Basic Giant Sloth Info
Giant sloths were a group
of large, ground-based sloths that evolved in South America and quickly radiated
through Central America and into Much of North America. Though some were
relatively small, others, such as the giant Eremotherium, were among the
largest land mammals of all time. They were very robust creatures and some had
an armament of massive claws backed by immense arm strength. More than 80 genra
have been recorded and a few of those are noted below.
Eremotherium
Eremotherium, also known as the
“Pan-American ground sloth”, was one of the largest (if not the largest) land
mammals ever recorded in the western hemisphere. With claws an amazing 23 inches
long, it stood up to 21 feet tall. It lived in the Americas starting in the late
Pliocene and ending with the Pleistocene mass
extinction.
Megalonyx
Megalonyx
is a well-known genus of giant sloth. It range over North America, as far North
as Alaska, starting in the late Miocene and ending with the Pleistocene
mass-extinction. The animal was originally discovered by cave miners in the
eastern USA, who sent claws and bones to amateur paleontologist, Thomas
Jefferson (yes, it’s the same Thomas Jefferson you think it is). The animal was
eventually named Megalonyx
jeffersonii.
Thalassocnus
Thalassocnus lived in Miocene and Pliocene South America. It was different
from most giant sloths in that it was semi-aquatic, like the hippopotamus of
today.
