Cow shark tooth

[Rita__]

Hey everyone,

 

I found this cow shark tooth in a creek in Gainesville yesterday. Needless to say, I’m super stoked about it! Curious if anyone can tell me which type of cow shark? or any other input would be appreciated. Thanks!

I don't know the stratigraphy of Gainsville, but i'd say Notorynchus cepedianus lower tooth if Miocene..

From the book on Gainesville sharks teeth (Boyd, 2016), I would call it Notorynchus primigenius and according to the book, complete ones like this are pretty rare, so well done.  It is a beautiful tooth.

For the record, cepedianus and primigenius are the same species. Primigenius was the fossil name which has been discarded as the fossil shark is considered to be the same as the extant shark.

Thank you for the input everyone! And yes @jikohr I was completely floored when it showed up in my screen. A dream come true lol was not expecting it! And @ClearLake I’m looking everywhere to find that book you referenced so I can purchase a copy but I can’t seem to find it!

Thanks @shark57, I was not aware that the two had been combined. I’ll make a note of that. 
 

@Rita__ I think I got my copy from the U of Florida museum bookstore. Check their website if you don’t happen to live in the Gainesville area.
