). The anterolateral process is slender. The parietal foramen lies in about the mid-length of the anterior half of the parietal plate. The most distinctive feature of the dorsal surface of the parietal are two dorsolateral crests. The crests run in anterolateral-posteromedial direction. The anterior end of each crest gradually diminishes and terminates on the dorsal surface of the anterolateral process. The posterior ends of the dorsolateral crests meet in the median plane. The crests, together with the anterior margin of the parietal, limit a triangular field containing the parietal foramen. The surface bears several low mounds and more or less long ridges running along the medial margins of the dorsolateral crests. From the junction of the dorsolateral crests, a median crest extends posteriorly. The length of the crest increases with the size of the parietal and it seems that this increase in length comes to the negative expense of the midline length of the anterior triangular surface, which gradually throughout ontogeny becomes proportionally shorter.This can be demonstrated by comparing the largest known parietal of this species (the one figured by

The triangular field is a space between the posteriormost portions of the dorsolateral crests. The triangular field achieves its largest width posteriorly; its posterior end is the posteromedian margin of the parietal table (

). The anterior margin of the parietal fossa lies at the level (or posterior to the level in large specimens) of the junctions of the anterolateral margins of the supratemporal processes with the parietal table. The ventral cranial crest is low and runs immediately medially to the lateral margin of the parietal. Its posterior end is turned posteromedially. The length of the juxtaotic and postfoveal crests is about the same. The posterior portion of the postfoveal crest runs immedi- ately laterally to the medial margin of the basal portion of the supratemporal process.
