[1] Arctotraversodon plemmyrodon was originally classified as a species of Scalenodontoides, but was given its own genus in 1992.

[4] It is closely related to Exaeretodon and Siriusgnathus,[5] but is distinguished by the presence of a shelf-like expansion of its parietal called the nuchal table.

[7] Paleoecology At the time this species lived, there was a single continent called Pangea.

Melanorosaurus, a primitive sauropodomorph, was discovered along with Scalenodontoides in Elliot Formation in Lesotho.

[3] Although an omnivore, the dinosaur was unlikely to pose a threat to it due to the large size of the cynodont.
