Australovenator, a Polar Allosaur. A summer visitor from warmer lands to the north. He is a one-ton, ambush predator.

Australovenator (name meaning "Southern Hunter"), more commonly referred to as the Polar Allosaurus, is a genus of megaraptorid theropod dinosaur that originated during the Middle Cretaceous period in what is now Australia and Antarctica. A medium-sized predatory allosaurid measuring roughly 7 meters long and weighing a ton, it was a smaller, Cretaceous relative of the Jurassic Allosaurus that lived 50 million years earlier.

A pair of Australovenator were encountered in the episode "Ice Forest Spirits" and brought back to the park from Antarctica of 106 million years ago. The pair, one individual named Hunter, now reside in a cold forest enclosure of the park with their four offspring.


Era & DiscoveryEdit

Australovenator lived in Australia and Antarctica during the Middle Cretaceous period from over 113 – 100 million years ago. They were the top predators in their ecosystem, living alongside other prehistoric creatures such as Muttaburrasaurus, Leaellynasaura, and Koolasuchus. It was first discovered and described in 2009 by paleontologist Scott Hocknull and colleagues of the Queensland Museum.

Physical AttributesEdit

Australovenator was small compared to its Jurassic ancestors, reaching about 16.5 – 23 feet (5 – 7.2 m) in length, standing 6 – 9 feet (2 – 3 m) tall, a weighing 1 – 2 tons (2,000 – 4,000 lbs.) in weight. They were the largest and fiercest predatory dinosaurs of their time and region. Ausrtralovenator was green with yellow stripes and splodges.

Australovenator was a small theropod with a large headlined with sharp teeth. Above its eyes was a flat, hard, relatively small, head crest. Like the other carnivores, they had large, thick legs as well as relatively large arms with three digits per hand.

Australovenator were smaller descendants of the great carnivorous Allosaurus of the Late Jurassic period, around fifty million years prior to Australovenator. During the Cretaceous, Allosaurs were rare dinosaurs, but the Australovenator survived at the South Pole. A fully grown Australovenator needed about 100 kilos of meat a week.

Capabilities and WeaponryEdit

  • Agility
  • Claws
  • Speed
  • Teeth

Behavior & TraitsEdit

Australovenator was both a social hunter as much as a solitary one, getting together with others of its kind during mating season but also hunting in packs to help bring down larger prey such as Muttaburrasaurus. They were able to hunt nearly anything - from the small Leaellynasaura to the large Muttaburrasaurus. With their sharp teeth which were mementos of a bygone golden age, they could slice through the toughest hide.

However, if two Australovenator came in contact over a circumstance such as food or already established territory, they would not tolerate each other's presence, even if it was between a male and a female.



  • The sound effects of Australovenator are similar to the Allosaurus, however, they are altered because of its smaller appearance. Additionally, it was given the sound effects of a polar bear, cougar, snow leopard, lynx, and walrus.
