Rowboater Posted March 10, 2023 Share Posted March 10, 2023 Recent finds. February may be a bit warmer than March? I have two twisted teeth with large bases, which I think could be upper cowshark (but only one point?) and several small makos, plus "the usual" sand tiger, angel shark, drum "teeth", and gray shark. Always good to get out! 3 Link to comment Share on other sites More sharing options...
MarcoSr Posted March 11, 2023 Share Posted March 11, 2023 That one twisted tooth is very interesting. Could you post some closeup individual pictures of it? It is probably a pathologic upper cowshark tooth as you stated in your post. Marco Sr. "Any day that you can fossil hunt is a great day."

Rowboater Posted March 14, 2023 Author Share Posted March 14, 2023 @MarcoSr Sorry for the delay (scanner/printer issues). Not sure any of the scans below improve on the first. Odd that none of the three recent "upper cowshark" teeth have even a hint of a second point. One that I was sure was a cow shark seems to have been tipped since I found it, it also had lost much of its root (now just a nondescript tooth). The much bigger one can stand on its huge root, by far biggest of my upper cowshark teeth. Link to comment Share on other sites More sharing options...

The top two teeth (I don't think the bottom tooth is the same, just broken upper tooth) are cowshark, most likely Notorynchus cepedianus, upper symphyseal/parasymphyseal teeth. These teeth usually only have a main crown without any cusplets. See the below extant Notorynchus cepedianus jaw from elasmo.com. Marco Sr. 3 "Any day that you can fossil hunt is a great day."
