Thomas.Dodson Posted February 7, 2023 Share Posted February 7, 2023 Hello all, I have some teeth that have accumulated from some past trips that I haven't been able to find an ID for. I appreciate any input people might have. First, there is this fish tooth from the Moodys Branch Formation (Eocene) of Mississippi. As difficult as bony fish teeth are I thought I'd see if anyone could ID this one since it is quite a nice tooth. Closest thing I've found is Eutrichiurides but it isn't as compressed as figured plates. Attempting to show the double carinae. The following teeth are from the Byram Formation (Oligocene, Rupelian) of Mississippi. I figured Carcharias on this one. Link to comment Share on other sites More sharing options...
Fin Lover Posted February 7, 2023 Share Posted February 7, 2023 (edited) Maybe thresher (Alopias sp.) for the first shark tooth?

This looks like something along the Isurus (Macrorhizodus)/ Carcharodon lineage. The Rupelian ones in Europe are sometimes called Isurus flandricus.

Cheers. -Ken This also crossed my mind but I think I convinced myself early on I was seeing what I wanted to see and I pursued the fish route. That and I could find zero references for crocodilians in the Jackson Group of Mississippi. I do remember Breard and Stringer reported a "Crocodylus sp." from the Yazoo Formation in Copenhagen, Louisiana. Very cool, thanks for the input.
