...Karl T. Bates; Roger B. J. Benson; Peter L. Falkingham Abstract We investigate whether musculoskeletal anatomy and three-dimensional (3-D) body proportions were modified during the evolution of large (>6000 kg) body size in Allosauroidea (Dinosauria: Theropoda). Three adaptations for maintaining...

... cladistic analyses that place Monolophosaurus in a more derived position within Allosauroidea. We review the Middle Jurassic record of Chinese theropods and compare Monolophosaurus to other Middle Jurassic theropods globally. These comparisons suggest that Monolophosaurus and Chuandongocoelurus formed...

... of both Allosauroidea and Spinosauroidea by numerical phylogenetic analyses. Redescription of the type material of C. tashuikouensis reveals an unusual combination of morphological features that render determination of its systematic position problematic. It possesses anatomical features that have been...

Scored as a lateral tooth, it was placed among Ceratosauria, as the basal-most taxon of the clades Berberosaurus  + Ceratosauridae or Abelisauroidea, among Megalosauroidea, closely related to Monolophosaurus or Sciurumimus , or as the basal-most Allosauroidea...

... but not most likely to be correct based on the available data (Ceratosauridae, Abelisauridae, basal Allosauroidea). We note that all three analyses find similarities with Dromaeosauridae, and the PCA indicates strong similarity with Megalosauridae and some tyrannosauroids. We suggest here that GLAHM 125390a...

... theropod guilds in Asiamerica is still not understood. The disappearance of previous apex theropod clades such as Spinosauridae and Allosauroidea between the Turonian and the Campanian may be due to out-competition by the newly evolved Tyrannosauridae, loss of the primary prey of these older taxa, or other...
