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.

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
