shel67 Posted September 5, 2018 Share Posted September 5, 2018 I carefully dug this very small tooth from the wall of the North Sulphur River in Ladonia, Texas. A few people have determined that it is not a mosasaur tooth. It has a straight root and the tooth is rounded and not flattened like a typical shark tooth. Any help on this little guy would be appreciated! 3 Link to comment Share on other sites More sharing options...

Ramo Posted September 6, 2018 Share Posted September 6, 2018 That is unusual. It might just be some type of fish tooth, or maybe something much more rare. Hopefully Marco Sr. takes a look at it.

There are lots of different striated reptile teeth from the Cretaceous. The tooth doesn't look like croc to me. Someone who really knows the striated Cretaceous fish and reptile teeth would need to comment like @non-remanié or @Carl. From the size it might be one of the flying reptiles. Maybe @Auspex can comment on that? Marco Sr. 1 "Any day that you can fossil hunt is a great day."

JarrodB Posted September 7, 2018 Share Posted September 7, 2018 Normally I can help on ID but I'm not sure on this one. Even my buddy Mick who has hunted the area for 10 yrs is not sure. I think it's some sort of fish. 1 Link to comment Share on other sites More sharing options...

ynot Posted September 7, 2018 Share Posted September 7, 2018 All I can say is it does not have the cross section I would expect from a rostral spineIt looks like it has 2 carnie (cutting edge).

Heteromorph Posted September 7, 2018 Share Posted September 7, 2018 Tiny Enchodus tooth? Enchodus has two carnie. EDIT: The more I look at it, I only see one cutting edge, so not Enchodus. Link to comment Share on other sites More sharing options...

siteseer Posted September 12, 2018 Share Posted September 12, 2018 The specimen looks like it's worn more like a tooth than a spine. I don't think it's a sawfish rostral spine because those have smooth enameloid. I don't think it's a sawshark rostral spine. There were sawsharks then but they are found in deepwater environments and their spines, while they can exhibit folds, tend not to be to the degree seen in the given specimen. The root doesn't look right for it either. I can't rule that out because late Cretaceous sawshark specimens are rarely found. It's so small I would tend to rule out marine reptile but what about a pterygoidal tooth of something like Platycarpus - maybe a juvenile. It is tempting just to say it's a weird fish tooth. I would ask Bruce Welton or Jean-Pierre Biddle. 1 Link to comment Share on other sites More sharing options...
