Diadectes was a heavily built animal, 1.5 to 3 meters long, with a thick-boned skull, heavy vertebrae and ribs, massive limb girdles and short, robust limbs. The nature of the limbs and vertebrae clearly indicate a terrestrial animal.
It
possesses some characteristics of reptilians and amphibians, combining a
reptile-like skeleton with a more primitive, seymouriamorph-like skull.
Diadectes has been classified as a stem-amniote close to the ancestry of
amniotes.
Among its primitive features, Diadectes has a large otic notch (a feature found
in Paleozoic amphibians) with an ossified tympanum.
At the same time its teeth show advanced specializations for a herbivorous diet
that are not found in any other type of early Permian animal. The eight front
teeth are spatulate and peg-like, and served as incisors that were used to nip
off mouthfuls of vegetation. The broad blunt cheek teeth show extensive wear
associated with occlusion, and would have functioned as molars, grinding up the
food.
It also had a partial secondary palate, which meant it could chew its food and
breath at the same time, something many even more advanced reptiles were unable
to do.
