Allosaurus

***Allosaurus*** ("different lizard") was the most common predator of the Late Jurassic period and the most dangerous. Like most meat-eating dinosaurs, its jaws were filled with serrated teeth shaped like blades. Computer studies suggest that Allosaurus attacked by using its upper jaw like a machete to hack at its victim, then it used its lower jaw to bite out a slice of meat, although recent studies have proven this unlikely. In terms of size, it was the third largest theropod of its era, only the likes of the megalosaurid Torvosaurus (10-11 meters or 33-36 feet with a 4-5 tons of weight behind it) or Saurophaganax (12-13 meters or 40-43 feet with 6 tons of weight behind it) exceeded it in size and weight. It averaged around 8.5 meters long (28 feet) and around 3 meters (10 feet) tall. However fragmentary remains suggest lengths of 11 to 12 meters (36-40 feet), though its weight would be less than the Torvosaurus, which was the heavy weight theropod of the Jurassic.

It might have been easy for an Allosaurus to kill a fairly defenseless dinosaur-like Camptosaurus, but Stegosaurus can certainly fight back against it, even the sauropods (giant long-necks) like Brachiosaurus, Apatosaurus, Diplodocus, and Dreadnoughtus, were so huge that they could easily crush even an adult Allosaurus with a blow from their tail, or a stomp from their legs. Thus it is thought that the Allosaurus hunted in large hunting gangs, similar to that of the Komodo dragon. While this means they hunted 'together', it was still every Allosaur for itself. Often times, an entire gang of these dinosaurs would be killed by their prey or by natural hazards, showing they had poor group planning.

It is known that Allosaurus led a dangerous life. The Allosaurus on display at the Smithsonian Institute has a smashed shoulder blade, many broken ribs, and a lower jaw so damaged that paleontologists didn't realize it was an Allosaurus jaw for over 100 years! But these were tough dinosaurs: Their bones show that they lived long enough for their wounds to heal.

## Description

*Allosaurus* is blue, with a yellow underbelly, a ring around it's eye, and blue tongue. The *Allosaurus* has a red sharp spike over each eye. Bump-like scutes run along a row on the back of the neck and along the back.

## History

### Jurassic Park

*Allosaurus* was among the species attempted to be recreated, but only had 12% of it's genome complete by 1996.

### Jurassic World

*Allosaurus* was later recreated for Jurassic World, but it is unknown whether it was on display, although it had been chosen to be on the park's holoscope. Nonetheless, it was released after the December Incident forced the park to close.

### Post Jurassic World

The *Allosaurus* have remained consistent throughout the three-year time span Isla Nublar was abandoned, but when Mount Sibo threatened to erupt, a team of rescuers came to rescue as many dinosaurs as possible. As Mt. Sibo was erupting, one male juvenile Allosaurus ran to a Gyrosphere that Claire Dearing and Franklin Webb were using to escape the eruption, as he roared at it, believing that they can make it out alive, before he was hit by a falling magma rock.

At least five juvenile Allosaurus made it out alive, with one juvenile being sold by Gunnar Eversol to it's buyer, but the remaining *Allosaurus* is later seen running free in a stampede with other dinosaurs to escape the Lockwood estate, while the juvenile that was last seen in a truck being shipped off to its buyer.

One female juvenile Allosaurus matured to an adult. She was encountered at Big Rock National Park.

Allosaurus was seen scuffling in a Nasutoceratops pair, before she could attack again, the male Nasutoceratops arrived to protect his mate and his child. Then, the male Nasutoceratops led his herd and escaped.

As the Allosaurus investigates the place, she hears cries from the baby, causing her to turn her attention on the humans. Before she could kill them, she was forced to flee the camp, when she was shot by bolts from a crossbow by Kadasha on her face. It’s unknown if it is still alive or if the Allosaurus population is breeding.

## Status

*Allosaurus* are endangered due to there being only Five known individuals confirmed alive. All the juveniles matured, but it’s unknown if they are breeding.
