Cranial Anatomy and Variation of Prosaurolophus maximus (Dinosauria: Hadrosauridae)McGarrity, Christopher Thomas 14 December 2011 (has links)
Prosaurolophus maximus is a crested hadrosaurine known from numerous specimens from the Dinosaur Park Formation of Alberta. Therefore, it is an ideal taxon to reconstruct patterns of growth and variation in hadrosaurids, and improve our understanding of their evolutionary relationships. This study describes the cranial anatomy of P. maximus, quantitatively examines its range of variation, and provides the first ontogenetic series for this taxon. A second species, P. blackfeetensis, was named based on morphological differences in the characteristic nasal crest; however, morphometric results fail to quantitatively differentiate P. blackfeetensis from P. maximus. A species-level phylogenetic analysis of hadrosaurids recovers P. maximus and P. blackfeetensis as sister taxa. Based on both the morphometric and phylogenetic data, this study supports the previous hypothesis that P. blackfeetensis is a junior synonym of P. maximus thereby substantially increasing its temporal range, and suggests a long period of morphological stasis in this taxon.
