1.1 Characteristics
became the first European hadrosaurid to have its endocast and inner ear CT-scanned and reconstructed in 3D. The structure of the inner ear can dictate the movement of the eyes and head while the brain cavity can yield information to tie its owner to a particular subfamily.
The largest known specimen (NCSM 14345) is estimated to have measured 11.5 m (38 ft) from snout to tail tip and weighed 5.7 t (6.3 short tons) to 6.2 t (6.8 short tons), with an upper maximum weight of 7.25 t (7.99 short tons) within the realm of possibility for this specimen . The skull of Acrocanthosaurus , like most other allosauroids , was long, low and narrow . The lacrimal and postorbital bones met to form a thick brow over the eye, as seen in carcharodontosaurids and the unrelated abelisaurids . Acrocanthosaurus and Giganotosaurus shared a thick horizontal ridge on the outside surface of the surangular bone of the lower jaw, underneath the articulation with the skull . The most notable feature of Acrocanthosaurus was its row of tall neural spines, located on the vertebrae of the neck, back, hips and upper tail, which could be more than 2.5 times the height of the vertebrae from which they extended .
