Megatherium

Aside from its large size,‭ ‬Megatherium’s skeleton is extremely robust in its construction,‭ ‬and seems to be built not just to support its large body but to provide the maximum amount of stability.‭ ‬The lower bones of the short hind legs are comparable to the femur in thickness and development.‭ ‬Combined with a short but thick tail and a broad pelvis,‭ ‬the lower body effective becomes a seat for which the upper body can rest on.‭ ‬The price of this lower body development is that Megatherium certainly would not have broken any records for speed,‭ ‬and may have been one of the slowest animals in its ecosystem.‭ ‬However this would not be a problem as Megatherium probably would not have had to run to or from anything.
