Placerias (name meaning "Broad Body") is a genus of dicynodont reptiles that originated during the Late Triassic period in what is now North America.


Era & DiscoveryEdit

Placerias lived during the Triassic period, some 225-212 MYA, living alongside the flying reptiles and the early dinosaurs. Though first discovered in 1904, fossils of forty Placerias were found near St. Johns, southeast of the Petrified Forestin Arizona. This site has become known as the 'Placerias Quarry' and was discovered in 1930, by Charles Camp and Samuel Welles, of the University of California, Berkeley. 

Physical AttributesEdit

Measuring up to 3 meters long and weighing 1-2 tones, Placerias were large and magnificent mammal-like reptilian beasts that are not at all related to dinosaurs. They are instead a much more ancient species of reptile called synapsids, distant relatives of the modern mammals and their ancestors. Before the Tirassic, there were once various different species of these powerful creatures existing across the world. But, eventually, Placerias became one of the last representatives of their kind that remained in the Late Triassic. Therefore, they had become an endangered species.

Behavior & TraitsEdit

Placerias traveled in huge migrating herds. Despite their fearsome appearance, Placerias were in fact gentle herbivores. Their tusks were used for digging up roots. However, for two angry and jousting males, these tusks could be used as lethal weapons. In the heat and dry season, Placerias spread out over scrubland to feed. When in danger, Placerias moved desperately slow.
