Troodon Posted July 2, 2022 Share Posted July 2, 2022 There are no theropods described from the ISALO IIIb Formation basically everything is indeterminate. . A 2005 paper by Cau et al. tries to describes some morphologies that can be assigned to a group, family or are indet. I can try to see if your teeth can be described to one of those Morphs but will need lots of information on each especially serration density on both carina and more photos as indicated in the illustration. No guarantees. So if you are interested please provide me ALL the following: Final thought do you have a location where these were found? Are you sure they are from that deposit? The issue I have with material from Madagascar is the accuracy of the provenance that they were sold under. Link to comment Share on other sites More sharing options...
