LordTrilobite Posted September 15, 2018 Share Posted September 15, 2018 I came across this tooth and was wondering if the ID is correct as I haven't had much first hand experience with raptor teeth so far, especially Hell Creek raptors. It's being advertised as a Dakotaraptor steini tooth from the Hell Creek formation. In the description it says it has very fine serrations though I find them hard to spot in the photos as they are a little on the small side. It's pretty small. So could it be Acheroraptor instead?

Fossil'n'Roll Posted September 16, 2018 Share Posted September 16, 2018 At 1" it's too big for Acheroraptor and it doesn't appear to have the longitudinal ridges that Acheroraptor teeth have. It could be either Dakotaraptor or Nanotyrannus. I think you'll need a better look at the serrations to tell which it is.

LordTrilobite Posted September 16, 2018 Author Share Posted September 16, 2018 Yeah I was looking for that thread as well, but didn't find it at first. Indeed, I came to the same conclusion, Nano or Dakota, I'm fine with both, so that's good. Thanks. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Jaimin013 Posted September 16, 2018 Share Posted September 16, 2018 I've seen this as well and not a Dakotaraptor. Not to call someone out but this individuals ID'ing has been in the past all over the place. Link to comment Share on other sites More sharing options...
mburkett Posted September 17, 2018 Share Posted September 17, 2018 The photos aren’t super clear, but the serrations on the anterior and posterior carina look like they’re the same size. This indicates it’s tyrannosaurid. Dakotaraptor teeth have the typical dromaeosaurid morphology, where the posterior serrations are noticeably larger. This is a Nanotyrannus tooth Link to comment Share on other sites More sharing options...
