Spitsbergen Expedition: Animals Big and Small

2011 Emerging Explorer Jørn Hurum is currently leading a fossil-finding expedition to Norway’s Svalbard archipelago, continuing the work that has yielded many spectacular fossils through the years (Giant “Sea Monster” Fossil Discovered). Follow the expedition here on Nat Geo NewsWatch.

Day 6

Just as the team was finishing breakfast  and getting ready to head out to the Konus valley dig sites this morning, a white dot moving on the shore down from camp caught our attention: a polar bear. The crew rushed up the hill with weapons, flares, binoculars, and cameras to follow the movements of the animal. The bear seemed curious and walked up and down the beach for a while, then finally retreated in the next valley. With this threat so close, the nightly bear watch has now been extented to daytime. If the wind turns, the bear could be in camp in a matter of minutes.

Most of the crew nevertheless walked out to the three new quarries in Konus valley. As more bones are revealed from the shales, the team excitement grows. Ancient animals, plesiosaurs and ichthyosaurs, are coming alive under our picks and brushes. Protective plaster jackets are made over the exposed skeletons. A couple more tons of rocks are dug out of each quarry. The excavation work is going on at full speed.

A smaller scale excavation also took place near camp, as Magne discovered a small concretion layer with 9 beautifully preserved sea urchin fossils. The rounded urchins may only be 15 cm in diameter, but their presence here is impressive as only a few echinoderm fossils are known from the Mesozoic arctic.

During the past two field seasons, multiple echinoderm fossils were collected by the team from Janus mountain. It now constitutes the best known collection of Mesozoic arctic echinoderm fossils in the world. The day was thus a general amazement of encounters with animals, extinct or alive, big or small.
