Extinct crocodyliforms from the age of dinosaurs (Mesozoic Era) display an impressive range
of skeletal morphologies, suggesting a diversity of ecological roles not found in living …

We describe a new taxon of mylodontid sloth from the late Oligocene (Deseadan South
American Land Mammal “age”), Salla Beds of Bolivia. This taxon, Paroctodontotherium …

Living crocodylomorphs have an ossified secondary palate with a posteriorly positioned
choana that enables their semi‐aquatic, predatory ecology. In contrast, the earliest …

The trilophodont gomphothere group is a monophyletic group of genera separated from
other proboscideans by one synapomorphy, the presence of trefoil‐shaped wear patterns on …

Throughout the Jurassic, a plethora of marine reptiles dominated ocean waters, including

Dolichocebus is known from the type skull encased in a concretion, numerous isolated teeth,
parts of two mandibles, and a talus. The specimens come from the Trelew Member (early …

The shape and arrangement of cusps and crests and the orientation of wear striations on the
cheek teeth of fossil mammals can be used to reconstruct occlusal patterns. Occlusal …

The ecology, and particularly the diet, of treeshrews (order Scandentia) is poorly understood
compared to that of their close relatives, the primates. This stems partially from treeshrews …

The Chalicotheriidae are extinct, large, claw-bearing Perissodactyls. There are two
subfamilies, the Chalicotheriinae and the Schizotheriinae. These are discerned by the more …
