Bone guy Posted September 23, 2018 Share Posted September 23, 2018 Good morning everyone. Could anyone help me ID this tooth? Because it has me stumped. Unfortunately I still have to learn lots before I can ID these ceratopsian teeth (morphologicaly they can be tricky). My first guess was cf. Leptoceratops gracilis because of the tooth's small size, it's only just over half an inch. But now I'm reconsidering this guess because maybe it's a juvenile Triceratops tooth? The lack of a root makes this tricky because I know Triceratops teeth have two roots while Leptoceratops teeth have only one. Plus the highly pronounced verticals ridge is making me lean towards Triceratops once more. Any ideas? Thank you! 1 Link to comment Share on other sites More sharing options...
Bobby Rico Posted September 23, 2018 Share Posted September 23, 2018 Hi I can’t really help but I did crop them for you to get a closer look I hope you don’t mind. 2 Link to comment Share on other sites More sharing options...

Bone guy Posted September 23, 2018 Author Share Posted September 23, 2018 Thank you @Bobby Rico that helps quite a bit! This tooth was found in the hell creek formation. Brussett, North Montana. @Troodon I've been comparing this tooth to the Leptoceratops and Triceratops teeth in your collection (thank you for making a consolidation post of your collection, I'm a new collector of dino material and the information you provide is priceless). What I'm finding is interesting. Leptoceratops teeth have multiple verticals ridges almost like a Thescelosaurus maxillary tooth, most of the trike teeth I've been comparing to totally lack those verticals ridges. If you look look at the tooth I have, it has those multiple ridges. 2 Link to comment Share on other sites More sharing options...
Runner64 Posted September 23, 2018 Share Posted September 23, 2018 Looks like Leptoceratops to me. Lepto teeth only have the one root coming out of the tooth while trike teeth split off and have two roots. 2 Link to comment Share on other sites More sharing options...
gigantoraptor Posted September 23, 2018 Share Posted September 23, 2018 Leptoceratops has not (yet) been described from the Hell Creek formation. The only described ceratopsians in this formation are Triceratops horridus, Triceratops porosus en Torosaurus latus. However, there are teeth in the Hell Creek formation that are identical to Leptoceratops gracilis. Maybe label it like cf Leptoceratops gracilis. 1 Link to comment Share on other sites More sharing options...
KimTexan Posted September 23, 2018 Share Posted September 23, 2018 Unfortunately, last I knew Troodon has been inactive for almost 3 weeks now. To my knowledge no one has heard from him or knows his whereabouts. I hope we haven’t lost him. Link to comment Share on other sites More sharing options...

He should be back soon, hopefully with some nice fossils and stories to share. 3 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."
