gturner333 Posted November 25, 2018 Share Posted November 25, 2018 I found this theropod tooth in some Lance Formation material. I believe it is a dromaeosaur tooth, but was wondering if it is fairly complete or just the tip. The serrations get smaller toward the base and the curvature of the tooth seems to be curving back toward the base. What do you think? Hash marks are 1mm. Thanks.

JoeS Posted November 25, 2018 Share Posted November 25, 2018 hi, looks like nearly complete and beautiful Troodon tooth, only the very tip is missing. nice one! Link to comment Share on other sites More sharing options...
JoeS Posted November 25, 2018 Share Posted November 25, 2018 judging from the shape of the denticles Pectinodon bakkeri - anyone? 2 Link to comment Share on other sites More sharing options...
gturner333 Posted November 25, 2018 Author Share Posted November 25, 2018 That’s even better. I didn’t have any Troodon teeth. The Pectinodon bakkeri looks like a good match, too. Any seconds to that motion? Link to comment Share on other sites More sharing options...
Jaimin013 Posted November 25, 2018 Share Posted November 25, 2018 Pectinodon bakkeri not a Troodon tooth however a fantastic tooth even with that small bit of tip missing! This post is helpful in identifying teeth like this: 2 Link to comment Share on other sites More sharing options...

One of the characteristics of Pectinodon teeth is the appearance of only a single row of denticles. Beautiful tooth! 1 Link to comment Share on other sites More sharing options...

gturner333 Posted November 25, 2018 Author Share Posted November 25, 2018 Ok, this may be the cause of my confusion. Correct me if i’m wrong. Troodon and Pectinodon are different genus but from the same Troodontidae family. Link to comment Share on other sites More sharing options...

Troodon and Pectinodon are different genus but from the same Troodontidae family. Based on the literature extant, I think you are correct. I am not aware of any recent revision in classification as pertains to the Troodontidae. However I am not nearly as familiar with possible recent reinterpretations regarding Pectinodon, as some members of the forum certainly will be.

bcfossilcollector Posted November 25, 2018 Share Posted November 25, 2018 Troodon’s dissertation on the topic linked via Jaimin013 is very informative. Link to comment Share on other sites More sharing options...
jpc Posted November 26, 2018 Share Posted November 26, 2018 These things were originally called Troodon by Estes, but are now known as Pectinodon. Hence the confusion. Beautiful tooth. Also not common. I have only found a few in my decades of Lance Fm collecting, including screenwashing for micros. Great find. 1 Link to comment Share on other sites More sharing options...
