Placerias — size comparison — facts and sources

Placerias was a large herbivorous dicynodont of Late Triassic North America. It belonged to the synapsids, the lineage containing mammals and their extinct relatives, rather than to dinosaurs. Its remains have been found in what is now Arizona. It used plant food in ecosystems also inhabited by large predatory archosaurs and the earliest dinosaurs.

Numerous finds are associated with the history of research by the University of California Museum of Paleontology. Possible ecological similarities to hippopotamuses, including periodic use of water, are comparative hypotheses. They are not firm evidence of an everyday semi-aquatic life.
