With an attitude matching that of even Tyrannosaurus and Carcharodontosaurus, Megalosaurus is a nightmare brought to life. Many herbivores fear this predator for it's brutality, which is considered legendary by observers who watch it hunt. It's so aggressive that even a loud roar is enough to send shivers down a person's spine. While they are rare to spot on Isla Sorna, sightings are more frequent on Isla Matanceros 


On Sorna, Megalosaurus is seldom seen. Those who have been observed can be found living mostly in dense forests, but some have also been found in jungles and around plains, which is where they hunt. On Matanceros, female Megalosaurs with offspring seek shelter in caves while males live around the tropical forests, yet both of them hunt in the open badlands and grasslands. Mothers will often drag their kills into the caves to feed their offspring. Juveniles stay deep within the forests during the morning and come out at night to hunt, keeping out of range from the aggressive adults.


Megalosaurus is exclusively solitary and does not hunt or live in groups. They are extremely aggressive and highly territorial, refusing to allow any other predators to trespass. Males and females are especially aggressive with each other outside of mating season, with fights being very serious. Even juveniles can be dangerous as they come of age. However, females become incredibly violent as mothers, attacking anything that threatens their young, including rogue males. 

Megalosaurus, compared to most theropods, is also one of few predators, along with Velociraptor and Carnotaurus, who are known to be man-eaters. There have been reports of this dinosaur frequently attacking and devouring humans that venture onto the island. Poachers are the most frequent victims due to various hunting expeditions failing with them being eaten by Megalosaurs.


Megalosaurus are vicious predators who mainly prefer hunting large prey. Favored targets include Iguanodon, Corythosaurus, Parasaurolophus, Maiasaura, Lambeosaurus, Barsboldia, Edmontosaurus, Gryposaurus, Apatosaurus, Shunosaurus, Camarasaurus, Mamenchisaurus, Saltasaurus and Hypacrosaurus. They'll even take tough prey like Triceratops, Pachyrhinosaurus, Centrosaurus, Torosaurus, Stegosaurus, Wuerhosaurus, Styracosaurus, Arrhinoceratops and Pentaceratops.

Juvenile Megalosaurs settle on hunting down smaller prey like Thescelosaurus, Dryosaurus, Ornithomimus, Struthiomimus, Pachycephalosaurus, Montanoceratops, Avaceratops, Leptoceratops and even Scelidosaurus. 

On some rare occasions Megalosaurus will scout along beaches for dead marine animals that were washed ashore.

Megalosaurus kills it's prey through two different ways, such as weakening it with a quick bite to the legs to make it bleed or suffocating it by biting at the throat. 

Interspecific Competition

On Isla Sorna, Megalosaurus periodically finds itself in fierce competition with other carnivores such as Tyrannosaurus, Allosaurus, Carcharodontosaurus, Giganotosaurus, Carnotaurus, Torvosaurus, Albertosaurus, Fasolasuchus and Acrocanthosaurus among some others. Given it's ferocity and aggression, Megalosaurus shows no fear and will instantly fight any predator that provokes it. One such occurrence involved a female viciously defending it's kill from a marauding Torvosaurus.

Juveniles on the other hand commonly contend with smaller predators, most notably raptors.

On Isla Matanceros, Megalosaurus competes with Carcharodontosaurus, Gorgosaurus, Eocarcharia, Sinraptor, Achillobator and Neovenator. Out of them all, it's most common enemy is Gorgosaurus. Observers that study these animals have theorized that Megalosaurus and Gorgosaurus see each other as natural rivals, with said rivalry being compared to that of lions and spotted hyenas. Both predators have been seen hunting for the same prey on a regular basis, which causes their hunting grounds to overlap. Megalosaurs more frequently target young Gorgosaurus, killing them for the sole purpose of limiting the competition rather than for food. While Gorgosaurs rarely do the same in return, they are known for chasing young Megalosaurs off carcasses. Juveniles of both species will preferably avoid each other, but at least one sighting of two juveniles fighting over a hadrosaur carcass has been filed.

And here it is, the dinosaur known as Megalosaurus. This dinosaur rarely gets any respect in the media or even in paleontology.

I just had to do this one.

But anyway, tune in next time for the famous abelisaur known only as Carnotaurus, the "Meat Eating Bull".
