What is "diasparactus"

Diasparactus is an extinct genus of diadectid amphibians, a group quite closely related to the amniotes, and paralleling some of their features. Like all advanced diadectids, Diasparactus was a herbivore, though not as large as its more well known cousin, the Diadectes.

In Diasparactus, the spines of the dorsal vertebrae are higher than in other genera in the family.
