Valgipes
genus of extinct mammals
Valgipes is an extinct genus of scelidotheriid ground sloth, endemic to intertropical Brazil and Uruguay during the Late Pleistocene. Thought to have been a forest-dwelling browser, Valgipes is a monotypic genus with a complex and long taxonomic history, and is a close relative of Catonyx and Proscelidodon.
Taxonomy
The taxonomic history of Scelidotheriidae in Brazil is convoluted, and only one species of Valgipes, V. bucklandi, is recognised today, named in honour of William Buckland. Based on the remains of 23 individuals discovered in Lagoa Santa, Minas Gerais, in 1846 Peter Wilhelm Lund described two Brazilian scelidotheriids, Scelidotherium owenii and Scelidotherium bucklandi, while Winge (1915) named them as Scelidotherium magnum and Catonyx giganteus. In 1874, Paul Gervais erected the genus Valgipes for a different species, V. deformis, which he based on a calcaneum bone which he classified as scelidotheriid. Based on comparison of the heel bone with that of Megalonyx, in 1954 Robert Hoffstetter considered that the calcaneum came from an unusual member of the family Megalonychidae, a convention followed by later palaeontologists (although the species was declared incertae sedis in 1979) until the material was studied in further detail, leading to V. deformis and S. bucklandi being combined as Valgipes bucklandi by Cartelle et al. (2009). The only other valid scelidotheriid known from Brazil is Catonyx cuvieri. Valgipes is differentiated from Catonyx based on dentition and postcranial morphology.
Below is a phylogenetic tree of the Scelidotheriinae, based on the work of Nieto et al.
This brief starts where responsible research should: with the source description of “Valgipes” as genus of extinct mammals. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of extinct mammals. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q30326631. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1846, 1915, 1874 and 1954.
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.
