New interatheres (Mammalia, Notoungulata) from the Late Oligocene Salla beds of Bolivia
Journal of Paleontology, 2008Two new Deseadan interatheriine genera (Interatheriidae, Notoungulata) from the late Oligocene Salla Beds of BOLIVIA are described. Both are monotypic and one is known from a partial skeleton, a rarity among known pre-Santacrucian interathere taxa. Phylogenetically, both taxa nest well within Interatheriinae, showing characteristically bilobed p3-4 ...

Until the discovery of the genus Punahyrax (Geste Formation) in different localities of Catamarca and Salta provinces, “archaeohyracids” were unknown in northwestern Argentina. Here we analyze the record of these notoungulates in the region through specimens known for the Geste Formation and new remains recovered from the lower levels of the Quebrada

The first application of the mesowear method to endemic South American ungulates (Notoungulata)
Palaeogeography, Palaeoclimatology, Palaeoecology, 2008Abstract Notoungulates were the most diverse and abundant clade of endemic South American ungulates, present in nearly all Tertiary faunas. Hypsodont dentitions evolved in several notoungulate lineages by the early Oligocene, and by the middle Miocene, four families were characterized by hypselodont (ever-growing) cheek teeth.

New late oligocene Hegetotheriidae (Mammalia, Notoungulata) from Salla, Bolivia
Journal of Vertebrate Paleontology, 2005The diverse fauna from Salla, western Bolivia, represents a rare glimpse into the evolutionary history of Tertiary South American mammals outside of Patagonia (Argentina). The Hegetotheriidae (Notoungulata) from the Deseadan of Salla are composed of two taxa, a new genus and species and a species of Prohegetotherium. Sallatherium altiplanense gen.
