The lower deciduous dentition of protodidelphids (Mammalia, Marsupialia) from the Itaboraí Basin (lower Eocene), Brazil, and the validity of “Riolestes capricornicus” (Goin et al., 2009)

The Anatomical Record, EarlyView.
Abstract The Itaboraí Basin, Southeastern Brazil, preserved one of the most diverse mammalian faunas from the Paleogene, with Metatheria comprising more than 60% of its diversity. Among identified metatherian clades, it has been argued that Paucituberculata is represented by “Riolestes capricornicus”.

Serologic evidence of the exposure of small mammals to spotted-fever Rickettsia and Rickettsia bellii in Minas Gerais, Brazil

Journal of Infection in Developing Countries, 2016
Introduction: Sources of pathogenic Rickettsia in wildlife are largely unknown in Brazil. In this work, potential tick vectors and seroreactivity of small mammals against four spotted-fever group Rickettsia (R. rickettsii, R. parkeri, R.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

The Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

The MacBrain Resource Center (MBRC) rhesus macaque postnatal brain histology datasets: Enabling new discoveries through NHP tissue and digital data Repositories

Journal of Anatomy, EarlyView.
The MacBrain Resource Center (MBRC) postnatal rhesus macaque brain histology datasets are organized into Collections that promote cost‐effective de novo research. This article provides examples from Collections 5, 6, and 7 and describes the histo‐ and immunohistochemical (IHC) processing of materials for Collection 6.

From sagittal to sprawled: Clavicular co‐option and the evolution of forelimb mechanics in talpines

Journal of Anatomy, EarlyView.
Forelimb posture in Eulipotyphla divides into sagittal and sprawled groups with distinct scapular and clavicular orientations. First true rib strength scales with body mass, reflecting vertical ground reaction forces, whereas clavicular strength reflects differences in medially directed forces on the pectoral girdle, especially pronounced in highly ...

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, Volume 309, Issue 10, Page 2873-2896, October 2026.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, Volume 309, Issue 9, Page 2315-2330, September 2026.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...
