(Backward flowing tooth).
Named By: Joseph Leidy - 1868.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda, Tyrannosauroidea, Tyrannosauridae, Aublysodontinae.
Species: A. mirandus (type). Also the species A. lateralis, A. grandis, A. amplus and A. cristatus are sometimes mentioned but these are considered to be highly dubious.
Size: Uncertain due to incomplete fossil material.
Known locations: USA, Montana - Judith River Group.
Time period: Late Cretaceous.
Fossil representation: Teeth.
is quite surprising when you think about how Aublysodon
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
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.
