Data from: Patagonian Eocene Archaeopithecidae Ameghino, 1897 (Notoungulata): systematic revision, phylogeny and biostratigraphy
The Archaeopithecidae is a very poorly known group of native ungulates from the Eocene of Patagonia (Argentina), whose alpha taxonomy has remained obscure since Ameghino's times. It is traditionally considered as a family representative of the Casamayoran (middle Eocene) South American Land Mammal Age and it is thought to be morphologically close to the notopithecids. After studying more than 200 specimens from several institutions, including all the type specimens, a taxonomic overestimation is established. Out of the six species considered originally as archaeopithecids, Archaeopithecus rogeri is here recognized as the only valid name and species; subsequent synonymies are proposed and previous taxonomic hypotheses discarded. This exhaustive revision has permitted improving the knowledge of A. rogeri and, for the first time, it has revealed many craniodental characters which allow amending its diagnosis and differentiating this taxon from other Eocene notoungulates. Archaeopithecus rogeri is a small-sized taxon characterized by its complete and rooted dentition, which is relatively higher than that of other contemporaneous short-crowned notoungulates and shows ontogenetic variation in size and morphology. The body mass range of A. rogeri (1.4–2.5 kg) is comparable to those of notopithecids and some small hegetotheriids. The phylogenetic analysis shows A. rogeri is not directly related to any family within Notoungulata, appearing into a polytomy, as a basal taxon of typotherians. The biochronological range of A. rogeri is adjusted to Vacan (middle Eocene) through the Barrancan subages (late middle Eocene); older (Riochican, late early Eocene) and younger (Mustersan, late Eocene) records remain to be confirmed.

FIGURE 1 in A new species of Trachytherus (Notoungulata: Mesotheriidae) from the late Oligocene (Deseadan) of Southern Peru and the middle latitude diversification of early diverging mesotheriids
FIGURE 1. Map of South America showing the approximate locations of sites that have yielded remains of Oligocene mesotheriids: stars are to indicate locations of undescribed/unclassified Tinguirirican mesotheriid materials; octagons indicate the widely dispersed, Deseadan Trachytherus spegazzinianus; and diamonds indicate localities containing all other recognized species of Trachytherus (Deseadan). The dashed oval circumscribes the area we refer to as the "Bolivian Oroclinal Region," an area that contains all four recognized species of Trachytherus (see text for details). Background map modified from NASA image.
FIGURE 7 in A new species of Trachytherus (Notoungulata: Mesotheriidae) from the late Oligocene (Deseadan) of Southern Peru and the middle latitude diversification of early diverging mesotheriids
FIGURE 7. Phylogeny and historical biogeography of the Mesotheriidae. Cladograms of A and B were based upon the phylogenetic analysis in this study for the early diverging, non-mesotheriine mesotheriids (without the Deltran optimization given fig. 6) combined with the analysis of Croft et al. (2004) for the Mesotheriinae (see also Flynn et al. 2003). That of A includes the "published mesotheriid" (PM) dataset only, whereas B, the "undescribed plus published mesotheriids (U+PM), includes undescribed Tinguirirican material. Question marks indicate the uncertainties of affinities of the Tinguirirican taxa and that of an indeterminate mesotheriine Colhuehuapian (see text). Lines from taxon to map of South America are to indicate the general region(s) from which the taxa are known. The reconstructions of ancestral area presented here are based on the single character coding strategy (see Material and Methods). The bold lines of the cladogram indicate the evolution of the BOR distribution on the tree, whereas thin stems indicate distribution in SSA (see text for comments).
