Possible Deinosuchus schwimmeri tooth.

Recommended Posts

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.

Deinosuchus from the eastern US usually have fluted crowns. This one is pretty smooth. I think this might be a different species of croc.

From Schwimmer 2010 publication from the Blufftown Fm.   Fig 2 & 12 references them as  posterior teeth

Also appears that Deinosuchus is not yet formally described from the Blufftown Fm

It looks quite similar to these however...

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.

I would wonder if that tooth is from Eocene or other earlier deposits which can be found in nearby counties given the excellent preservation.

It looks similar to this Thecachampsa tooth, also from Georgia.-http://www.thefossilforum.com/index.php?/topic/82649-unknown-large-croc-tooth-from-georgia/

Stewart County is home to Blufftown Formation outcrops with an extensive Cretaceous (Campanian) vertebrate fauna, including a mix of marine and nearshore/coastal species including Deinosuchus.

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.

Thanks for the excellent replies guys... I have several Thecachampsa americana teeth in my collection and this one does not look like a match.

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.

It is still a very nice crocodile tooth. Really is!
