Questions about any large and currently unnamed Ctenacanthiformes sharks known
Joseph Fossil posted a topic in Questions & Answers
As I have been researching large ctenacanthiform sharks from North America, I've been wondering if there are any known globally that are currently unnamed. I definitely know of the large Ctenacanthiformes Saivodus stratus (found in both what is now North America and Great Britain), the large Ctenacanthiform from the Permian Kaibab formation in Arizona, and the 'Texas supershark' (a likely large species of Gilkmanius) from the Pennsylvanian Texas Graham formation (all three as larger or larger than an adult Great White Shark (Carcharodon carcharias)). But are there any large ctenac- 2 replies

Came across this tooth, the location is: Severst Sandstone Formation Volga River Region, Russia Late Jurassic 145 Mya. The striations tells me it's ichthyosaur, but the root looks pliosaur to me, do I'm curious. What do people here think? It's 34 mm long @pachy-pleuro-whatnot-odon

First of all - sorry for bad and rude language)) So, I need some help with identification of this teeth. All was found in Russia, Trans-Urals region, in a few different rivers: Belyakova, Sugatka and Derney. There must be Eocene period, probably lutet or barton layer, but I can't be sure, because there is no bedrock, only fossils that river stream brings. Sometimes me and other people found there more old fossils, back to cretaceous even. I showed this photo to few reptile specialists from Saint Petersburg, but they sure that is no crocodile teeth, and insist that is a fish teeth. But i have f

Australiceras/Proaustraliceras Ammonite?
Mochaccino posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, I came across this listing for a Australiceras/Proaustraliceras ammonite from the Cretaceous Volga River of Russia, about 12 inches long. In terms of restoration, it is just said to be "cleaned, prepped and stabilized". To my amateur eye, there are no suspicious spots or abrupt changes in texture that would indicate reconstruction/restoration or compositing, and I think the matrix also looks typical of the region. What do you think? Any tampering going on or is it all-natural? Thanks. EDIT: I actually noticed- 2 replies

I picked up the shark tooth below a while back, labeled as Cretalamna borealis. I'm not very familiar with the species--does this ID appear to be correct? The label that came with the tooth says it was found near Stary Oskol, Belgograd Oblast, Russia, and that it's Upper Albian in age from the Kursk Osteolite member of the Seversk Sandstone formation. The tooth measures 38.6 mm along the slant. One of the root corners is missing and there's some hard matrix still cemented to the tooth near the root margin of the lingual side. @ThePhysicist, I think this one might be a D

Hello, I'd love some identification help on this lil ammonite fossil I purchased at the Tucson Gem Show. The dealers were Russian and all the info I could get was that the ammonites were Russian as well It is a bit pyritized. I bought 2, I used the larger one to make a mold and cast. The original did not survive the process so I have included pics of the cast (the one with the loop added, lol), I think it's easier to see details on that as well. Additionally, if you have any rec's for online or in print resources for ammonite ID they would be much appreciated. I found myself googl

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.

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).

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
