A new middle Miocene hegetotheriid (Notoungulata: Typotheria) and a phylogeny of the Hegetotheriidae
Journal of Vertebrate Paleontology, 2006Abstract A new species of hegetotheriid notoungulate, Hemihegetotherium trilobus, is described from the middle Miocene (Laventan SALMA) Quebrada Honda Fauna of southern Bolivia. It differs from all previously described hegetotheriines in possessing a distinctly trilobed m3, a character state previously recorded only in pachyrukhine hegetotheriids.

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.
