Shark teeth from UVALDE county

[Tynator]

These teeth were collected on a private ranch in Uvalde county. I have tried finding resources about shark teeth in Uvalde county but have turned up blank. What formation have these come from? What species are they?

They may have come from the San Angelo formation,  clearer pictures with scale will be helpful for ID. Someone knowledgeable with that area and teeth will hopefully help out.

It’s always a good idea to include a rule for scale in your photos to help with IDs.

 

Having said that, the largest tooth at the top looks like an Enchodus sp. fang. The tooth second from the bottom on the left (the one with serrations) is Squalicorax — S. kaupi I believe. The one just above that (with the cusplet) is likely Scapanorynchus sp. Some of the other partials may be Scapanorynchus sp. as well.

Whatever formation they will be late Cretaceous in age based on the identifiable species present.

My first guesses would be Escondido or Anacacho fm, in that order.  What associated fossils were found in the same exposure?  Do you have any photos of the exposure?  Was the lithology more of a broken down gray to orange clay, or was it beige to yellow?  Please describe any larger rocks or bedrock nearby. Any oysters or ammonites, even fragmental, might help.  If you are comfortable PMing me more precise provenance, we can nail down formation w more certainty.
