Elginia was a pareiasaur; a member of a group of Late Permian parareptiles which may have grown up to 3 metres (9.8 ft).
Elginia was a dwarf genus of pareiasaur, only about 60 centimetres (2 ft) long, with fossils found at Elgin in Scotland. Elginia is known only from a single skull, which is about 15 cm long, triangular, coarsely sculptured, and armed with a number of paired bosses or spines, with the longest pair growing out of the back of the skull. These spikes were probably used for display rather than physical combat. The upper jaw bears 12 pairs of teeth, each with 9 or 10 cusps. The teeth are slightly constricted at the base and serrated at the crown.
