Diadectes

Extinct genus of tetrapods

Diadectes (meaning crosswise-biter) is an extinct genus of large reptiliomorphs that lived during the early Permian period (Artinskian-Kungurian stages of the Cisuralian epoch, between 290 and 272 million years ago). Diadectes was one of the first herbivorous tetrapods, and also one of the first fully terrestrial vertebrates to attain large size.
