Astegotherium supports a recent hypothesis based on molecular data that enamel loss occurred independently not only within xenarthrans but also within dasypodid armadillos, and is therefore likely representative of ancestral cingulates and xenarthans generally.

It is demonstrated that the early evolutionary history of Octodontoidea was characterized by the differentiation of successive lineages that survived until the early or middle Miocene, with no direct relationships with modern Octodontidae and Echimyidae.

This study suggests a single species occurs in this formation that cannot be separated at the genus level from Huayquerian species, and supports the model of capybara dental ontogeny and evolution and encourages revision of the whole family according to this model.

Adaptive diversity of incisor enamel microstructure in South American burrowing rodents (family Ctenomyidae, Caviomorpha)

Results suggest increased frequency of incisor use for digging in †Eucelophorus, which could be related to a more extreme tooth-digging strategy and/or occupancy of hard soils, and higher external index values as recurring patterns in distant clades of tooth‐digging rodents support an adaptive significance of this enamel trait.

It is expected that the hystricognath pioneer(s) who have colonized South America from Africa sometime during the middle Eocene, most probably had incisors that displayed a multiserial enamel with an interprismatic matrix arrangement characterizing the sub type 1 (or subtype 1 + the subtype 2 and/or the transitional 1–2) of multiseria HSB.
Late Miocene Capybaras from Argentina: Skull Anatomy, Taxonomy, Evolution, and Biochronology

The systematic interpretation of Late Miocene capybaras suggests that the early radiation of this group was not as explosive as previously thought, and was likely constrained by the early acquisition of large size, increasing complexity of the cheek teeth, and probably semi-aquatic habits.
