Jonkeria (Van Hoepen, 1916) was an omnivorous dinocephalian therapsid titanosuchid from the Tapinocephalus Assemblage Zone, Lower Beaufort Group, of the South African Karoo.
Description[]
The overall length was three and a half meters or more (up to 4 or 5 meters), the skull about 55 cm long. The skull is nearly twice as long as wide, and the snout is elongated and provided with sharp incisors and large canines. The cheek teeth were rather small. The body is robustly built, and the limbs stout.
Jonkeria cannot be distinguished from its relative Titanosuchus on cranial grounds, but only in limb length; Jonkeria having short and squat limbs, and Titanosuchus long ones. About a dozen species have been named, including the type species, J. truculenta. At least some of the other species were synonymised by Boonstra 1969.
