While G. phoenesis was thought to have been a relatively small species of giant sloth, some ancient sloth species were so big that their fossilized burrows are now caves in southern Brazil that humans can walk through.
One of the three pendants made from giant sloth bone.
However, Pansani said the team dated other material — sediment, charcoal and other giant sloth bones — from the same layer as where the artifacts were recovered.
Many experts are skeptical that humans occupied the Americas any earlier than 16,000 years ago, the study noted.
For the new study, Pacheco said the team hadn’t considered the possibility of trying to extract genetic material from the sloth-bone pendants.
