Shotgun Mitogenomics Provides a Reference Phylogenetic Framework and Timescale for Living Xenarthrans
(Oxford University Press, 2016-03)
Xenarthra (armadillos, sloths, and anteaters) constitutes one of the four major clades of placental mammals. Despite their phylogenetic distinctiveness in mammals, a reference phylogeny is still lacking for the 31 described ...
Chromosome study of Anteaters (Myrmecophagideae, Xenarthra): a preliminary report
(Sociedade Brasileira de Genética, 2004-01-01)
Anteaters belong to the Order Xenarthra / Family Myrmecophagidae and are the only members without teeth. There are three genera with four living species in the family Myrmecophagidae: Myrmecophaga tridactyla (giant anteater), ...

(Universidad Nacional Autónoma de México. Centro de Geociencias, 2010-06)
Los Xenarthra (Mammalia) constituyen un grupo monofilético, caracterizado por una arquitectura esqueletaria particularmente distinta a la de los demás mamíferos placentarios. Su distribución actual es casi exclusivamente ...

Chromosome painting in three-toed sloths: a cytogenetic signature and ancestral karyotype for Xenarthra
(BIOMED CENTRAL LTDLONDON, 2012-03-19)
Background: Xenarthra (sloths, armadillos and anteaters) represent one of four currently recognized Eutherian mammal supraorders. Some phylogenomic studies point to the possibility of Xenarthra being at the base of the ...
Multi-locus sequencing reveals a novel Bartonella in mammals from the Superorder Xenarthra
(2020-09-01)
The superorder Xenarthra consists of sloths, anteaters and armadillos, mammals originated from South America and currently distributed from the south of North America to the south of South America. The present study aimed ...
The southernmost occurrence of the Aquatic Sloth Thalassocnus (mammalia, tardigrada) in two new pliocene localities in Chile
(Asociación Paleontológica Argentina, 2017)
Thalassocnus is a sloth (Mammalia, Tardigrada) adapted to an aquatic lifestyle. It was first described from the Neogene deposits of the Pisco Formation of Peru, from where most of the specimens come. The genus is represented ...
A new genus and species of Planopinae (Xenarthra: Tardigrada) from the Miocene of Santa Cruz Province, Argentina
(Magnolia Press, 2013-08)
Prepoplanops boleadorensis, a new genus and species of Planopinae (Xenarthra, Tardigrada), is described herein. The new taxon is based on a nearly complete specimen recovered from the Cerro Boleadoras Formation (Miocene, ...
The Scelidotheriinae Ameghino, 1904 (Phyllophaga, Xenarthra) from the Ensenadan-Lujanian Stage/Ages (Early Pleistocene to Early-Middle Pleistocene-Early Holocene) of Argentina
(Elsevier, 2009-12)
Review of the specimens assigned to Scelidotheriinae (Phyllophaga, Xenarthra) from the Ensenadan-Lujanian Stage/Ages of Argentina, showed that two genera are recognized for this territory: Scelidotherium (Owen) and Scelidodon ...
