Allosaurus Posted August 19, 2020 Share Posted August 19, 2020 Does anyone have a reference (or references) for how many and which species of crocodilians are present in the Two Medicine Formation? Was Brachychampsa present, and if so, was it the only alligatoroid in the Two Medicine to have those short, rounded teeth for crushing? Link to comment Share on other sites More sharing options...
jpc Posted August 20, 2020 Share Posted August 20, 2020 My guess is that there has not been a study on these... Did you try Google Scholar? Link to comment Share on other sites More sharing options...

Troodon Posted August 20, 2020 Share Posted August 20, 2020 Not much out there published on the TMF other than Dino. Brachychampsa was quite widespread in Campanian deposits so its reasonable to think it was in the Two Medicine Link to comment Share on other sites More sharing options...

I have a couple teeth that are similar to Brachychampsa, but they're small enough I've been avoiding trying to photograph them as I'm just not confident in being able to get sharp enough detail. I may ID them as possible Brachychampsa. Link to comment Share on other sites More sharing options...

But Brachychampsa with a question mark might do. Link to comment Share on other sites More sharing options...

Brachychampsa has been described from campanian of New Mexico up to Canada why I made that statement. Link to comment Share on other sites More sharing options...
