Annotated skull diagram of Spinosaurus. Spinosaurid skulls—similar in many respects to those of crocodilians—were long, low and narrow. [17] As in other theropods, various fenestrae (openings) in the skull aided in reducing its weight. In spinosaurs however, the antorbital fenestrae were greatly reduced, akin to those of crocodilians. [30]
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.

Based on skeletal material from related spinosaurids, the skull of Oxalaia would have been an estimated 1.35 metres (4.4 feet) long; [5] this is smaller than Spinosaurus 's skull, which was approximated at 1.75 m (5 ft 9 in) long by Italian palaeontologist Cristiano Dal Sasso and colleagues in 2005.

Typical markings include vertical lines from the lower lip that extend to beneath the chin. [2] According to tattoo anthropologist Lars Krutak, the width of the lines and the spacing between them were traditionally associated with each of the nine groups of Hän Gwich’in. Girls would be tattooed to identify their group.
Though no skull material has been discovered for Ostafrikasaurus, it is known that spinosaurid skulls resembled those of crocodiles; they were long, low, narrow and expanded at their front ends into a terminal rosette-like shape, with a robust secondary palate on the roof of the mouth that made them more resistant to stress and bending.
