TNCollector Posted October 16, 2017 Share Posted October 16, 2017 Here is a tooth that I recently found at a Late Cretaceous site in North Mississippi, in the Coon Creek Formation. I really don't know what to think of it, except that it appears to have some sort of enamel. I haven't seen anything similar before, so I am asking for some extra opinions! Most material at this site is marine, but the occasional terrestrial botanicals and fragmentary dinosaur remains do poke up around North Mississippi. The tooth is roughly 3/4 cm. Of course, I am always hoping for dinosaur! @Troodon And teeth are his namesake! @Al Dente Front of tooth (my reference point is kind of arbitrary). I apologize for the matrix still on it, it is very tough and I don't want to damage the tooth. Back of Tooth Chewing surface Link to comment Share on other sites More sharing options...
Troodon Posted October 16, 2017 Share Posted October 16, 2017 Looks like a possible Myledaphus sp. tooth. It's a bit encrusted 3 Link to comment Share on other sites More sharing options...
Miocene_Mason Posted October 16, 2017 Share Posted October 16, 2017 Found a similar one in bone valley matrix from @joshuajbelanger, I called it rhynchobatus sp. those are only known from Eocene on though, so Troodons probably got it right.

TNCollector Posted October 16, 2017 Author Share Posted October 16, 2017 Yeah I think that's it. Much less pretty than the other ones I have found in MS. Thanks fellas! Link to comment Share on other sites More sharing options...
Al Dente Posted October 16, 2017 Share Posted October 16, 2017 It looks like Rhombodus to me. 1 Link to comment Share on other sites More sharing options...
Plax Posted October 16, 2017 Share Posted October 16, 2017 + one Rhombodus. Would the wrinkles make it Rhombodus binkhorsti? 1 Link to comment Share on other sites More sharing options...
sixgill pete Posted October 16, 2017 Share Posted October 16, 2017 I agree with Rhombodus also. And as Plax said with the wrinkles I see, R. binkhorsti. 1 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...

Nice little tooth. Glad someone found something! I hate just sending out matrix, it's so hit and miss. I've gone through some with abundant fossils, and some with barely any. I would hate to have the reputation of sending out bumscoop matrix! Cheers Link to comment Share on other sites More sharing options...

I'm still going through (I'm very meticulous with microfossils) and I've got a little case with quite a few sharks teeth and such (even a Gastropod)from it! “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
jpc Posted November 2, 2017 Share Posted November 2, 2017 I don't know anything about Rhombodus, but our Cretaceous ray teeth out here are all Myledaphis. Looks like it to me. Your third photo is looking directly at the split root. Link to comment Share on other sites More sharing options...
Al Dente Posted November 2, 2017 Share Posted November 2, 2017 Myledaphis and Rhombodus look similar but Myledaphis is found in stream deposits while Rhombodus was marine. Link to comment Share on other sites More sharing options...
