Mtskinner Posted December 20, 2014 Share Posted December 20, 2014 (edited) How do you go about figuring out what species croc/gator these came from? All were found in southeast Alabama. This first one is right at 1-3/4" long and 9/16" wide. Edited December 20, 2014 by Mtskinner Link to comment Share on other sites More sharing options...
Mtskinner Posted December 20, 2014 Author Share Posted December 20, 2014 Here's the 2nd one, its 2" long and 3/4" wide. Link to comment Share on other sites More sharing options...

Troodon Posted December 20, 2014 Share Posted December 20, 2014 Im no expert on croc's but could be Deinosuchus rugosus Link to comment Share on other sites More sharing options...
Shellseeker Posted December 20, 2014 Share Posted December 20, 2014 I am always tentative in differentiating gator from croc teeth. Here is an interesting link. http://www.paleodirect.com/mv10-011.htm Here are some (likely incorrect) -- 1) Striation lines are horizontal on gators and vertical on crocs 2) Croc teeth are curved to an extent that gator are not 3) Croc teeth are larger than gator teeth Tooth in post #3 is gator, post #1 is likely croc. The other 2 could be either. The american crocodile is named Gavialosuchus Americanus. A complete skull with teeth was found in Bone Valley Florida.

Paleoc Posted December 27, 2014 Share Posted December 27, 2014 The very heavy striations tend to indicate Deinosuchus. Here are some (likely incorrect) -- 1) Striation lines are horizontal on gators and vertical on crocs No. My modern alligator teeth (and the fossils) are vertically striated. 2) Croc teeth are curved to an extent that gator are not Depends on the tooth location and species. Not always a consistent rule of thumb. 3) Croc teeth are larger than gator teeth And that depends entirely on the size of the particular gator or croc. I have fossil alligator teeth from Florida which are larger than all my other croc teeth and all but my larger Deinosuchus teeth (which is actually an Alligatoroid vice a Crocodile).. And much of the data in the link you provided is incorrect as well. Gavialosuchus is not a member of Gavialidae and thus not closely related. Crocodiles have not remained unchanged since the Cretaceous anymore than Sharks are identical to ones living in the Cretaceous. And Gavials (Gavialis gangeticus) do not live in salt water. 1 Link to comment Share on other sites More sharing options...
Shellseeker Posted December 29, 2014 Share Posted December 29, 2014 Paleoc, Thanks for correcting the numerous inaccuracies and providing the true expertise for which TFF is known. I have learned much about Croc and gator teeth.

Mtskinner Posted December 29, 2014 Author Share Posted December 29, 2014 (edited) Thanks for the info guys! I'm thinking the first two teeth I posted are Deinosuchus and the last one is Leidyosuchus but the two smaller tips I'm still unsure of.
