Opossums are the most diverse and ecologically important group of New World marsupials,
although only the Virginia opossum is familiar to North American residents. In fact, many …

A comparative analysis of the forelimb myology of two neotropical procyonids (Nasua nasua
and Procyon cancrivorus) was performed to assess how observed differences in their …

Procyonids were the first carnivorans that arrived from North America to South America
during the late Miocene, before the full emergence of the Panama Isthmus. In South …

The oldest record of a carnivoran mammal in South America corresponds to the extinct
procyonid Cyonasua (late Miocene–early Pleistocene). Up to now, this genus was recorded …

Body mass estimations for extinct taxa are fundamental in palaeobiological reconstructions,
but little work has been done on this topic for non-mammaliaform cynodonts (NMC), the …

Extant procyonids only inhabit the Americas and are represented by six genera (Procyon,
Nasua, Nasuella, Bassaricyon, Potos, and Bassariscus); all of them, except Bassariscus, are …

An exquisitely preserved male skeleton of an early arctoid, Eoarctos vorax new genus and
species, provides a unique window into the origin and early divergence of Carnivora …

Caviomorph rodents have presented an astonishing size variation both in the past and
present times. The objective of this work is to estimate the body mass of 32 extinct …

It was once thought that the endemic carnivorous mammals of South America, the
metatherian sparassodonts, were driven extinct by North American carnivorans through …

This paper provides a detailed description and the functional anatomy of the forelimb of an
early Oligocene genet-sized arctoid carnivoran, Amphicynodon leptorhynchus, to infer its …
