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.

Spino tooth wear and tear
Mahnmut posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello together, some time ago I bought a nice big Spinosaurus tooth I am quite happy with. I only wonder when its tip got its shape: when the animal was still alive and chewing fish , when the fossil was (partially) in the ground or when it was in the preppers workshop. Any opinions on that one? thanks in advance, J -
Nevermind that the authors got the age wrong by a factor of 1000! They thought it was 500,000 years old but they say Cambrian so I guess it is 500 million years old. https://news.google.com/articles/CAIiEGCPp7KKbJYVK8AnXN7shMsqGQgEKhAIACoHCAowrq6BCzCw9PwCMMjF7gU?hl=en-US&gl=US&ceid=US%3Aen

Does anyone know of deposits other than the LeGrand crinoids where each species is preserved in a different characteristic color, all on the same slab? We have this kind of thing in the brachiopods and trilobites of the Decorah Formation (Late Ordovician) here in Missouri, which is what got me thinking about it. But I've never seen a report summarizing other cases of this phenomenon, and as I think about it I'm not sure I can name any others. Can you?
