Spinosaurs were not obligate piscivores

Calculations of bite force in Suchomimus [39] suggest that the bite may have been comparable to an alligator with a mandibular length of 50 cm suggesting that spinosaurs were capable of capturing terrestrial prey

Relative to the crocodilians, the spinosaurs generally both have higher absolute resistances to bending and torsion.

For a taxon such as Spinosaurus, the ability to feed on larger, struggling prey was not conferred by the possession of a snout that was relatively well equipped to deal with associated feeding loads, but may have been achieved by simple size-related advantages.
