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.
The rivalry between Othniel Charles Marsh (left) and Edward Drinker Cope (right) sparked the Bone Wars.. The Bone Wars, also known as the Great Dinosaur Rush, [1] was a period of intense and ruthlessly competitive fossil hunting and discovery during the Gilded Age of American history, marked by a heated rivalry between Edward Drinker Cope (of the Academy of Natural Sciences of Philadelphia ...
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 ...

Spinosaurus differs from Oxalaia by its significantly more widely spaced tooth sockets, the presence of a slight narrowing between its third and fourth sockets, and the sharper slope of its snout. Oxalaia is currently assigned to the subfamily Spinosaurinae due to the morphology of its upper jaw and the absence of fine serrations on its teeth ...
The authors also proposed Spinosaurus maroccanus as a junior synonym of Sigilmassasaurus, and rejected the proposal of a Spinosaurus aegyptiacus neotype. [4] A study by British paleontologist Thomas Arden and colleagues in 2018 concluded that Sigilmassasaurus was a valid genus and formed a tribe with Spinosaurus termed Spinosaurini.
