...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...

RMA log-log regression plots for FL against F4T. Regression lines are shown for the whole data set (i.e., Allosauroidea) and for the two taxonomic subgroups (non-carcharodontosaurians and carcharodontosaurians). The RMA regression line for Allosauroidea shows positive allometry, but 95% confidence intervals of the slope include isometry (slope 1.2773 ± 0.297, Supplementary Table 3).

... 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...

Trunk center-of-mass (CM) predictions for allosauroids and selected coelurosaurs from computer generated volumetric models. The plausible range of trunk CM positions predicted for Allosaurus MOR 693 (A) and Acrocanthosaurus NCSM 14345 (B) are nearly identical and are closely clustered together in front and below the hip joint. C, Normalizing data using femoral length demonstrates that predictions for additional allosauroid taxa from other studies plot within the ranges for Allosaurus and Acrocanthosaurus, with the exception of Henderson and Snively's (2003) reconstruction of Acrocanthosaurus (see text for discussion). Overall this suggests the magnitude of soft tissue uncertainties means it is difficult to test the hypothesis of a CM shift within Allosauroidea. However, the cranial shift in CM predictions in coelosaurs (Tyrannosaurus, Struthiomimus) suggests it is possible to identify differences and trends across larger clades within Theropoda, despite this ambiguity in the size and geometry of soft tissues.
