True North: Hunting Fossils Under the Midnight Sun by Lou Marincovich, PhD
Lou M posted a topic in Fossil Literature
Greetings! I spent my career as a research paleontologist with the U.S. Geological Survey (Menlo Park, California) and the California Academy of Sciences (San Francisco), specializing in Cenozoic marine mollusks of the North Pacific and Arctic oceans. My summer fieldwork for 34 years was in Alaska, Siberia and northern Canada up toward the North Pole. Several times I had the indescribable thrill of being the first collector, perhaps the first human being, to visit a remote fossil site, reached by bush plane or helicopter. I was often dropped off to spend the day alone at remote sit- 4 replies

Interesting article on a fossil tooth that his been "buried" in a museum vault for years. It was recently identified as a type of hyena that may have roamed the Arctic Circle. NYT subscribers, or those who haven't gone over a free limit, should be able to read. Cheers. Arctic hyena tooth fossil

Hallo, Does anyone know what this might be? I am hoping for a dinosaur skin inprint. :-) This was found on Svalbard on a spot where I also found bones from Plesiosaurs and Ichthyosaur. I am grateful for any help. Thanks! /Malin

Hi everyone ! Just discovered this forum and thought I should give it a go regarding identifying some trace fossils. I am currently working with the sedimentology of the Upper Triassic on Svalbard and in the Norwegian Barents Sea. Several trace fossils has been observed in the field and it would of course help a lot to identify them when it comes to the sedimentological interpretation. So, feel free to comment. - Picture 1 shows a vertical 'tube' burrow in a heterolithic setting (mud + sand). The preliminary interpretation is that it was deposited in the offshore-transition zone.
