-Andy- Posted March 9, 2018 Share Posted March 9, 2018 Hi all, I have a mysterious croc tooth that needs identifying. It measures 7cm in a straight line, with a crown length of 3cm. It was found in a backwater near Savannah, Georgia. It came out of an old stream bed eroding out. The area is normally a Miocene deposit where there are Gavialosuchus americanus but the original owner (who is a fossil croc expert) sincerely believes it's something else as there are supposedly earlier deposits there as well. He thinks it is from the lineage of Deinosuchus. Has anyone seen such croc/alligator teeth in Georgia? Has anyone heard of late Cretaceous deposits near Savannah? Thank you. 8 Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday!

indominus rex Posted March 9, 2018 Share Posted March 9, 2018 Deinosuchus? But don't take my word on that. But that's a monster tooth, nice find. Life started in the ocean. And so did my interest in fossils. Link to comment Share on other sites More sharing options...
HoppeHunting Posted March 9, 2018 Share Posted March 9, 2018 I’m no expert on this, but what I can say is that I think it’s more likely from a croc larger than Gavialosuchus/Thecachampsa solely based on size. This would be an abnormally large tooth from that genus. Deinosuchus seems feasible.

Troodon Posted March 9, 2018 Share Posted March 9, 2018 The geological map would argue against anything cretaceous near Savannah. I think most of that portion of the state was under water during the cretaceous How do these Gavialosuchus teeth compare to your tooth? http://blogs.cofc.edu/macebrownmuseum/2016/04/08/friday-fossil-feature-an-investi-gator-of-the-oligocene-of-south-carolina/ 6 Link to comment Share on other sites More sharing options...

I think most of that portion of the state was under water during the cretaceous. I agree. The geological maps I've seen indicate that area is far more likely of Quaternary age. If I had seen the crown by itself without locality data, I would definitely think it's a Deinosuchus. Now I am curious to see if anyone have seen these kinda tooth from non-Cretaceous deposits.

SailingAlongToo Posted March 9, 2018 Share Posted March 9, 2018 @-Andy- That is a gorgeous specimen you have there. Quite robust. It definitely looks like the Deinosuchus teeth we find in a Cretaceous lag deposit in SE NC. Mrs.SA2 and I have 15 or so in our personal collection. @Daleksec and @sixgill pete have collected the NC site and have some in their collections as well. I really can't think of anything else it could be, but I've never fossil hunted in GA, and other than Coastal Plains, I don't know much about its geology. Given what you "probably" have, the location you found it and the known geology, I believe there is definitely some scientific significance,/ importance to your find. I recommend contacting some museums and universities for their opinions. My first thought is @Boesse of course. Even though he's a whale guy he may know a good reptile person. University of Florida has really good reptile folks and there is Dr. Hastings at the VA Museum of Natural History, who is a reptile specialist (and also graduated from the U of FL program.) Keep us in the loop as you learn more on your mystery. It's very exciting! Cheers, SA2 3 Don't know much about history Don't know much biology Don't know much about science books.........

FossilDAWG Posted March 9, 2018 Share Posted March 9, 2018 I agree that @Boesse would be the person to offer an authoritative opinion. Personally I think Troodon has it with his link. The Cretaceous is deeply buried in the Savannah area, and there are no fossiliferous Cretacous exposures upriver, so despite the similarities I think Deinosuchus can be discounted. That assumes that the locality info is correct of course. Don 1 Link to comment Share on other sites More sharing options...

sixgill pete Posted March 9, 2018 Share Posted March 9, 2018 Gavialosuchus? Is it known from the Miocene / Pliocene? There are some very large croc teeth found at Lee Creek and they are Thecachampsa as far as I know. I have also seen a Thecachampsa tooth this size from the Belgrade Quarry in North Carolina. 3 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...
Boesse Posted March 10, 2018 Share Posted March 10, 2018 Hey all - this tooth certainly falls within the range of variation for Gavialosuchus. @sixgill pete - Gavialosuchus and Thecachampsa are the same animal, with some using one name over the other. Deinosuchus teeth, if memory serves, have strong longitudinal fluting. I've seen others claim to have discovered "Deinosuchus" fossils from Savannah, including a large premaxilla, but all seem to be consistent with Gavialosuchus just like we get here in Charleston.

Plax Posted March 12, 2018 Share Posted March 12, 2018 any chance the provenance could be wrong? Link to comment Share on other sites More sharing options...
Jesuslover340 Posted April 4, 2018 Share Posted April 4, 2018 Provenance is everything...especially with crocodilian/crocodylomorph teeth, as they're not specialized like mammalian teeth. A croc tooth from one area can look EXACTLY like a croc tooth from a completely different age and location and yet, be from two completely different species. About the only way you can pin down species or even genus for crocodilians is knowing the provenance and subsequently knowing the species that have been described from the location from associated material such as a skull/jaw with intact teeth. 3 "Let us therefore follow after the things which make for peace, and things wherewith one may edify another."-Romans 14:19 Link to comment Share on other sites More sharing options...

Bobby Hi @Boesse, does this look like a Cetacean tooth to you? I emailed Dr David Schwimmer, and he replied this: Interesting material, but definitely not from the Cretaceous. The isolated tooth is probably not crocodylian, but rather from a cetacean: the proportions of crown and root really don't match any I've seen, and the crown curvature is too extreme to be a posterior croc tooth. I'm not expert on Miocene whales, but I know there were a number of toothed whales and dolphins around at the time. You might check with the Calvert Museum for a better ID. I trust Dr Schwimmer in croc matters, and I would like your input as well seeing as you have experience with whales. 1 Looking forward to meeting my fellow Singaporean collectors!

Dr. Stephen J. Godfrey and the other paleo experts replied. They say it's definitely not a cetacean. They believe it's Thecachampsa which they find there. I will label it Gavialosuchus for now. 7 Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday!
