lesofprimus Posted February 24, 2023 Share Posted February 24, 2023 I purchased this rooted Alligatoroid tooth measuring 2.54" which was found in the Blufftown Formation on the Chattahoochee River in Stewart County, Georgia. I've been told it is a Deinosuchus schwimmeri tooth, and after some basic searching, it seems like a positive conclusion. However, I'm hoping some more knowledgeable than myself can confirm this. 1 Link to comment Share on other sites More sharing options...
Al Dente Posted February 24, 2023 Share Posted February 24, 2023 Deinosuchus from the eastern US usually have fluted crowns. This one is pretty smooth. I think this might be a different species of croc. 2 2 Link to comment Share on other sites More sharing options...

It isn't the best picture but it still looks more fluted than your specimen. Some of the lack of fluting is probably due to the fact that this specimen looks quite worn; Your specimen is in good condition. The Deinosuchus I have seen from the Blufftown in Georgia/Alabama are all very fluted. I'd agree with Al Dente and Troodon. 1 Link to comment Share on other sites More sharing options...
Troodon Posted February 25, 2023 Share Posted February 25, 2023 I would wonder if that tooth is from Eocene or other earlier deposits which can be found in nearby counties given the excellent preservation. 1 Link to comment Share on other sites More sharing options...

Don Agree but the evidence argues against the tooth from being Blufftown Fm. Morphology of tooth does not match and that it was found on a river says it could have been transported to that county. 1 Link to comment Share on other sites More sharing options...
lesofprimus Posted February 26, 2023 Author Share Posted February 26, 2023 Thanks for the excellent replies guys... I have several Thecachampsa americana teeth in my collection and this one does not look like a match. Link to comment Share on other sites More sharing options...
JorisVV Posted June 21 Share Posted June 21 It also does not match Deinosuchus. So this would be just indeterminate croc/gator tooth. It simply does not have the same morphology. This is an actual Deinosuchus Schwimmeri tooth (this one is from NC, black creek). But would rule under the same "species" as you mentioned. Yet yours is totally different than this one, or the other known individual specimens from the region. Link to comment Share on other sites More sharing options...
JorisVV Posted June 21 Share Posted June 21 It is still a very nice crocodile tooth. Really is! Link to comment Share on other sites More sharing options...
