Joeri_R Posted November 8, 2019 Share Posted November 8, 2019 Hello, I bought this small tooth for 65€. It is labeled as Deltadromeus agilis but since a skull is still unknown i doubt this. I still bought it cause it is well preserved and the serrated edges are beautiful. I would label it "abelisaurid spec. indet." Or maybe a juvenile carcharodontosaurid? I'm curios for opinions.

Compy Posted November 8, 2019 Share Posted November 8, 2019 Can you give us the size of the tooth and a serration count of both sides for 5mm? At the moment I would agree with you on abelisaurid... 1 Link to comment Share on other sites More sharing options...

Compy Posted November 8, 2019 Share Posted November 8, 2019 (edited) Sorry, I was too unspecific. I meant: How many denticles can you count over a length of 5mm? *edit: Sorry, I was too late. You don't have to count anymore, Troodon has confirmed the ID and in my opinion he is one of THE experts here...

Does a certain amount of serrations within 5mm point to a certain determination? And yes, Troodon is a great expert and as a total newbie I try to read a lot of his replies and posts. Very educating, i learn a lot Link to comment Share on other sites More sharing options...
Troodon Posted November 8, 2019 Share Posted November 8, 2019 There are a number of characteristics that help in the identification of a tooth. Serration density is one and it's best measured at the center of both the carinas at a width of 5mm for larger teeth. Unfortunately we know very little of the KK theropods and with limited material published have little to compare against. Typically Abelsaurid teeth from the KK the profile is enough since its distinctive. 3 Link to comment Share on other sites More sharing options...
