The Speeding Carno Posted June 8, 2017 Share Posted June 8, 2017 Hello, I was was searching for ceratosaurus teeth for sale when I stumbled upon this tooth. There was no specific ID and I was wondering if TFF could help me ID it properly before I make a move. I was rather intrigued by it. Length: 3mm Time: Late Jurassic Location: Morrison Formation Bone Cabin Quarry Albany County, WY, USA Link to comment Share on other sites More sharing options...

Troodon Posted June 8, 2017 Share Posted June 8, 2017 Interesting tooth. Are their any additional pictures just curious what the other side looks like and if there are serrations on the mesial edge. Anyway I would call it Theropod indet. on something this small with all the theropods choices in the Morisson. Its unclear to me if this is an unformed germ tooth or infant. It would be a nice purchase just a cool tooth to display. 5 Link to comment Share on other sites More sharing options...

Other views/angles would be cool just to satisfy my personal curiosity. @Troodon could it be a tooth from one of the smaller raptor species? We find those from time to time in late Cretaceous exposures in SE NC. On the East Coast it's take what you can find since we don't have the diversity like out west. Just curious. 1 Don't know much about history Don't know much biology Don't know much about science books.........

The tooth is 3mm hard to say much from that size. Not an expert on raptors but I always equate them to dromaeosaurid type dinos that really came into their own in the cretaceous. The Morisson had a bunch of different Coelurosaurs running around could easily be one of them. 2 Link to comment Share on other sites More sharing options...

Troodon Posted June 8, 2017 Share Posted June 8, 2017 I'm not sure I would characterize the online tooth as having grooves looks more like a single recess. I would not call that tooth Ceratosaurus based on that, all examples I've seen like those in the photos provided have multiple deep grooves, again my opinion. Actually looks more like an Abelisaurid with that straight distal side. Similarly the small tooth looks more like preservation issues than grooves. 2 Link to comment Share on other sites More sharing options...
zekky Posted June 8, 2017 Share Posted June 8, 2017 I don't think it's the Troodontid that exists in the Morrison. Their teeth had serrations that hooked up. Strangely enough small theropods in the Morrison are not understood all that well. Coelurus/Tanycolagreus/Ornthilostes are not well described to the public. Plus there are not really any described very small theropods. I would stick with Theropod as the label, still mysteries in the Morrison to be solved. 1 Link to comment Share on other sites More sharing options...
The Speeding Carno Posted June 8, 2017 Author Share Posted June 8, 2017 (edited) Ok, perhaps in the future I'll be able to find a match when we finally understand the smaller theropods of the Morrison. Thanks for your information everyone! Sadly, there are no additional pictures. Edited June 8, 2017 by The Speeding Carno 1 Link to comment Share on other sites More sharing options...
