How long ago did megafauna live?

Answer 1

Megafauna, which refers to large animals typically weighing over 100 pounds, thrived during the Pleistocene Epoch, roughly 2.6 million to about 11,700 years ago. This period saw the existence of iconic species like mammoths and saber-toothed cats. Many of these large animals went extinct at the end of the last Ice Age, coinciding with the rise of human populations and climate changes. Thus, megafauna largely lived in the late Pleistocene and early Holocene periods.
