InGen Carnivore Profile: Spinosaurus

Referred to as a superpredator by Billy Brennan, the Spinosaurs on Sorna are seen as being both semi-aquatic fish eaters and terrestrial hunters. They hunt for fish in the deeper waters of the wetlands, using their long, croc-like jaws to snag the closest fish that comes in range. Next to still preying on the sawfish Onchopristis like the real animal, Spinosaurus will also prey on other aquatic animals such as small mosasaurs.

When hunting land based prey, Spinosaurus utilizes a hunting style similar to crocodiles by lurking near the edge of rivers to ambush unsuspecting herbivores. In a croc-like fashion, it will lunge out of the water and grasp the prey in it's jaws. But in other cases, it will actively hunt on land like traditional theropods.

Given it's size, Spinosaurus can hunt a large variety of prey depending on it's availability. It most commonly hunts ornithopods, with frequent targets being Edmontosaurus, Corythosaurus, Parasaurolophus, Maiasaura, Hypacrosaurus, Gryposaurus, Lambeosaurus, Iguanodon, Tenontosaurus, Saurolophus, Ouranosaurus, Tsintaosaurus and sometimes Shantungosaurus. 

From time to time, Spinosaurus will also target other prey like ceratopsians, stegosaurs and therizinosaurs, all the while staying away from large sauropods.

Based on live observation, Spinosaurus can kill it's prey in different ways. When attacking from the water, it bites down on the back of the prey and slashes it with it's claws to severely wound it before releasing it to let it die from blood loss. When hunting by land, it will charge forth and knock the prey down, pinning it with it's foot before delivering a neck bite. However, according to a live recording of a hunt involving a male Spinosaurus attacking a Shantungosaurus, said theropod was shown killing the hadrosaurid by clamping it jaws and large arms onto it's neck and twisting it.
