Glanosuchus
''Glanosuchus'' is a genus of scylacosaurid therocephalian from the Late Permian of South Africa. The type species ''G. macrops'' was named by Robert Broom in 1904. ''Glanosuchus'' had a middle ear structure that was intermediate between that of early therapsids and mammals. Ridges in the nasal cavity of ''Glanosuchus'' suggest it had an at least partially endothermic metabolism similar to modern mammals.
==Description==
''Glanosuchus macrops'' was first described in 1904 by South African paleontologist Robert Broom, who named the genus and species on the basis of a nearly complete holotype skull. The skull has been distorted during fossilization and the bone is indistinguishable from the surrounding matrix in some parts. In illustrating the holotype, Broom chose to reconstruct the skull of the species rather than draw the actual specimen.
The skull of ''Glanosuchus'' is about long.〔 ''Glanosuchus'' probably grew to around in length. Like other early therocephalians, ''Glanosuchus'' had a long, deep snout and large canine teeth. The incisor teeth at the front of the upper jaw are also large and blade-like. There are six incisors on either side of the upper jaw, the furthest one being noticeably smaller than the rest. Five small pointed teeth are located behind each canine. The snout is wider in the front than it is behind, a usual feature among therapsids but present in several other related therocephalians. The nostrils are positioned at the tip of the snout and directed forward.〔
