I have a few unknowns from the Cenomanian of Russia that I am starting to get around to photographing and identifying. I am practicing with my actual camera instead of my phone so the pics are just ok but will get better lol
The first one is from near Fedoravka Tambov Region of Russia.
This one is about 13 mm or so. I think the ID when purchased was Cretoxyrhina but I do not know how accurate that is. I thought perhaps Cretalamna or maybe Dwardius or something completely different. I just do not know. It is a really striking tooth though and I would like to get some idea of what it is.
