DO NOT EDIT THIS WITHOUT MY PERMISSION.Spinosaurus Aegpyticus (JPIV:P9449) is used in Jurassic Park IV:Extinction (Pythor9449) as the main dinosaur anganoist. 


This describes the behavior of Spinosaurus.


The Spinosaurus would fish often wading by rivers looking into the water,waiting for fish.It would also swim to get fish.When it wanted to, Spinosaurus would hunt dinosaurs like Paralititan,Ouranosaurus,Aegpytosaurus,and Anchisaurus.It would camoflague itself at strike at the right time.


The Spinosaurus would saty at the nest,guarding their young.They would keep their skull and arms around the nest,protecting it from predators and scavengers.The parents would bring prey for the kids.When the chicks were old enough,they would go on hunting trips and kill injured prey.


These are the organisms Spinosaurus killed.

  • Parasaurolophus

Feeding and Killing style

The Spinosaurus would feed on it's prey quickly,to save it and to let it rest.It would use it's claws and teeth to bite the neck of the prey.


These are the animals Spinosaurus preyed upon.

  • Parasaurolophus
  • Triceratops
  • Paralititan
  • Ouranosaurus
  • Apatosaurus
  • Brachiosaurus


Spinosaurus was poorly known after it's skeleton got bombed in World War II.In Jurassic Park III, A Spinosaurus killed a sub-adult Tyrannosaurus Rex,which was simple movie magic,as the Rex's first bite would have killed it.It was transported to Isla Tyrannus in 2005.


  • It is the tallest and longest carnivourus dinosaur,Tyrannosaurus Rex is second,with it being heavier,15-16 tons(30,000-32,000lbs).
