The Late Pleistocene to the beginning of the Holocene saw the extinction of the majority of the world's megafauna, typically defined as animal species having body masses of 45 kg or more, which result

…suggestions that Paramylodon may have engaged in burrowing. Like other ground sloths, Paramylodon became extinct around 14–12,000 years ago as part of the Late Pleistocene megafauna extinctions of most large mammals across the Americas. Paramylodon overlapped in time with Paleoindians, the earliest human inhabitants of the Americas, who may…
