Hello everyone. These two teeth were teeth I acquired from a fossil hunter in Russia. The first tooth is a double tipped Archaeolamna sp. The second tooth is a pathological Cretoxyrhina vraconensis (denticulata according to Russian literature). I've got a lot of non-pathological Cretoxyrhina, Squalicorax, Dwardius, etc. if you guys want to see those as well.

Where can I find information about the taphonomy of the Asery (Aseri) Level in the St.Petersburg region, Russia?
Oxytropidoceras posted a topic in Questions & Answers
Has a comprehensive study of the taphonomy of the trilobites found in the Asery Level, Simankovo Formation, been published in either English or Russian? If so, where has this research been published? I have found online a copy of: Ivantsov, A. Y. (2004) Ordovician Trilobites of the Subfamily Asaphinae of the Ladoga Glint. Paleontological Journal v. 37, supp. 3, pp. S229-S337. https://www.researchgate.net/publication/260191469_Ordovician_Trilobites_of_the_Subfamily_Asaphinae_of_the_Ladoga_Glint https://www.academia.edu/2353004/Ordovician_Trilobites_of_the_Subfamily_Asaphinae_of_the_Ladoga_Glint However, I would like to find a more detailed discussion of the taphonomy / sedimentology of the the Asery Level, Simankovo Formation if it exists in either English or Russian. More details are in "What's the age of Asery Level" at http://www.thefossilforum.com/index.php?/topic/83363-whats-the-age-of-asery-level/ Any citations that anyone can recommend would be appreciated. Yours, Paul H. -
I just saw this could it be a pliosaur tooth, measures 3cm long and found in Russia?

Teeth like this confuse me - i believe it is either a Plesiosaur or Pterosaur tooth (listed as Pterosaur from the seller) and it comes from the cretaceous sediments of Stariy Oskol, Belgorod region in Russia according to the description. It is 4cm in length. Any idea what this tooth most likely is? Thanks.
