All xenarthrans known to date are characterized by having permanent teeth that are both high crowned and open rooted, i.e., euhypsodont, and with a type of hypsodonty different from that of the rest of Placentalia: dentine hypsodonty. Also, most xenarthrans lack enamel; however, its presence has been reported in the fossil armadillo Utaetus buccatus and in living Dasypus. Considering the divergence of Xenarthra from other eutherians that possessed enameled teeth, the absence of enamel is a… 
Dental enamel structure in long-nosed armadillos (Xenarthra: Dasypus) and its evolutionary implications
TLDR
The retention of enamel and the fact that this genus is the only living xenarthran with two functional generations of teeth support the early divergence of the Dasypus lineage among living cingulates.
Early evidence of molariform hypsodonty in a Triassic stem-mammal
TLDR
New fossils of the stem-mammal Menadon besairiei from the Late Triassic are described, which show the convergent evolution of hypsodonty before mammals and highlight the constraints imposed by limited tooth replacement and tooth wear in the evolutionary trajectories of herbivorous mammals and stem-Mammals.
A New Eocene Dasypodid with Caniniforms (Mammalia, Xenarthra, Cingulata) from Northwest Argentina
TLDR
The singularity of the morphological characteristics of these Paleogene armadillos of northwest Argentina reinforces the hypothesis of an intertropical origin of mammal clades different from those of the Paleogene in more austral regions of Argentina.
Paleogene Xenarthra and the Evolution of South American Mammals
TLDR
The derivation of numerous omnivorous and herbivorous lineages from a myrmecophagous ancestor is a curious and unique feature of xenarthran history and may be due to the peculiar ecology of the native South American mammal fauna.
Xenarthran dental microstructure and dental microwear analyses, with new data for Megatherium americanum (Megatheriidae)
TLDR
A review of the present knowledge in these 2 fields together with new results on feeding adaptations in the giant ground sloth, Megatherium americanum, and a trend that microwear patterns in extinct sloths may reflect habitat as much as the texture of ingested food.
Xenarthran Dental Microstructure and Dental Microwear Analyses, with New Data for Megatherium americanum (Megatheriidae)
Xenarthran teeth are rootless and continuously growing. They lack an outer enamel layer and consist instead of a combination of 2 generally different varieties of dentine with or without an outer
Loss of Ancient Diversity of Xenarthrans and the Value of Protecting Extant Armadillos, Sloths and Anteaters
TLDR
This contribution provides two examples of the ecological diversity of xenarthrans in the geological past that largely surpass the one the authors know today and urges that autochthony and past taxonomic richness and ecologic diversity be recognized as values for establishing conservation priorities and policies.
New Specimen of Pucatherium parvum (Xenarthra, Dasypodidae), a Singular Dasypodid of the Paleogene (Eocene) of Northwest Argentina: Importance in the Early Evolution of Armadillos
TLDR
An almost complete dorsal carapace and several postcranial remains were preserved, providing important information about this particular taxon, comparable in size to Dasypus novemcinctus, although the osteoderms are very small.
Pseudogenized Amelogenin Reveals Early Tooth Loss in True Toads (Anura: Bufonidae).
TLDR
Using selection intensity estimates and synonymous substitution rates, analysis of functional and pseudogenized AMEL resulted in an estimated inactivation window of 46-60 MYA in the lineage leading to modern true toads, a timeline that coincides with the rise of the family Bufonidae.

The teeth of the “toothless”: novelties and key innovations in the evolution of xenarthrans (Mammalia, Xenarthra)
TLDR
The combination of tooth features that characterize xenarthrans might be seen as the key innovation for the ecologic diversity developed at least since the Oligocene, breaking the mold of the tribosphenic condition that constrained the evolution of the other major clades of mammals.
Hypsodonty and enamel microstructure in the Paleocene gondwanatherian mammal Sudamerica ameghinoi
Gondwanatherians were the earliest mammals to develop hypsodont cheek-teeth with thick cementum, already by the Late Cretaceous. Hypsodonty occurred independently in Gondwanatheria and Theria;
Microstructure of dental hard tissues in fossil and recent xenarthrans (Mammalia: Folivora and Cingulata)
TLDR
An analysis of fossil and recent xenarthran dental hard tissue microstructure shows that osteodentine is not exclusive to fossil Cingulata, but also occurs in some recent taxa, and profound modifications of orthodentines architecture in comparison to other mammals are found.
Evolution of the tooth enamel microstructure in the earliest proboscideans (Mammalia)
TLDR
Thealysed microstructures suggest that the enamel ancestral morphotype of paenungulates was primitive for euth-erian mammals, consisting in radial enamel, and illustrates an unexpected early diversity of the order in Africa.
Evolutionary Implications of Dental Eruption in Dasypus (Xenarthra)
TLDR
The basal phylogenetic position of the taxon within dasypodids suggests that diphyodonty and late dental replacement represent the condition of early xenarthrans, and the inferred reduction in the number of molars to a single locus and the multiplication of premolars represent rare features for any living mammal, but may represent apomorphic characters for Dasypus.
A NEW PALEOCENE ARMADILLO (MAMMALIA, DASYPODOIDEA) FROM THE ITABORAÍ BASIN, BRAZIL
Abstract. Riostegotherium yanei is a new genus and species described on the basis of isolated osteoderms from Itaborai Basin (Brazil) of Itaboraian land-mammal age (middle Paleocene). The osteoderms
Hypsodonty in Pleistocene ground sloths
TLDR
Among Tardigrada hypsodonty is apparently affected by diet, habitat and habit, and among mylodontids, morphologic and biomechanical analyses indicate that hypsidonty was unlikely to be due solely to feeding behavior, such as grazing.
Paleogene Pseudoglyptodont Xenarthrans from Central Chile and Argentine Patagonia
TLDR
A new, large-bodied species of Pseudoglyptodon is described from volcaniclastic deposits of the Abanico ( =  Coya-Machalí) Formation of the central Chilean Andean Main Range and phylogenetic definitions of the names Phyllophaga and Tardigrada are proposed.
UNDER PRESSURE? DENTAL ADAPTATIONS TO TERMITOPHAGY AND VERMIVORY AMONG MAMMALS
TLDR
The results point to the likely involvement of this genetic pathway in the rapid, parallel morphological specializations in termitophagous and vermivorous species, and it is shown that diets or feeding mechanisms in other mammals that are linked to decreased reliance on complex can lead to similar cascades of change.
