  1. This nice Permian Brachiopod has a very large apsacline ventral interarea and is called Arctitreta triangularis. It is from the Assistance Formation in the Artinskian of Devon Island in Canada. It is related to Schuchertella and the more common Streptorhynchus. Does anyone else have any interesting Brachiopods from the Permian?
  2. Can anyone identify these trilobutts for me @piranha and possibly the nautiloid too, from Ellesmere Island, in the high Arctic of Nunavut? I acquired them from a local dealer because they were cheap but of course the information is not as extensive as one would like.... He had a few more things from Ellesmere also including a Maclurites-type gastropod and a segment of a larger nautiloid, kind of grotty but perhaps I should have bought them too to keep the collection together. (I could still do that) I can't find much in the way of papers online about this stuff from the little info I have except that there is Lower Ordovician rock containing Maclurites from the Bache Pen. on the E side of the island, but I can't find any Ordovician St. George Group except in Newfoundland.
  3. A worm that survived 46,000 years in permafrost wows scientists Emma Bowman, NPR radio, July 30, 2023 Nematode resurrected from Siberian permafrost lay dormant for 46,000 years By Sascha Pare, LiveScience, July 27, 2023 Worms Revived After 46,000 Years Frozen in Siberian Permafrost Scientists want to understand how the worms survived in extreme conditions for extraordinarily long periods of time. By Orlando Mayorquin, New York Times, July 29, 2023 The open access paper is: Shatilovich, A., Gade, V.R., Pippel, M., Hoffmeyer, T.T., Tchesunov, A.V., Stevens, L., Winkler, S., Hughes, G.M., Traikov, S., Hiller, M. and Rivkina, E., 2022.

  4. Found on an island in the Canadian Arctic. I think it's a Mosasaur tooth, but I'm really a newbie at this. The whole piece is about 3 inches in length. Thanks for any help!
  5. Scientists have revived a ‘zombie’ virus that spent 48,500 years frozen in permafrost By Katie Hunt, CNN, March 8, 2023 The open access paper is: Alempic, J.M., Lartigue, A., Goncharov, A.E., Grosse, G., Strauss, J., Tikhonov, A.N., Fedorov, A.N., Poirot, O., Legendre, M., Santini, S. and Abergel, C., 2023. An update on eukaryotic viruses revived from ancient permafrost. Viruses, 15(2), p.564-570. Another paper is: Miner, K.R., D’Andrilli, J., Mackelprang, R., Edwards, A., Malaska, M.J., Waldrop, M.P. and Miller, C.E., 2021. Emergent biogeochemical risks from Arctic permafrost degradation. Nature Climate Change, 11(10), pp.809-819. Yours, Paul H.
  6. Hi, I was wondering if anyone could suggest an interesting fossil I could add to my collection that is from the Arctic Ocean. Fossil Walrus tusk is not allowed in my state and I'd like to add something from this locality. I was thinking the Greenland sleeper shark fossil teeth as it is the oldest vertebrate but I'm not sure how to identify one that would have traveled to the Arctic Ocean as I'm not aware of any collections in the arctic as opposed to closer. Is there any other interesting fossils that would be known to be from the Arctic Ocean? It is the last region not already in my collection. I'm new to fossil collecting but I have already obtained land collections from all the continents and oceans other than the arctic and southern. Does anyone know of coral from the Arctic Ocean/coastline or anything else that might be interesting. Not sure if this is really fossil related but Deep Sea vents might be interesting if anyone knows where to trade/buy specimen samples from either in the Southern or Arctic Oceans?

    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
