David Harper is Professor in Palaeontology at Copenhagen University. That makes him Curator for the Palaeontological collection, including the Type Collection at the Geodetical Museum in Copenhagen, part of the State Natural History Museum. His investigation fields are aimed at fossils and ecological systems in the lower Palaeozoic in Greenland, Great Britain and China. David Harper is also Chairman of a number of commissions and union.
The geology of Greenland has a remarkable large number of rock structures that stretches over almost four billion years of history of the Earth. In fact, sedimentary deposits from Isua in West Greenland reveal the earliest proof of known life, in the shape of micro-organisms, existing 3,8 billion years ago. Life developed later in species and numbers and left its marks on geological history. Rocks and fossils in Greenland have given us an insight into the development of animals and plants throughout the history of the Earth. The first series of stamps on this subject illustrates important events in life on Earth by showing unique fossils from Greenland. In the geological Age, Cambrian, a riot of different species arose, which later lead to the inhabitation of the earth and the sky by toads and pterodactyls respectively.
Halkrieria evangelista is an astonishing animal. It looks like a worm with two shells, one at each end of its body. It was first found in Cambric rocks on Bornholm; only a few shells were found which, for the most part made it look like a sea shell. The fossil from the Pass of Sirius in North Greenland was collected by The Geological Institute of Greenland in 1980. The find was complete with two shells and it showed that it belonged to the mollusca but it did not look at all like something we know of today. The fauna of Sirius contains many strange and undiscovered animals and that testifies to a world-wide development of new kinds of life, e.g. during the Cambrian Explosion 250 billion years ago, when a high amount of new complex organisms developed very fast.
Ichthyostega stensioei is one of the first amphibians. In the geological age, Devonian, the land was already green and contained different species of spiders, insects and molluscs. At the end of Devonian about 360 million ago, the vertebrates followed. The first specimen of Ichthyostega was collected by Swedish expeditions in East Greenland in the 1920s and 1930s. At first it was taken for a terrestrial toad, but later it came to show that it lived in water; however, sometimes it would pull itself ashore, where it most likely fed on insects.
Eudimorphodon cromptonellus is a small pterodactyl that was one of the first vertebrates to develop the ability of flying.
The specimen was found by the Carlsberg Fjord in East Greenland in the 1990s by an expedition from Harvard University. Eudimorphodon existed in Greenland at the same time as the first dinosaurs (such as Plateosaurus), toads, fish and mammals. The sky was crowded with flying insects and hovering lizards but proper pterodactyls were the first to develop flying at own force in Sen Trias, 220 billion years ago. The mentioned fossils can be found at the Geological Museum in Copenhagen.
