About listen

Doswellia is an extinct genus of archosauriform from the Late Triassic of North America. It belongs to the family Doswelliidae, which also includes the genera Archeopelta and Tarjadia from South America. Doswellia was a terrestrial carnivore that reached a length of 2 m (7 ft) and lived during the Carnian stage of the Late Triassic. It possesses many unusual features including a wide, flattened head with narrow jaws and a box-like rib cage surrounded by many rows of bony plates. The type species Doswellia kaltenbachi was named in 1980 from fossils found within the Poor Farm Member of the Falling Creek Formation in Virginia. The formation, which is found in the Taylorsville Basin, is part of the larger Newark Supergroup. Doswellia is named after Doswell, the town from which remains have been found. A second species called D. sixmilensis was described in 2012 from the Bluewater Creek Formation of the Chinle Group in New Mexico.
