Theriodontia: Introduction

Part of the Vertebrate Paleobiology and Paleoanthropology book series (VERT)

Abstract

Theriodonts include three major clades: Gorgonopsia, Therocephalia, and Cynodontia (including Mammalia). The monophyly of Eutheriodontia (Therocephalia+Cynodontia) is well supported, but the association of Gorgonopsia with these groups requires further testing. Gorgonopsians in general require extensive revision, and no phylogeny of the clade currently exists. This section introduces two advances in gorgonopsian research: a redescription and review of the earliest known gorgonopsians from the Middle Permian of South Africa and a redescription of an exceptionally complete gorgonopsian from the Late Permian of Tanzania. New data on the Middle Triassic bauriid therocephalians from southern Africa, including three-dimensional morphometric comparisons, is introduced. Two cynodont studies are included, one reviewing herbivorous traversodontid cynodonts and presenting a new phylogeny, and one redescribing the problematic traversodontid “Scalenodonhirschsoni.
