Source-derived summary

Chenanisaurus (meaning "Sidi Chennane lizard") is a genus of theropod dinosaur that lived during the Late Cretaceous in what is now Morocco. The genus belongs to the family Abelisauridae. It is known from a partial dentary (lower jawbone) and several teeth that were found in the phosphate mines of Khouribga, in rocks of the Maastrichtian-aged Ouled Abdoun Basin. Chenanisaurus was described in 2017 by British paleontologist Nicholas Longrich and colleagues. The genus contains a single species, Chenanisaurus barbaricus.

Chenanisaurus is one of few known African members of Abelisauridae. Its length is estimated to be around 7–8 m (23–26 ft), making it among the largest known abelisaurids. The dentary of Chenanisaurus is distinct in that it was deep and slightly bowed. The outer surface is ornamented with deep striations, grooves, and rugosities, as in related forms such as Majungasaurus.

Chenanisaurus was among the last non-avian dinosaurs, existing just one million years prior to the Cretaceous–Paleogene extinction event.

Editorial summary

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

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—2017—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Chenanisaurus, genus and reptiles providing the first useful test.
Editorial analysis

Why this record matters

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

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 18, 2026. The linked authority identifier is Q29052716. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2017.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. 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.
