Source-derived summary

Propleopus is an extinct genus of marsupials. The genus contains three species: P. chillagoensis from the Plio-Pleistocene, and P. oscillans and P. wellingtonensis from the Pleistocene.

Discovery and naming

The type species Propleopus oscillans was first named under the genus Triclis by Charles Walter De Vis in 1888. Because the German entomologist Hermann Loew had already named the genus Triclis for a robber fly in 1851, Albert Heber Longman named a replacement name Propleopus in 1924, combining the prefix pró (πρό, 'before') with pleopus, the latter in reference to the junior synonym of Hypsiprymnodon moschatus: Pleopus nudicaudatus named by Richard Owen in 1877. In 1978 and 1985, Archer and colleagues named two more species, P. chillagoensis and P. wellingtonensis, and provided a taxonomic revision of the genus.

Description

In contrast to most other kangaroos, and similar to their small extant relative, the musky rat-kangaroo, they were probably omnivorous and quadrupedal. Propleopus is estimated to have weighed around 35.5–47.1 kilograms (78–104 lb).

Editorial summary

The public source identifies “Propleopus” as genus of marsupials (fossil). This brief keeps that definition visible, then builds a research path around Propleopus, genus and marsupials.

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—1888, 1851, 1924, 1877—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Propleopus, genus and marsupials providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Propleopus”, the useful work is to connect “genus of marsupials (fossil)” 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 Apr 13, 2026. The linked authority identifier is Q137912. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1888, 1851, 1924 and 1877.

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.
