Predictions from 3-D musculoskeletal models of medium-sized (Allosaurus) and large-bodied (Acrocanthosaurus) allosauroids suggest that muscle leverage scaled...

This suggestion was mainly based on the possession of a long and robust humerus, a reduced fourth trochanter and short, robust metatarsals...

Abstract Successional changes are recorded among saurischian dinosaur faunas throughout the Cretaceous of the Neuquén Basin. Both sauropod and theropod lineages present in NW Patagonia show comparable transformations and indicate that some clades did not survive the Late Turonian boundary. Similar patterns of changes are observed in other Patagonian sedimentary basins. Diplodocoid sauropods and carcharodontosaurid theropods are not yet recorded in levels younger than Turonian, while titanosaurians and abelisauroids are present before and after this period. Important floral changes during the mid-Cretaceous, mainly related to the proliferation of angiosperms, could be one element that influenced some dinosaurian associations.

Tenontosaurus , and a carcharodontosaurine theropod (similar to Acrocanthosaurus ) suggests that the dinosaur fauna of the Turney Ranch Formation was similar to that of other middle Cretaceous...
