val horn Posted January 17, 2021 Share Posted January 17, 2021 My local fossil site is a late marine cretaceous site with abundant fossils with poor preservation. Over time I have collected several vertebral centrum that are concave on one surface and convex on the other. Is it possible to separate croc from mosasaur on these beat up pieces. What criteria can one use. Link to comment Share on other sites More sharing options...
The Jersey Devil Posted January 18, 2021 Share Posted January 18, 2021 Interesting. I heard the Maryland Cretaceous was mostly built over and inaccessible nowadays. Croc verts usually have more exaggerated faces. The small vert on the second row in the first picture looks like Croc, although I'd like to see better pics. The preservation on the rest isn't too great, but they're most likely mosasaur. Nice stuff! 1 “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...
caterpillar Posted January 18, 2021 Share Posted January 18, 2021 I think all is mosasaur. The small vert is just a mosasaur cervical vert 1 http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
