Cretalamna Shark Teeth
UPDATE: Thanks to Lance Hall for a new identification of this fossil shark tooth. It appears to be a Cretalamna instead of a Scapanorhynchus that I originally reported. Go to Lance's great fossil site: http://northtexasfossils.com/

Those look more like Cretalamna to me. Scapanorhynchus is a long bladed tooth. If you can get a copy of "The Collector's Guide to Fossil Shark and Rays of Texas" it's worth every penny!

Thank you for the correction. I have updated this post.
ReplyDeleteThe area I live in has few shark remains but when we find them they are quite old (Devonian and Mississippian Periods).

The tooth on the top is a lower Cretoxyrhina mantelli, a very nice find.
