There are Eurasians, East Asians, North Americans, paleo Siberians, neosiberians and Ancient North Siberians. I'm probably confused. Read the article. https://news.google.com/articles/CAIiEObRZyc-f3YxuaCQaLR-phsqFggEKg4IACoGCAowl6p7MN-zCTDlkko?hl=en-US&gl=US&ceid=US%3Aen

Araucaria Leaves from Russia?
Zapsalis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello Fossil Forum, I found a supposed Araucaria fossil leaf from the Russian Federation for a very low price on our favorite site, eBay. The dealer claims that the fossil is an unknown Araucaria species from the Upper Jurassic of Lena River Basin, Markha River, Siberia, Russia. Is this fossil legit and should I buy it?- 1 reply

Hi, I'm sorry the first photos didn't come out but I needed the youth to help me out As i said, I was in contact with someone from Russia who has said he dug fossils of mammoths and he had some mammoth teeth for sale. He sent me photos of which I enclosed one . I was just curious as the quality of these fossils were amazing. I just question if these are truly 10000 year old fossils dug from the permafrost. Can you just advise if you feel this is a true mammoth fossil.

HI, I am new to fossil collecting and I wanted a mammoth tooth for my office. Through the internet , I contacted a fellow in Russia who claimed to have dug mammoth fossils . He sent me some photos. I'm no expert , but this looks fresh to me . I asked are you sure this is a 10,000 year old fossil and not from a modern day elephant and possibly from poaching . His reply was that the permafrost is an excellent preservative and they had found animals with skin and hair . What is your opinion.

Prelude to the extinction: Achchagyi-Allaikha and Berelyokh Mammoth Bone Beds
Oxytropidoceras posted a topic in Fossil News
A great paper about classic Siberian mammoth bone beds. Nikolskiy, P.A., Basilyan, A.E., Sulerzhitsky, L.D. and Pitulko, V.V., 2010. Prelude to the extinction: revision of the Achchagyi–Allaikha and Berelyokh mass accumulations of mammoth. Quaternary International, 219(1), pp.16-25. https://www.researchgate.net/publication/248478864_Prelude_to_the_extinction_Revision_of_the_Achchagyi-Allaikha_and_Berelyokh_mass_accumulations_of_mammoth https://www.researchgate.net/profile/Pavel_Nikolskiy/publications In part, the abstract reads: "The formation of the burials is a direct consequence of short but strong climatic warming (Bølling Oscillation) that resulted in many unfavorable environmental conditions. Among these, the increase of snow cover and stronger spring floods were very notable. Bølling warming is a model of the large-scale Holocene event. Mass death of mammoths during the Bølling phase was a prelude to their final extinction." Also, there is: Nikolskiy, P.A., Sulerzhitsky, L.D. and Pitulko, V.V., 2011.

Woolly Mammoth Tusk - Real?
DinoNewbie posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, this is my first time posting as I am new to the forum. I am considering buying a Woolly Mammoth Tusk for Christmas, but I do not know how to know if it is a real or a good quality item. Would you all be able to provide your guidance? It says cracks near the base have been filled with glue. It says it is the tip of a larger tusk. It says it is 23" long, circumference is 8" and weighs 4 pounds. It says the species is Mammuthus Primigenius (woolly mammoth), location Belovo, Kemerovo oblast, southwestern Siberia in Russia, Age 22,000 years old. Also, if you could provide names of good quality honest vendors that sell in the US that would be great. -
Dear members of The Fossil Forum, I am busy on the identification of all the fossils in my collection, but some fossils are causing trouble, one of which I will show here. It is 23mm. The name tag says it is an Arctohungarites sp. but in my opinion the umbilicus is too big for Arctohungarites. It looks more like Nordophiceras but I do not know if the fastigate venter is common for that genus. It might very well be neither of these genuses, my knowledge on Siberian ceratites is very limited. The findspot is Northern Siberia, but where exactly is not stated. I know of two sites, Cape Tsvetsov and the Olenek river, does the preservation of this ammonite point at one of these two? The age of the ceratite is said to be Middle Triassic, which means Anisian-Ladinian, although most of the siberian triassic ammonites are Olenekian in age. Apparently Arctohungarites is an Anisian genus, but I am not sure that this ammonite is an Arctohungarites. So my questions are: What Genus and species is this ceratite? Where does it come from? What age is it? Is there anyone who can shed light onto this ceratite and help me? Thanks in advance, Sander
