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

Australovenator (name meaning "Southern Hunter"), also known as the Polar Allosaur, was a small to medium sized predatory allosaurid dinosaur that originated during the Middle Cretaceous period in Australia and Antarctica. Roughy 7 meters long and weighing a ton, it was a smaller, Cretaceous relative of the Jurassic Allosaurus that lived 50 million years earlier.


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. Aurtralovenator was green with yellow stripes and splodges.

Australovenator was a small theropods that had large heads lined with sharp teeth. Above the 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 future descendants of the great carnivorous Allosaurus of the Late Jurassic Period, about some fifty millions years earlier. Allosaurs were rare in the Cretaceous, but Australovenator survived at the South Pole. A fully grown Australovenator needed about 100 kilos of meat a week.

Behavior & TraitsEdit

Australovenator was a social hunter as is was 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 of these small kind came in contact over a circumstance such as food or already established territory, they would not tolerate each other's presence.
