Sea Monsters of the North: Day 1

NG Emerging Explorer Jørn Hurum is currently on Spitsbergen Island in the Arctic Circle excavating the remains of ancient marine reptiles worthy of the most fantastic Norse legends. Follow the expedition here on Explorers Journal through updates from him and his team, and catch up on his previous expedition for more.

It’s a good start, a skull after four hours. Possibly one of the largest too.

We knew there were several plesiosaurs and ichthyosaurs in the mountain slope behind the camp. They were registered at the end of last year’s field season. The plan for this year’s first day was to examine which fossils were the best candidates for opening a quarry. This could be the last season for the Spitsbergen Jurassic Group, and therefore we should make sure that we bring home the best specimens.

And it’s looking good. Tommy started working right after breakfast. The only thing visible was some rib ends. Nothing spectacular, just a pile of rocks.

“A couple of hours passed before I realized this wasn’t ribs,” says Tommy. Direction and shape rather suggested that he was working on the underside of a skull.

“My only thought was, this is too good to be true!”

And so the Spitsbergen Jurassic Research Group 2012 got a flying start, the skull of a fair sized ichthyosaur.

One hundred meters and 20 million years further down the hill, expectations are through the roof. Here Pat and Jørn are working on the ichthyosaur the stumbled upon on last year’s final day. This animal lived earlier in the Jurassic, which makes it interesting to Pat, one of the world’s leading experts on these marine reptiles.

“Knowledge is always interesting,” he says. “We know a series of specimens from Tommy’s layers, much less from down here.”

Jørn marks a perimeter around the central finding, Pat defines sections within the circle and Stig, Bjorn and myself help pick away loose rocks from the surface. Those containing bone fragments are put in plastic bags, the rest is laid aside. Soon we see a dark, earth-colored circle growing from the center.

After a couple of hours we are left with the treasure itself, but sadly Pat and Jørn are let down. The skeleton, encased in solid rock, has almost become powder, and seeps out when we try to remove the rocks.

“We hope the inner parts are more intact. What we are looking for are parts we can use. We think we have got a shoulder we can use, and one half of the lower jaw was of good quality,” says Jørn.

Pat on the other hand claims to have seen worse specimens prepared and described before, so the paleontologists agree on packing the animal in boxes and bringing it home.

“But I guess I am a bit disappointed. I had great expectations for this one,” says Jørn.

The first day of digging on the expedition has its ups and downs. The entire day before was spent making camp, a challenge in its own right, 400 meters up the mountain side. The substrate had to be evened out, and a thousand details (fireplace, storage for food, trip wires for polar bears, gun rack, sleeping tents) had to be fixed before we could go to bed.

And last but not least, we of course needed to set up a latrine with a scenic view over at least five glaciers. No wonder Stig was grinning.

    Eager to read your upcoming blog Jørn – first scientific blog to seriously interest me! All the best from a sunny Skedsmo.

    If only you invented scientific separating tool for the rocks and so called fossils.
    Just have a think about it, ;)

    We found the first skeletons in 2004 by searching near the end of the rainbow! Jørn’s crew is just fantastic, a bone beneath every pile of shale. Best of luck to you all!
