dinosaur man Posted December 30, 2019 Share Posted December 30, 2019 I was searching the internet earlier today and found out that all Aublysodon teeth where that of Tyrannosaurinae juveniles. From Two medicine formation Daspletosaurus horneri, from Judith river formation and Dinosaur park formation Daspletosaurus sp., and from Hell creek and Lance formations T-rex, and so on... The study was done by Dr. Phil Currie, hope this helps with teeth like this!! Link to comment Share on other sites More sharing options...

Troodon Posted December 31, 2019 Share Posted December 31, 2019 Aublysodon was a tyrannosaurid tooth taxon only known by unserrated premaxillary teeth. It very old news but currently viewed as nomen dubium. Over the years several papers by Carr, Currie, Holtz have indicated that these teeth need to be assigned to other tyrannosaurids. There are no papers that I'm aware of that specifically states which tyrannosaurid. In fact where multiple tyrannosaurids exist, Hell Creek, Lance, Judith River, Two Medicine, Aguja etc Formations and all the units in the Belly River Group its impossible to assign them to a specific one. So only in the Horseshoe Canyon Fm can they positively be assigned to Albertosaurus. All other tyrannosaurid premaxillary teeth are indeterminate. 4 Link to comment Share on other sites More sharing options...
PaleoNoel Posted December 31, 2019 Share Posted December 31, 2019 So would my premax tooth have been classified as Aublysodon? I think when I posted it on ID a while back it was thought to most likely be Nano. (Just over a centimeter) Link to comment Share on other sites More sharing options...

Aublysodon does not exists. 1 Link to comment Share on other sites More sharing options...
