The indigenous fauna of the West Indies collapsed in the Late Quaternary, with the rate of extinction for terrestrial mammals approaching 79-84%, one of the highest in the world.
However, in stark contrast to the American continent, radiocarbon dating indicates that mammals survived the end of the Pleistocene with no apparent, or minimal losses despite localized sea level rise and climate change.
[3] The indigenous peoples of the Caribbean arrived in the middle Holocene[4] and introduced guinea pigs, agoutis, and Native American dogs.
For example, Caribbean sloths coexisted with humans for up to 400 years, even the largest species, which might indicate that they weren't commonly hunted.
The most recent extinctions happened after the late 19th century, following the introduction of the small Indian mongoose for rat control.
