The African bush elephant, Earth's largest living land animal

The term megafauna [1] is mostly used of land animals. Some use it to mean over 44 kilograms (100 lb),[2][3] but for others it means over 100 kilograms (220 lb).[3][4] The term includes many species not usually thought of as large, such as white-tailed deer and the red kangaroo, and even humans.

The term is especially used for the Pleistocene megafauna – the large land animals of the last ice age, such as mammoths.[5] It is also used for the largest living wild land animals, especially elephants, giraffes, hippopotamuses, rhinoceroses, elk, condors, etc. Megafauna may be split into megaherbivores (e.g. elk), megacarnivores (e.g. lions), and more rarely, megaomnivores (e.g. bears).
