Jurassicbro238 Posted February 14, 2023 Share Posted February 14, 2023 Hello, I recently bought a couple of spinosaurid teeth from the Kem Kem. I noticed one of them had serrations and I wanted to make sure it would still be considered a spinosaurid tooth. I've read over a really cool post by Troodon that helped me differentiate with the teeth from this area. There are some raised ridges on both sides which leads me to think its a spino. However, the serrations run on both sides of the tooth as well, although the distal serrations are much smaller in size, and I'm not entirely sure if spinosaurid serrations are shaped the way they are on this tooth. I tried getting a close up of them with my phone but I can get some closer ones if necessary. Thanks Link to comment Share on other sites More sharing options...
Kikokuryu Posted February 14, 2023 Share Posted February 14, 2023 I think it's a ziphodont croc tooth, especially with the blunt tip. 1 Link to comment Share on other sites More sharing options...
Nanosaurus Posted February 14, 2023 Share Posted February 14, 2023 Agreed, I'm getting croc vibes... Link to comment Share on other sites More sharing options...
Troodon Posted February 14, 2023 Share Posted February 14, 2023 Agree I think that's an Croc possibly Elosuchus. If there are any features on Spinosaurid carinae they are what Hendrickx calls beaded so it's not a true serration. 1 Link to comment Share on other sites More sharing options...
Jurassicbro238 Posted February 14, 2023 Author Share Posted February 14, 2023 (edited) Wow not what I was expecting but still pretty cool! Wasn't aware some crocs had serrations. Any good papers to read up on crocodilian diversity? Is Elosuchus the only crocodilian with serrated teeth?
