Today it is known that similar teeth are found in juvenile specimens of "Daspletosaurus", and it is likely that teeth referred to "Aublysodon" came from that genus. In October 2000, the type specimen of "Aublysodon" went missing when being sent by registered mail from the Academy of Natural Sciences of Philadelphia to the Field Museum of Natural History. Because of the presence of "Aublysodon"-type teeth in other juvenile tyrannosaurines than "Daspletosaurus", such as those of "Tyrannosaurus", remains of which can also be found in Montana, Thomas Carr no longer considered the name to represent a real biological taxon, but to be a "nomen dubium".
