Parringtonia [SEP] parent taxon
Parringtonia
Parringtonia is an extinct genus of Triassic archosaur within the family Erpetosuchidae, known from the type species Parringtonia gracilis. It is known from a single specimen, NHMUK R8646, found from the Anisian-age Manda Formation of Tanzania. This specimen, like most archosaur material from the Manda Formation, is fragmentary, including only a maxilla and a few postcranial bones. They show similarities with those of another archosaur called "Erpetosuchus", known from the Middle Triassic of Scotland and the eastern United States. The phylogenetic placement of
more. Unlike "Erpetosuchus", "Parringtonia" has a foramen or hole on the outer surface of the maxilla. The scapula of "Parringtonia" differs in that it has a small bump or tubercle over its shoulder socket. Both "Parringtonia" and "Erpetosuchus" have a groove that runs along the top of the neural arch of each vertebra.
Classification and phylogeny.
