Fossils From Nansen’s Fram Expedition

Most people don’t know this, but Nansen also mapped geological features and collected fossils on his polar expedition with Fram. While on Franz Josef Land, he took samples of fossils that have subsequently been important in understanding the geology of the archipelago and the formation of the Barents Shelf.

Nansen spent a few days at Cape Flora on Franz Josef Land, where he met Frederick Jackson’s expedition group. Together with the group’s geologist, Nansen mapped the area and collected a number of fossils and rock samples. These fossils were sent to the German geologist Josef F. Pompeckj, who published the findings in 1900.  

The collections at the Natural History Museum contain a number of objects that were collected on Nansen’s expedition across the Arctic Ocean in 1893–96. The paleontological collection contains a number of fossils, including ammonites, which are an extinct group of octopuses with an outer shell. These types of fossils are very important for dating and correlating sedimentary rocks.

Franz Josef Land’s geology was only partially investigated before Nansen arrived in the archipelago, and the results of the expedition have been frequently cited. The German geologist Josef F. Pompeckj described new species from Nansen’s collection, including the species Cadoceras nanseni and Pseudomonotis jacksoni – names that clearly emphasise Nansen’s and Jackson’s importance in Arctic exploration.

New objectives and methods in paleontological research have cast new light on the material in recent years. There is great interest in the geology of the High North, on both the Norwegian and Russian continental shelves. Nansen’s samples have been used in micropaleontological investigations as microalgae, spores and pollen are used to date the sedimentary layers.
