dc.description.abstractThe skull of Scelidosaurus harrisonii is described. Scelidosaurus is an early (late Sinemurian) armoured ornithischian dinosaur from Charmouth, Dorset. It is the first largely complete and articulated dinosaur ever discovered. Much of the exterior of the skull has a textured patina of exostotic bone that anchored keratinous scales. A small edentulous beak precedes a row of five premaxillary teeth, and there would have been a minimum of 22 maxillary teeth and 27 dentary teeth in the largest known individuals. Tooth wear is discontinuous along the dentition and jaw action appears to have been tightly constrained. There is no physical evidence of a predentary but its existence is inferred from the structure of the dentary. A sclerotic ring was present. A prominent supraorbital brow ridge overhangs the orbital cavity. A crater-shaped osteoderm is attached to the lateral surface of the postorbital. Paired osteodermal horns project dorsally from the occiput, and long bladed styloid bones project obliquely from the posterior of the skull. The nasal chambers are roofed by epivomers that are unique to this taxon. A vertical, conical epipterygoid is attached to the pterygoid. A deep pit on the posterior surface of the quadrate suggests the existence of remnant cranial pneumatism.
