John in Utah Posted May 28, 2022 Share Posted May 28, 2022 Found this in the Chinle Formation outside Moab, Utah. About 3/4" (19mm) long and 1/4" (6mm) wide at the base 1 Link to comment Share on other sites More sharing options...
JBkansas Posted May 28, 2022 Share Posted May 28, 2022 Looks like a tooth, can you get a close up pic of the base and are there bumps on front or back edge? Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted May 28, 2022 Share Posted May 28, 2022 Phytosaur, maybe? 1 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
John in Utah Posted May 29, 2022 Author Share Posted May 29, 2022 Not serrated on the edges from what I can see. Some more photos below, can't really see the base unfortunately Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 29, 2022 Share Posted May 29, 2022 Not sure phytosaurs had carinae, or serrations. Looks similar to Google images of phytosaur teeth.

Troodon Posted May 29, 2022 Share Posted May 29, 2022 Isolated triassic teeth can be very hard to ID because of the similarity between them. Heckert describes phytosaur teeth into four types caniniform, serrated, unserrated and blade. Unserrated ones are fluted with ridges extending from the base to tip which does appear to be what you have. Not a lot of real experts around especially online sites. My suggestion is to contact Heckert directly and get his opinion, I've attached his info. https://earth.appstate.edu/faculty-staff/dr-andrew-b-heckert 2 Link to comment Share on other sites More sharing options...
John in Utah Posted May 30, 2022 Author Share Posted May 30, 2022 Thanks everyone for all the help, I'm learning a lot. This site is close to home so I plan to go back and look some more. Here are some photos of other interesting rocks I saw. 1 Link to comment Share on other sites More sharing options...

jdp Posted May 30, 2022 Share Posted May 30, 2022 That matrix looks a lot like the Chinle in southwest Colorado, a local unit called the "saurian conglomerate." Might even be the same unit depending where you are in Utah. Nice tooth, I'd agree this is probably phytosaur but there are so many new weird reptiles in the Chinle that it's really hard to know for sure. Additionally, the more northern parts of the Chinle are much more poorly known than the New Mexico and Arizona deposits. As others have said, Andy Heckert might be able to steer you in the right direction taxon-wise. 1 Link to comment Share on other sites More sharing options...
