Megafauna are large animals that roamed the Earth during the Pleistocene, 2.5 million to 11,700 years ago. In Australia, megafauna included the huge wombat-shaped Diprotodon and giant goanna Megalania. European megafauna included Woolly Rhinoceroses, Mammoths, Cave Lions and Cave Bears.
The term megafauna generally describes animals above a certain weight threshold, and it can be divided into four categories. The biggest of all are the megaherbivores (>1000kg), such as elephants or hippos, true ecological engineers capable of altering vegetation on a landscape scale.
