Paranthodon is a sparsely known genus of the bird's pelvis dinosaur from the stegosauria group .
So far only parts of the skull including some teeth are known of Paranthodon . The snout shows the typical elongated shape of the Stegosauria, but is characterized by a unique, rearward-directed extension of the intermaxillary bone (premaxillary). The triangular teeth, which are relatively small, as in all stegosaurs, are similar in structure to those of Kentrosaurus , which suggests a relationship with it. Nothing is known about the rest of the body structure of this dinosaur.
The finds come from the Kirkwood Formation in the South African province of Eastern Cape and are dated to the early Lower Cretaceous ( Berriasian ) to an age of around 145 to 139 million years. The only recognized species is P. africanus . The animal was first described by the well-known South African paleontologist Robert Broom as Palaeoscincus , it was later reclassified to the genus Paranthodon .
Besides the well-known Kentrosaurus, Paranthodon is the only known representative of the stegosauria from Africa.
