... locomotor performance at large body size, related to muscle leverage, mass, and body proportions, are tested and all are unsupported in this analysis. Predictions from 3-D musculoskeletal models of medium-sized (Allosaurus) and large-bodied (Acrocanthosaurus) allosauroids suggest that muscle leverage scaled...

F igure 3. 3-D volumetric reconstructions of Allosaurus MOR 693 (left) and Acrocanthosaurus NCSM 14345 (right) from the studies of Bates et al. (2009a , b ). These studies produced a range of volumetric models but shown here are the initial “best estimate” reconstructions (A, B) and models

F igure 5. The relationship between hip joint angle and the summed muscle moment arms for hip extension (A) and flexion (B) normalized by femoral length for Allosaurus and Acrocanthosaurus. Negative hip joint angles represent hip flexion and positive angle extension along a sagittal plane

F igure 6. 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

F igure 2. Reconstruction of pelvic and femoral muscle origins and insertions in Allosaurus (A) and Acrocanthosaurus (B) on the basis of archosaurian muscle homologies and the extant phylogenetic bracket (EPB) of extant crocodilians and birds. 3-D musculoskeletal models (not to scale

F igure 4. Normalized hip flexor-extensor moment arms for pelvic and femoral muscles in Allosaurus and Acrocanthosaurus across a range of hip joint angles. Positive hip joint angles and moment arms represent hip extension, and negative values flexion, and for size-independent comparison raw

... Cretaceous. Hu (1964) suggested that Chilantaisaurus was more derived than Allosaurus ( Antrodemus ) and Acrocanthosaurus (and therefore later in geological age). This suggestion was mainly based on the possession of a long and robust humerus, a reduced fourth trochanter and short, robust metatarsals...

... and Milner 1997 ), but this character is problematic because it has also been used to support a relationship to the carcharodontosaurid Acrocanthosaurus ( Stovall and Langston 1950 ; Sereno et al. 1996 ). The articular surfaces of the centra are transversely much wider than tall in Sigilmassasaurus...

Like other bones of the forelimbs, manual phalanges show a wide range of variability. Whereas the length of the second phalanx...

... affinities are uncertain. In sum, the presence of a basally branching titanosauriform ( Sonorasaurus ), cf. 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...

Contrastingly, in more primitive theropods such as Ceratosaurus (UMNH VP 5278), Dilophosaurus (UCMP 37302) and Piatnitzkysaurus (PVL 4078), the ventral surface of the axial intercentrum is horizontal.
