Kangnasaurus coetzeei Haughton, 1915 |
|
Kangnasaurus (meaning "Farm Kangnas lizard") is a genus of iguanodontian ornithopod dinosaur found in supposedly Early Cretaceous rocks of South Africa. It is known from a tooth and possibly some postcranial remains. At times, it has been considered dubious or a valid genus. It was probably similar to Dryosaurus.
Kangnasaurus was named in 1915 by Sidney H. Haughton. The type species is Kangnasaurus coetzeei. The generic name refers to the Kangnas farm; the specific name to the farmer, Coetzee. Kangnasaurus is based on holotype SAM 2732, a tooth found at a depth of 34 metres in a well at Farm Kangnas, in the Orange River valley of northern Cape Province, South Africa. The age of these rocks, conglomerates in an ancient crater lake, is unclear; they are thought to be from the Early Cretaceous. Haughton thought SAM 2732 was a tooth from the upper jaw, but Michael Cooper reidentified it as a lower jaw tooth in 1985. This had implications for its classification: Haughton thought the tooth was that of an iguanodontid, while Cooper identified it as from an animal more like Dryosaurus, a more basal ornithopod.
