The hunt for fossils in the far-flung reaches of Svalbard is on! Jørn Hurum and his associates ply the arctic waters and snows of Svalbard to dig up some of the northernmost dinosaur fossils in the world. Their findings, particularly of ichthyosaurs, are some of the most unique on record.

It’s day three of our expedition, and we had our first visit from tourists. Doing outreach here in the field is a great way to show people our work. Although we mostly had fish fossils at that time, they illustrate the processes of fossil formation and excavation.
Among the group were Aubrey’s parents, celebrating her father’s birthday. They also brought us a fancy English fruit cake. It was devoured quickly by already-missing-normal-food campers.
On our way up the hillside, Stig made the first significant discovery of the Spitsbergen Mesozoic Research Group; a fantastic ichthyosaur tail, perfectly illustrating the tail of primitive Triassic ichthyosaurs. In later ichthyosaurs, the tail vertebrae bends steeply downwards and cartilage forms a lunate, fish-like tail. In their more primitive ancestors, the tail bend is not as strong and the spines on the vertebrae form more of the tail, giving the ichthyosaur a more eel-like look.
After lunch (at 7 p.m.), we went for a walk further up the valley, towards the glacier. Here, we discovered bright-blue bones on the surface of an otherwise black slope.
After just a couple of enthusiastic hours, we found loads of bits and pieces of several ichthyosaurs. Some bones must have belonged to typical, small-size ichthyosaur. But one of them, was a Triassic mega-ichthyosaur! As usual, we only found bits of its tail.
We had to go back for dinner around 11 p.m., to continue looking tomorrow. Although some of us might have wanted to stay a while longer, we move in groups as we always have to carry firearms in case of polar bears. And according to some of the tourists who visited us, they spotted one just across the fjord a couple of days ago.
Not all of us were out crawling slopes for bits of ribs. Hans Arne and Oyvind Hammer walked over the mountains and far away, to explore new areas and learn more about the area’s geology. According to Hans Arne’s GPS, they were out for a total of 3 hours and 19 minutes, while they were standing still for 3 hours and 15 minutes—typical geologists. So many pretty rocks!
