Megafauna

Megafauna are the large animals of any particular region or time. Generally a "large animal" is defined as one weighing over 100 pounds (45 kg), though the threshold may range from 10 pounds (5 kg) up to 1 ton (1 metric tonne). The term is also used as a shorthand way of referring to particular groups of large animals, most commonly ones that became extinct in geologically recent times.
