These findings not only represent an interesting dietary choice (and make one wonder just what ancient armadillo must have tasted like), but they also bump back the time of known human occupation of South America by about 6,000 years.Pleistocene ButchersScientists analyzed cut marks on parts of the pelvis, tail, and body armor of a creature called glyptodont, also referred to as N ...read more
