   I think it is a Paramylodon harlani. And although it is at times difficult to see ground sloths as good for something, check the prominent muscle insertion marks all over the limbs of this one!

   The signage at the museum definitely says Megalonyx jeffersoni.

   If you are still there, please tell the staff members this is Paramylodon. Here is a photo of a full skeleton: http://www.biodiversitylibrary.org/item/138852#page/567/mode/1up
   On the contrary. here is a figure on the more gracile bones of the forearm in Megalonyx jeffersoni:

   Augusto,

   You make an interesting case. We’re not still there, but I was going to email our host at the museum anyway just to thank her for helping to make our visit so productive; so I will mention this when I do.
