|— Allen, on Australovenator|
Australovenator, ("Southern Hunter") also known as the Polar Allosaur, was a small to medium sized predatory allosaur dinosaur from the Cretaceous. It was a smaller, Cretaceous relative of the Jurassic Allosaurus about 50 million years earlier.
Australovenator lived in Australia and Antarctica during the Middle Cretaceous period from over 106-91 million years ago. Polar Allosaurs were the top predators in their ecosystem, living alongside other prehistoric creatures such as Muttaburrasaurus, Leaellynasaura, and Koolasuchus.
Australovenator reached about 5-7 meters in length, stood 2 to almost 3 meters tall, a weighed 1-2 tonnes in weight. They were the largest and fiercest predatory dinosaurs of their time and region.
Australovenator were smaller future descendants of the great carnivorous Allosaurus of the Late Jurassic Period, about some fifty millions years earlier. Allosaur types were rare in the Cretaceous, but Australovenator survived at the South Pole.
A fully grown Australovenator needed about 100 kilos of meat a week.
Australovenator was a solitary hunter. If two of these small kind came in contact, they wouldn't tolerate each other's presence - especially if food was involved.
