  1. 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 sites up to 60 miles (100 kms) away. I had a number of extreme adventures, including killing an attacking grizzly with my only bullet, fending off a pack of wolves circling me, crashing in a helicopter, escaping a landslide by jumping into a passing river raft, and near-drownings in icy rivers. Of course, it was all worth it because of the fossils! My main work was documenting Cenozoic faunal and climate changes in the Arctic. However, my most notable accomplishment was solving the age-old mystery of Bering Strait’s age, which was featured on the cover of Nature. Most satisfying was discovering an unnamed river in remotest Alaska and naming it the Spirit River. I’m happy to say that my friend Warren Allmon, Director of the Paleontological Research Institution, wrote, “This memoir is a can’t-put-down page-turner, equal parts Jack London and Marincovich’s idol Roy Chapman Andrews. It is not just a rip-roaring adventure story; it also eloquently communicates both the intellectual thrill of scientific discovery and the emotional (and spiritual) energy derived from genuine exploration in some of the most challenging — and beautiful — environments on Earth.” He and other reviewers commented on the laugh-out-loud humor in my book. My book won a Bronze Medal in the Adventure category of a national book contest, and it has become an Amazon #1 Best Seller in its category. Reviews of my memoir are on Amazon.com and Goodreads.com I hope that fossil enthusiasts here enjoy reading about my adventures and research. My web site at www.loumarincovich.com has an array of photos from my fieldwork days and a list of my larger publications. Lou
  2. Artic hyenas?

    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

  6. Trilobite

    This looks an awful lot like a Trilobite to me...found it by a brackish lake while trekking through the Arctic! If it is they're still living up here!
  7. Dinosaur Skin Inprint?

    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
  8. 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. Could also have been in a shallower pro-delta environment. Could it be Skolithos, or is it to 'wiggly' and thick? - Picture 2 shows a similar trace fossil (same facies as described above). - Picture 3 also shows one or two vertical burrows (same facies as described above). - Picture 4 shows some apparently vertical traces (same facies as described above). - Picture 5 shows a vertical trace found in a flaser heterolithic setting (90% sand + 10% mud). As you can see, it cuts through the layers and bends them a bit downwards. Preliminary interpretation is a tidal sand flat. - Picture 6 and 7 shows some thick horizontal burrows. Found in a 1 m thick sandstone with hummocky cross stratification and wave ripple cross lamination. Preliminary interpretation is a lower shoreface setting. Could it be Rhizocorallium? Cheers!
