Papers and Beyond

Staurikosaurus headlines a chapter in an older edition of the book The Dinosauria. This chapter has been replaced in newer editions of the book, but the importance of Staurikosaurus and the many papers discussing the anatomy and the phylogeny of Staurikosaurus remain in the newly re-designated chapters. These include the papers that initially described the holotype fossil (Colbert 1970) and estimates of missing elements of the skeleton (Grillo and Azevedo, 2011b) as well as those that ask questions about the origin of saurischian dinosaurs and Staurikosaurus' placement in this discussion (e.g. Galton, 2000). Staurikosaurus continues to be studied beyond the skeleton and its phylogenetic importance to the evolution of dinosaurs also. Grillo and Azevedo (2011a) studied the pelvis and hindlimb to describe the state of the musculature in these areas. These papers should be plenty for a day's reading, so enjoy learning more about the anatomy of Staurikosaurus and where this dinosaur sits in the dinosaur family tree!
