Source-derived summary

Pareiasaurus (from Greek: pareia, "cheek" and Greek: sauros, "lizard") is an extinct genus of pareiasauromorph reptile from the Permian period. It was a typical member of its family, the pareiasaurids, which take their name from this genus.

Fossils have been found in the Beaufort Group.

Description

Pareiasaurus is a large quadruped, about 2.5 metres (8.2 ft) long, with elephantine legs, walking in a typically reptilian posture. The skull is broad and the snout short. Its skull had several spine- and wart-like protrusions. Pareiasaurus's leaf-shaped teeth, ideal for biting through tough plant fibers, indicate it was a herbivore. Even the palate had teeth.

Species

P. nasicornis (Haughton and Boonstra, 1929) is from the Tropidostoma Zone, Karoo basin, South Africa. This early form is one of the first representatives of the genus.

Editorial summary

The public source identifies “Pareiasaurus” as genus of Permian parareptiles. This brief keeps that definition visible, then builds a research path around Pareiasaurus, genus and Permian.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—1929—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Pareiasaurus, genus and Permian providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Pareiasaurus”, the useful work is to connect “genus of Permian parareptiles” to the records capable of establishing context and consequence.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 3, 2026. The linked authority identifier is Q967742. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1929.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
