Notochampsa

Notochampsa is an extinct genus of protosuchian crocodylomorph.[1] Fossils have been found from the lower Clarens Formation of the Karoo Supergroup in South Africa, dating back to the Early Jurassic.[2][3][4]

Taxonomy

The genus was named in a paper published in 1904 by Robert Broom.[5] The type species was named N. istedana, and a second species, named N. longipes, was also described. Later in 1924, N. longipes was given its own genus, Erythrochampsa.[6] In that paper, Sidney Haughton created the family Notochampsidae for Notochampsa. Notochampsa was later used to include other genera of protosuchians such as Dyoplax, Pedeticosaurus, Platyognathus, and Protosuchus,[7] and later Microchampsa and Orthosuchus.[8] Notochampsa had also once been assigned to the suborder Sphenosuchia.[9]
