miocene, nearly 15 MY ago and became extinct by the late
Pleistocene about 30,000 - 40,000 years ago. Stegodons appear to be
transitional between true mastodons on the one hand and true elephants
on the other.
Like elephants, stegodonts must have been
good swimmers. Their fossils are frequently encountered on Asian
islands, which even during periods of low sea-level (during the cold
phases of the Pleistocene) were not connected by land bridges with the
Asian continent . A general evolutionary trend in large mammals on
islands is island dwarfing. The smallest dwarf species, Stegodon
sondaari, known from 900,000 year old layers on the Indonesian island
of Flores, had an estimated body weight of 300 kg (661 lb), smaller
than a water buffalo. A medium to large sized stegodont, Stegodon
florensis, with a body weight of about 850 kg (1,874 lb), appeared
about 850,000 years ago, and then also evolved into a dwarf form,
Stegodon florensis insularis. The latter was contemporaneous with the
hominin discovered in 2003, Homo floresiensis, and disappeared about
12,000 years ago.Stegodon tetrabelodon syrticus was a spectacular late
Miocene species with four tusks described from a partial cranium and
jaws found in North Africa
