-Andy- Posted February 21, 2016 Share Posted February 21, 2016 Hi all, I have a set of three lovely reptilian teeth from Barbour and Russell Counties of Alabama that I need help identifying. First up, the large mosasaur tooth. The size and general shape of this points to Tylosaurus, Second, the smaller mosasaur tooth. The size and shape points either to Platecarpus or Clidastes propython. I can't decide. Third, the croc. As far as I know, Deinosuchus and Bottosaurus are the only crocs from this area. The tooth looks like Bottosaurus to me. I'm unfamiliar with teeth from this locality, so I'd appreciate any help in getting them identified. 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!

Troodon Posted February 21, 2016 Share Posted February 21, 2016 (edited) Your probably in the Blufftown formation with the Croc tooth given those counties. Here are some images of Deinosuchus teeth from that locality. Bottosaurus's range was further east in South Carolina and of Maastrichtian age. These localities are Santonian to Campanian. Edit By the way great teeth from AL, don't see them that nice to often. On your mosasaur teeth here is an article on what has been found in AL but everything I've seen from this article and SVP journals talk about western AL and the two counties you mention are eastern AL. http://www.encyclopediaofalabama.org/article/h-2271 Edited February 21, 2016 by Troodon 2 Link to comment Share on other sites More sharing options...
JarrodB Posted February 21, 2016 Share Posted February 21, 2016 Your first tooth looks a lot like my Tylosaur teeth from Texas. Link to comment Share on other sites More sharing options...

I'll have to check with Terence(who gave me these lovely teeth) if there's any confirmed Bottosaurus teeth from that area. Here's some Bottosaurus teeth from Eastern USA which can pass for Deinosuchus. Your first tooth looks a lot like my Tylosaur teeth from Texas. I agree. Do you know which species of Tylosaur yours is? I think the last tooth is actually gator. What leads you to think it's gator? 1 Looking forward to meeting my fellow Singaporean collectors!

PaleoWilliam Posted February 23, 2016 Share Posted February 23, 2016 I think the last tooth is actually gator. I do not know what lived in Alabama but it does look like gator teeth I've seen from Florida. 1 Link to comment Share on other sites More sharing options...

Troodon Posted February 23, 2016 Share Posted February 23, 2016 (edited) Deinosuchus is in the alligatorid family... and Terence collects in the Blufftown formation Andy you can also email U of Alabama they have the best collection of Mosasaur teeth from that region http://almnh.ua.edu/ehret.html Edited February 23, 2016 by Troodon 2 Link to comment Share on other sites More sharing options...
Troodon Posted February 23, 2016 Share Posted February 23, 2016 (edited) Andy here is a older paper I found that you can access that will show you what has been found in that formation as far as Croc's and Mosasaurs. (Pg 115) Some are undescribed and the University may be your best bet. No Botto's found https://www.researchgate.net/publication/264495654_Schwimmer_D_R_Late_Cretaceous_fossils_from_the_Blufftown_Formation_Campanian_in_western_Georgia_The_Mosasaur Also found an SVP paper, page is attached which leads me to say that I would be cautious using species names from other localities. The Blufftown is Santonian in age and you can see what has identified in comparable age formations of Alabama Edited February 23, 2016 by Troodon 2 Link to comment Share on other sites More sharing options...

-Andy- Posted February 25, 2016 Author Share Posted February 25, 2016 Deinosuchus is in the alligatorid family... and Terence collects in the Blufftown formation Andy you can also email U of Alabama they have the best collection of Mosasaur teeth from that region http://almnh.ua.edu/ehret.html I emailed. Here's Dr. Dana's reply I’m not a mosasaur expert, but I asked one of recent graduates who is: The first tooth is definitely Deinosuchus. Very nice example! The second tooth is a little tougher to ID. I would lean more toward Platecarpus because of how long and thin it is and the slightly sigmoid shape of the carina... could still be Clidastes though. The third tooth is definitely Tylosaurus. Cheers, Dana I don't recall that crenulated ridge on my Deinosuchus (third pic). I have Deinosuchus teeth. Some of them do have ridges, though this one is indeed more serrated than what you'd expect. Looking forward to meeting my fellow Singaporean collectors!

Troodon Posted February 25, 2016 Share Posted February 25, 2016 Super, always good to go to local experts and see what they say. Also shows you the local fossil record is important tool to help in an ID. Link to comment Share on other sites More sharing options...

-Andy- Posted February 25, 2016 Author Share Posted February 25, 2016 so the third tooth with the crenulated edge is tylosaurus? You mean this? It's confirmed as a Deinosuchus. 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!

Plax Posted February 25, 2016 Share Posted February 25, 2016 Dana says in your post that the third tooth is definitely tylosaurus; no? Perhaps I'm reading this wrong or the pics sent aren't representative of your original post? I would think that the third tooth is a deinosuchus also by shape. My only question was concerning the crenulated ridge. Link to comment Share on other sites More sharing options...
-Andy- Posted February 26, 2016 Author Share Posted February 26, 2016 The pics I sent aren't representative of my original post. So the third tooth you're wondering about is indeed a Deinosuchus.

Plax Posted February 29, 2016 Share Posted February 29, 2016 I figured this was probably the case. thanks Link to comment Share on other sites More sharing options...
