Jonkeria spp. Temporal range: Capitanian, 265–260Ma Scientific classification Kingdom: Animalia Phylum: Chordata Clade: Synapsida Order: Therapsida Suborder: †Dinocephalia Family: †Titanosuchidae Genus: †Jonkeria Species:
Jonkeria was a very large omnivorous (although there is some dispute to this - e.g. Colbert 1969 p. 136) dinocephalian, from the Tapinocephalus Assemblage Zone, Lower Beaufort Group, of the South African Karroo. Description The overall length was 3.5 metres (11 ft) or more (up to 4 or 5 metres (13 or 16 ft)), 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. According to Boonstra 1969 p. 38, 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. Classification 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. There has been no recent review of the genus. ![]() Credit goes to DiBgd for the above illustration. Edited by Taipan, Apr 27 2014, 09:56 PM.
