Spitsbergen Expedition: More Fossil Finds and a “How-To” Lesson

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 7

A busy day today, full of plaster and new discoveries.

We opened up one of the Konus Valley ichthyosaur fossils nicknamed “Virgin”. This fossil includes the front half of an ichthyosaur and it is in good shape. Julie, Aubrey and Lene uncovered its skull and the second front limb. The jaw bones in particular are in very good condition.

Long converging ridges in the rock clearly mark out the shape of an ichthyosaur skull, to those with a trained eye. Photo courtesy Jørn Hurum.

 

Over at the Konus valley we finished plastering and flipping the plesiosaur. The plaster is put on the fossils for protection and transport. The method we use is as following:

1. We apply 4 to 5 layers of wet toilet paper, to prevent the bones sticking to the plaster’

2. We cover the toilet paper with a thin layer of runny plaster to make sure that the plaster gets into every nook and cranny.’

3. We then soak wet burlap in the plaster mix and wrap around the fossil. We add several layers of burlap and sometimes steel bars to stabilize it.

4. After the plaster has set, we undercut the jacket and hammer in meter long chisels.

5. To flip the plaster jacket we attach ropes to the chisels, and pull.

Back near the camp, Nille found a new ichthyosaur. This fossil looks very promising and we will start uncovering it to tomorrow. So stay tuned!
