Mammoths and other large animals survived in the north much longer than previously believed. New DNA research indicates that the climate, not humans, led to the demise of these large creatures, Norway Science, January, 2022 The open access paper is: Wang, Y., Pedersen, M.W., Alsos, I.G., De Sanctis, B., Racimo, F., Prohaska, A., Coissac, E., Owens, H.L., Merkel, M.K.F., Fernandez-Guerra, A. and Rouillard, A.,2021. Late Quaternary dynamics of Arctic biota from ancient environmental genomics. Nature, 600(7887), pp.86-92. It concludes that mammoths survived in continental northeast Siberia until 7,300 BP; North America until 8,600 BP; and the Taimyr Peninsula as late as 3,900 BP. Yours, Paul H.

I just had the opportunity to purchase a kimberella fossil for a good price but backed out at the last second because the seller was based in Russia and I wasn't sure about the legality surrounding White Sea specimens being imported to Canada where I live. I'm always wary of fossils being sold out of China and Russia. Has anyone purchased White Sea specimens directly from Russia? And what is the legality of them? It's hard to find a direct answer online.

***Need professional help with Paleogene/Eocene shark teeth identification***
Morte posted a topic in Fossil ID
Hello everyone!)) Need help of paleontologists and paleoichthyologists with identification of eocene shark teeth from Russia. I'm not professional, just a fan and rooky, so I choose possible species options for every tooth, according to books and scientific publications which I have. Hope I make right something at least. Be glad and thankful if somebody will help me figure it out)).

Greetings from a novice amateur of paleontology from Moscow
Pauli W. posted a topic in Member Introductions
Greetings to the forum participants! My name is Pauli or Pavel. I am from Moscow (Russia). Newcomer to paleontology since 2021. I adored dinosaurs as a child! Now I have two small children and they also adore dinosaurs and help me look for fossils! In our region there are deposits of Carboniferous, Jurassic and Cretaceous, as well as Quaternary moraine deposits. Among the fossils, the inhabitants of the seas predominate (brachiopods, gastropods, belemnites, ammonites, sea urchins, sea lilies, etc.). I will be glad to share some of my modest finds. Below in the photo are some of the places of my finds (forest streams).

My Jurassic Park now heads across the pond to England and Germany. Dinosaur material from these countries is not common like North America and in fact very difficult to obtain. Theropod material is extremely rare and most remains are fragments. Most of my material from England comes from the coast of two areas The Isle of Wight and East Sussex. Material from these area comprises the Wealden Super Group (Hasting+Wealden+Weld Clay) and is early Cretaceous from the Valanginian to Barremian Stage (140-125mya). Yellow - Hasting Group , Green - Weald Clay Red - Wealden Grouip Theropods Baryonyx walkeri My collection includes two examples of this Spinosaurid from England. One tooth is partially rooted. Megalosaurus bucklandii One of the large theropods of region. This tooth was found encased in a block and the tip was restored based on the matching blocking Dromaeosaurid indet A very cool small theropod tooth. May not have yet been described.

I recently acquired two Cretaceous lamniform shark teeth that I'm trying to identify. The first one, from Russia, was sold as Cardabiodon sp., but I'm curious if that's correct or if it's something else. The second tooth, from Texas, didn't come with an ID. Thanks in advance for any help you can provide! #1 - Cardabiodon? sp. This tooth is from the Cenomanian of Russia and was found near Fedorovka Village, Tambov Region. The tooth measures 28.51 mm on the slant and 14.91 mm at its widest across the root. #2 - Unidentified This tooth is from the Lake Waco Spillway in Texas, from the Del Rio Formation, which I believe is Albian in age. The tooth measures 15.93 mm on the slant and 11.15 mm at its widest across the root.

I found this fossil gastropod on an auction site and I really liked it. But the information is a bit confusing. On the title it states that it is Cretaceous but in the description of the seller it says "Cretaceous-Oxfordian-160 MYA". Oxfordian is a period from the Jurassic, not the Cretaceous. The locality & species (theres 2 species) Location: Kostroma Region Russia Species: Pictavia laevigata & Exelissa quinariia .

Rovno Amber (Mezhigorje Fm., 33.9-28.1 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Two pieces, roughly weighing 7 and 4 grams respectively. Both are mined from the Rivne region of Ukraine's Rivne Oblast, and had a little to no oxidized layer, in comparison to amber mined from the nearby (roughly 50 km) Klesiv Deposit.© Kaegen Lau

Rovno Amber (Mezhigorje Fm., 33.9-28.1 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Roughly 12g specimen of amber mined from the Klesiv Deposit of the Rivne region in the Rivne Oblast of Ukraine. It was originally coated in a 2mm red oxidized crust, typical of this locality. It is believed that the presence of this crust is an indicator that amber from this particular locality underwent little to no re-deposition throughout its diagenesis, and oddly contains the majority of described insect-included Rovno material.© Kaegen Lau

Rovno Amber (Mezhigorje Fm., 33.9-28.1 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
19.0g specimen of hand-polished amber from the Rivne region of Ukraine. It contains numerous botanical debris, although I have not observed any definitive insect inclusions. It is what would be termed a "run"; this specimen has over 12 successive layers that would have run down the side of the tree (the depicted piece would be properly-oriented if rotated 90˚).© Kaegen Lau

Rovno Amber (Mezhigorje Fm., 33.9-28.1 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
83.8g raw amber mined from the Rivne region in Ukraine. The "eye hole" was likely formed when the organic matter (i.e., tree branch) the resin encased, was likely dissolved/washed away during the resin's diagenesis and redeposition (Baltic and most Rovno material is generally believed to have been redeposited).© Kaegen Lau
