Prehistoric Models: “Pelycosaurs”

Pelyocosaurs, pronounced pel-ih-ko-sor-us is an imformal group of basal or primitive synapsids (incorrectly called “mammal like reptiles”) from the late Paleozoic Era. Pelycosaurs were formerly classified in their own order, but like the name “mammal like reptiles” have fallen out of favor in modern scientific publications. Primarily due to the understanding that they are no longer considered reptiles at all. To see my model/toys click here.
