ONE OF A KIND PERMIAN MATERIAL! With a fearsome jaw and reptilian appearance, Dimetrodon is often mistaken for a dinosaur. However, this family of Early Permian Age species falls into a disparate taxonomic clade known as synapsids which includes mammals. This specimen is a one of a kind, 20.2", full dorsal Dimetrodon fossil vertebra. The purpose of the spine sail is unknown, though speculation ranges from thermoregulation to sexual dimorphism, and perhaps even locomotion.
