Placerias

(pronounced pluh-SEHR-ree-us) Placerias was a herding dicynodont (a so-called "mammal-like reptile") that lived during the late Triassic period, roughly 222 to 215 million years ago. It was not a dinosaur.

Diet: This thick-set, hippo-like herbivore (plant-eater) ate roots and low-lying plants, like ferns, club mosses, etc.

Anatomy: Placerias was a quadruped (it walked on four legs) with short legs, a short neck, and a bulky body. It had sturdy, downward-pointing tusks (two thick, pointed canine teeth) and a toothless beak that it may have used to root in the soil and obtain food on desert-like plains or in the dry season. Placerias was up to 11.5 ft (3.5 m) long and weighed about 1 ton.

Fossils: Fossils have been found in the USA, including over 40 P. gigas fossils found at the Petrified Forest National Park, near St Johns, Arizona [the site was first excavated in the 1920's by Charles Lewis Camp (1893-1975)].
