Imprints on the bones of a 21,000-year-old giant armadillo-like animal discovered in Argentina may be the oldest known evidence of humans in southern South America.
If confirmed by further excavations and research, the discovery would push back the likely human occupation of the area to about 5,000 years ago, to the end of the last ice age.
