For more than 4,000 years, Indigenous Americans painted rock art depicting their conception of the universe in what is now southwestern Texas and northern Mexico, a new study finds.Innovative dating techniques revealed that the rock art, known as the Pecos River style tradition, likely first appeared almost 6,000 years ago and persisted until about 1,400 to 1,000 years ago, spanning roughly 175 generations.Over this period, the style, found in a region known as the Lower Pecos Canyonlands, remained remarkably consistent in the imagery and the techniques used to create the paintings, which appear to follow a strict set of rules,…
