Fossil'n'Roll Posted April 25, 2019 Share Posted April 25, 2019 I just found this little tooth for sale. It is from the Hell Creek Formation in Montana and is 5/16" long. Assuming that includes the fake root, by measuring on my screen it appears to actually be 3/16" long along the distal edge. Serrations then are about 9 per 1/16" distal and 13.5 per 1/16" mesial and look more rod-like than chisel-like to me. There are no ridges on the sides, so it's not Acheroraptor. Could it be Dakotaraptor? This species has been #1 on my list for a while and I would love to have this in my collection if it is Dakotaraptor.

Troodon Posted April 25, 2019 Share Posted April 25, 2019 It could be DR but without a clean base cannot be certain. It has some of the characteristics of one. 1 Link to comment Share on other sites More sharing options...
Fossil'n'Roll Posted April 25, 2019 Author Share Posted April 25, 2019 Thanks, not sure if I want a maybe. I'll have to think about it. Here is another view. What's needed for a sure ID is distance from the base of the mesial carina to the gumline, right? Sadly that appears to be either not preserved or covered up.

Troodon Posted April 25, 2019 Share Posted April 25, 2019 I hate to say it is without a good look of the shape of the base and a full mesial carina. Link to comment Share on other sites More sharing options...
Fossil'n'Roll Posted April 26, 2019 Author Share Posted April 26, 2019 I will pass on this one and will keep looking for a better one. In the meantime, I'll keep learning. I just read (and bookmarked) this post. Excellent info. Thanks again! Link to comment Share on other sites More sharing options...
