The order Pilosa
Origins and taxonomy
The
Mesozoic Era). The presence of these animals in Central America and their former presence in North America is a result of the Great American Interchange. A number of sloths were also formerly present on the Antilles, which they reached from South America by some combination of rafting or floating
with the prevailing currents.
Together with the
polyphyletic
; it contained unrelated families and was thus invalid.
