Spinosaurus is known to have eaten fish and small to medium terrestrial prey as well. [5] Evidence suggests that it was semiaquatic; how capable it was of swimming has been strongly contested. Spinosaurus's leg bones had osteosclerosis (high bone density), allowing for better buoyancy control.
Juvenile spinosaurid fossils are somewhat rare. However, an ungual phalanx measuring 21 mm (0.83 in) belonging to a very young Spinosaurus indicates that Spinosaurus, and probably by extent other spinosaurids, may have developed their semiaquatic adaptations at birth or at a very young age and maintained the adaptations throughout their lives ...
Suchomimus itself was more adapted to a life hunting in shallow water due to its hollow bones, while Baryonyx and Spinosaurus were capable of fully submerging underwater and diving after prey. Courtesy of denser bones, the latter two spinosaurids could hunt underwater for prey and occupy a more derived lifestyle than Suchomimus could.

The newest addition to the Field Museum on Chicago's lakefront will give visitors a glimpse of the largest predatory dinosaur yet discovered via a 46-foot (14.02 meter) cast of a Spinosaurus ...
It also lacked the forward or backward inclination of Spinosaurus ' s neural spines. Its front corner formed a 3-centimetre (1.2 in) narrow-process, pointing upwards. The spine of the thirteenth dorsal vertebra has been only partly preserved; its upper and lower ends had broken off from taphonomic causes. From its general shape, the describers ...
Iberospinus (meaning "Iberian spine") is an extinct genus of spinosaurid dinosaur from the Early Cretaceous Papo Seco Formation of Portugal.The genus contains a single species, I. natarioi, known from several assorted bones belonging to one individual.
However, Spinosaurus and Suchomimus experienced even greater values of stress meaning that they could only consume light, small prey instead of larger items, which the stronger skull of Carcharodontosaurus could bite while sustaining the stress.
