The megafauna of the Americas die out

about 13,000 years ago

Between about 14,000 and 10,000 years ago, North and South America lost about 35 genera of large mammals, among them mammoths, mastodons, giant ground sloths, glyptodonts, giant short-faced bears, sabre-toothed cats, horses and camels. Similar losses took place in Australia some 45,000 years ago and in Europe and northern Asia. The cause is much debated. Some scientists blame the arrival of skilled hunters, the Clovis people and their predecessors, while others point to rapid climate change at the end of the last ice age, or a combination of both. The loss changed ecosystems, since large herbivores shaped forests and grassland.
