Source-derived summary

Orretherium (meaning "Five teeth beast"; in part from the Aonikenk language) is a genus of mesungulatid mammal that lived in South America (Chile) during the Late Cretaceous period in what is now the Dorotea Formation. It is estimated to have weighed ~1.3kg.

Editorial summary

The public source identifies “Orretherium” as extinct mammal genus. This brief keeps that definition visible, then builds a research path around Orretherium, extinct and mammal.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 42-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Orretherium, extinct and mammal providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Orretherium”, the useful work is to connect “extinct mammal genus” 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 11, 2026. The linked authority identifier is Q106438122. None of the 0 selected statements returned an explicit reference.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
