Hello everyone ! I bought this Tyrannosaur tooth and the seller told me it was either a Tyrannosaurus rex or a Nanotyrannus. Can you tell me if it's a T-rex or a Nanotyrannus ? It's a premaxillary tooth. It comes from Hell Creek formation in South Dakota.

Would any metal fossils remain after 65 million years?
chrismackey posted a topic in General Fossil Discussion
Would any metal, specifically colbalt chrome fossilize? I'm asking because I have a book where a time portal opens to 65 million years ago, a character stabs another and the blade breaks off in the dead man's chest, and he gets buried under a mudflow. They find his fossilized remains in the present day, but would the broken blade still be stuck in his bones? Any help would be appreciated. Thanks! :)- 17 replies

Hey, a question I have always wanted to ask is about dinosaur relatives, more specifically what do we mean when we refer to two dinosaurs as cousins ? Do we mean that a kind of dinosaur(for example baryonyx ) lived in an environment but at one point a group got separated by land and this group got to live in another part of the world so that group resulted in adapting to another environment and becoming a different dinosaur (for example spinosaurus ) or do we mean that a dinosaur is an ancestor of another dinosaur (again for example baryonyx evolved into spinosaurus)? This may seem like a really basic question to ask but I haven't really been able to find an answer so if someone answered it would be great.
