From the Big Bang to the Present,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 “.” ..

enlarged, procumbent anterior lower teeth are interpreted as two incisors and a canine. Analysis of postcanine wear facets indicates that the power stroke of the lower teeth was entirely in a posterior direction, including a slightly downward and backward grinding movement at the end of the stroke.

phyletic Gomphodontosuchinae is recovered, as suggested by previous analyses. The distribution of traversodontids is discussed, with Gondwana and especially Africa suggested as the ancestral area for Gomphodontia and Traversodontidae.
