Show Summary Details


This chapter discusses the anatomy, evolution, biogeography, taphonomy, paleoecology, and paleobiology of prosauropaud dinosaurs. Prosauropods have been found on all the major continents, including Antarctica. They were medium- to large-sized, bipedal, facultatively bipedal or quadrupedal sauropodomorphs with long necks and tails. Prosauropods were probably the slowest of the bipedal dinosaurs but better runners than most other quadrupedal dinosaurs. Among prosauropods, Saturnalia and Thecodontosaurus are considered fully bipedal. Riojasaurus and other melanorosaurids were fully quadrupedal and the remaining prosauropods were probably only facultatively bipedal.
