In Depth

       It‭ ‬is quite surprising when you think about how‭ ‬Aublysodon is represented in so many dinosaur books and internet sources even though back when it was described in‭ ‬1868‭ ‬it was only from teeth.‭ ‬Still this was a sign of the times back then with other discoveries such as Troodon,‭ ‬which was also named by Joseph Leidy,‭ ‬also‭ ‬initially‭ ‬only being described from their teeth.

       Aside from the type specimens,‭ ‬further teeth have been attributed to Aublysodon and given separate species.‭ ‬However further study of these specimens has revealed that they probably belong to other tyrannosaur genera,‭ ‬possibly juvenile individuals of Tyrannosaurus.‭ ‬Partial skulls and post cranial remains have also in the past been attributed to Aublysodon,‭ ‬but upon more detailed study have been found to probably belong to Daspletosaurus.‭

       The future for Aublysodon as a distinct genus of dinosaur is highly uncertain because not only is it difficult to attribute remains to this genus,‭ ‬the original holotype specimen is now lost to science.‭ ‬This makes it impossible to re-examine the holotype to confirm if Aublysodon should remain its own genus.
