Titanosuchidae is an extinct family of dinocephalians known only from the middle Permian Tapinocephalus Assemblage Zone of South Africa.[1]
The titanosuchids were large, omnivorous[2] or herbivorous[1] animals. As with other tapinocephalians, they had thickened skulls that may have been used in head-butting, but to a lesser degree than in Tapinocephalidae or Anteosauridae. They had large canine teeth, strong incisors with a "talon and heel" morphology, and leaf-shaped postcanine teeth. Two titanosuchid genera are recognized as valid: Jonkeria and Titanosuchus; they can be distinguished on the basis of limb proportions.[1]
