The skull and mandible of the Miocene hegetotheriine notoungulate Hegetotherium mirabile
are described. Although conventional models of hegetothere biology propose that these …

Teeth are generally the best-preserved elements among mammal fossil remains and are
highly diagnostic characters. Consequently, much mammalian paleontological, systematic …

ABSTRACT The late early Miocene Santa Cruz Formation of Patagonian Argentina is
remarkable for its well-preserved and diverse mammalian fauna. This study evaluates the …

The early Cenozoic witnessed the major diversification of placental mammals and large-
scale faunal turnovers as the modern mammalian fauna was established. As the dominant …

Tooth morphology and rates of wear have strong controls on how well mammals survive in
their habitats. Herbivorous mammals, specifically ungulates, combat the effects of wear …

The evolutionary history of a clade has traditionally been studied through phylogenetics, and
taxonomic diversity has been used as a crude proxy for morphological diversity. However …

Small-bodied, insectivorous Nyctitheriidae are known in the Palaeogene fossil record almost
exclusively from teeth and fragmentary jaws and have been referred to Eulipotyphla …

The morphological and ecological diversity of lemurs and lorisiformes once rivaled that of
the rest of the primate order. Here, we assemble a dataset of 3D models representing the …

Tooth counts are commonly recorded in fossil diapsid reptiles and have been used for
taxonomic and phylogenetic purposes under the assumption that differences in the number …

In this paper, we describe a new species of Hemiacodon known only from University of
Colorado Museum Loc. 92189 (Donna's Locality) in the Turtle Bluff Member of the Bridger …
