Structural abnormalities in Paraguayan southern three-banded armadillos Tolypeutes matacus (Chlamyphoridae)

Xenarthra
Two structural abnormalities are reported in southern three-banded armadillos Tolypeutes matacus (Chlamyphoridae) from Paraguay. Additional reports of individuals with amputated legs are noted, and a potential explanation for the frequency of such ...

How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales

Journal of Anatomy, Volume 247, Issue 6, Page 1224-1240, December 2025.
This study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

Paleogene Glyptodontidae Propalaehoplophorinae (Mammalia, Xenarthra) in extra-Patagonian areas [PDF]

Andean Geology, 2015
Paleogene records of Cingulata Glyptodontidae are scarce. The only well described comes from the Paleogene of Argentine Patagonia. Two subfamilies have been reported for that period: Glyptatelinae and Propalaehoplophorinae. Until this contribution, the latter taxon was geographically restricted to the locality of El Pajarito (Late Oligocene, Deseadan ...

Ehrlichia spp. and Anaplasma spp. in Xenarthra mammals from Brazil, with evidence of novel ‘Candidatus Anaplasma spp.’ [PDF]

, 2020
: Anaplasmataceae agents are obligatory intracellular Gram-negative α-proteobacteria that are transmitted mostly by arthropod vectors. Although mammals of the Superorder Xenarthra (sloths, anteaters, and armadillos) have been implicated as reservoirs for

Variación no alométrica en el cráneo del perezoso bayo Bradypus variegatus (Schinz, 1825) (Mammalia, Pilosa, Bradypodidae)

Graellsia, 2019
El perezoso bayo Bradypus variegatus (Schinz, 1825) es un mamífero monomórfico, de ontogenia craneal poco conocida. En este estudio analizamos la alometría estática entre tamaño y forma, utilizando 21 especímenes diferentes de edades diversas.

Genomic Signatures in Maned Three‐Toed Sloths From Ancient to Recent Environmental Changes in Brazil's Threatened Atlantic Forest

Molecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT Environmental and climatic changes have shaped the evolutionary trajectories of natural populations, leaving genomic signatures that reflect how species respond to these shifts and their impacts on genetic health. While these insights are essential for unravelling evolutionary histories and informing conservation strategies, studies on ...

Molecular and morphological baraminology of Xenarthra

, 2023
There are 31 xenarthran species living today, made up of armadillos, anteaters, and sloths. These animals are characterized by a narrow, elongated skull and a unique vertebral process in the posterior trunk. Xenarthra represents an apobaramin within which several holobaramins may be discerned, using both mitochondrial DNA and morphological data.

Effects of Landscape Characteristics on Abundance of Giant Anteaters in Intensively Farmed Areas

Biotropica, Volume 57, Issue 6, November 2025.
In this study, we analyzed the abundance of giant anteaters in 55 landscapes within a 34,000 km2 region that has undergone significant transformation due to intensive agricultural practices, particularly the cultivation of sugarcane. In each landscape, we used three camera traps to record the presence of this species. Our occupancy models revealed that

When the giant rests: Evidence of prolonged inactivity in the giant armadillo (Priodontes maximus) of the Pantanal

Xenarthra
We documented prolonged inactivity (12 consecutive days), an uncommon behavior, in a giant armadillo (Priodontes maximus) in the Pantanal. Unlike previous observations in the Amazon, there was no internal activity or alternative exits, suggesting ...
