Owenetta kitchingorum

Ownetta kitchingourm, an Owenetta species.

Owenettidae is an extinct family of anapsid procolophonian parareptiles. Fossils have been found primarily from Africa, with one genus present from South America. It is the sister taxon to the family Procolophonidae. The family was constructed in 1939 for the type genus Owenetta. Since then several other genera have been assigned to Owenettidae, including Barasaurus and Saurodektes.

Barasaurus-skeleton

Barasaurus's skeleton. It was a owenettid reptile genus.

The oldest known owenettid, Owenetta rubidgei, dates back to the Wuchiapingian stage of the Late Permian. It and two other owenettids, Barasaurus and Saurodektes, have been found from the Beaufort Group in the Karoo Basin of South Africa. These strata span the Permo-Triassic boundary and provide evidence for the great faunal change that occurred as a result of the Permian–Triassic extinction event. Although most owenettids lived during the Permian, remains of some taxa such as "Owenetta" kitchingorum (soon to be placed within its own genus) extend the temporal range of the family into the Triassic. The youngest known owenettid is Candelaria from the Santa Maria Formation of Brazil, which lived during the Ladinian stage of the Middle Triassic. Owenettids were relatively small procolophonians that possessed broad heads and robust bodies. The family shares several synapomorphies that separate it from other related procolophonomorphs. The absence of an entepicondylar foramen is diagnostic to all members from which the humerus is known. In regards to cranial anatomy, there is no contact between the postorbital and parietal bones as a result of enlarged postfrontal bones, and the skull table is formed partly from large supratemporals lateral to the parietal bones.
