Martin saw correlation in the extinction of megafauna with the arrival of humans, and proposed his theory of ‘Overkill’. The term ‘megafauna’ is still used to refer to our largest living animals today such as the elephant.

Australian megafauna comprises a number of large animal species in Australia, often defined as species with body mass estimates of greater than 45 kg (100 lb) or equal to or greater than 130% of the body mass of their closest living relatives, that lived during the Pleistocene epoch. These species became extinct during the Pleistocene (16,100±100 - 50,000 years before present), but exact dates for their extinction have only been discovered recently.. Australian megafauna is a word used to describe a number of animal species in Australia that are quite a bit bigger than their closest living relatives.
