Archaeosyodon praeventor, a titanosuchid.
Titanosuchidae is a family of dinocephalian therapsids. They appeared in the Middle Permian. They had large canine teeth, and their incisors were very strong. Titanosuchids are related to other dinocephalians, such as Tapinocephalidae - a group that includes Moschops. The only described titanosuchids are Jonkeria and Titanosuchus. Like all other dinocephalians, they went extinct in the Permian-Triassic extinction.
