Compy Posted November 6, 2019 Share Posted November 6, 2019 Because it was the first time for me to see some teeth from the Hell Creek Form. in Montana here in Germany at our local fair (and I am quite at the beginning with my collection of dino teeth) I purchased the following teeth. According to the seller both are from the "Hell Creek Form., Badlands, Carter County, Montana". The first tooth is labeled as "Thescelosaurus garbanii". Is this correct and how can the teeth of T. garbanii and T. neglectus be distinguished? Link to comment Share on other sites More sharing options...
Compy Posted November 6, 2019 Author Share Posted November 6, 2019 The second tooth is labeled as "Pachycephalosaurus wyomingensis". I have to admit that it looks like similar labelled teeth of this species but I have too little experience to be 100% sure... Link to comment Share on other sites More sharing options...
Runner64 Posted November 6, 2019 Share Posted November 6, 2019 Both look like Thescelosaurus teeth. The second one would be a maxillary tooth and the first would be a worn pre-max tooth. Thescelosaurus teeth often get confused for Pachycephalosaurus. However, Pachycephalosaurus teeth should have a pinch in the middle which I am not really seeing in your tooth. 2 Link to comment Share on other sites More sharing options...
Troodon Posted November 6, 2019 Share Posted November 6, 2019 Agree and the proper identification for this species and the only one in the Hell Creek FM is T. neglectus 4 Link to comment Share on other sites More sharing options...
Compy Posted November 7, 2019 Author Share Posted November 7, 2019 Thank you very much @Runner64 and @Troodon. Indeed both teeth lack an pinch in the middle. Now I know what to look for to distinguish both species. Link to comment Share on other sites More sharing options...
