Diadectids were the first fully herbivorous tetrapods. Although several other groups of early tetrapods independently acquired herbivory, diadectids were the only Carboniferous tetrapods that were able to process high-fiber terrestrial plants. Diadectids were also the most diverse group of herbivores, representing the first radiation of plant-eating tetrapods. Both Cope and Marsh recognized that diadectids were herbivores in 1878 when they studied their distinctively broad, cusped teeth. In his description of Diadectes, Cope mentioned, "animals belonging to this genus were, in all probability, herbivorous."
Diadectids underwent an evolutionary radiation, diversifying into thirteen species in the Late Carboniferous and Early Permian, outnumbering other diadectomorphs such as the limnoscelids. This radiation was likely the result of diadectids' expansion into a new herbivorous ecological niche that was previously unfilled. While the distribution of limnoscelids is limited to parts of North America and Tseajaia is restricted to only the southwestern United States, diadectids are present in Europe and much of North America, occupying a much wider geographic range than other diadectids.

Famous quotes containing the word diet:
“The pills are a mother, but better,
every color and as good as sour balls.
Im on a diet from death.”
—Anne Sexton (19281974)
“Newsmen believe that news is a tacitly acknowledged fourth branch of the federal system. This is why most news about government sounds as if it were federally mandatedserious, bulky and blandly worthwhile, like a high-fiber diet set in type.”

“Television programming for children need not be saccharine or insipid in order to give to violence its proper balance in the scheme of things.... But as an endless diet for the sake of excitement and sensation in stories whose plots are vehicles for killing and torture and little more, it is not healthy for young children. Unfamiliar as yet with the full story of human response, they are being misled when they are offered perversion before they have fully learned what is sound.”
—Dorothy H. Cohen (20th century)
