Speleologists exploring a previously uncharted cave system beneath the Nullarbor Plain have discovered an expansive gallery of Late Pleistocene rock art. The paintings, executed in vibrant reds, yellows, and blacks, depict a variety of extinct Australian megafauna, including the giant short-faced kangaroo and the marsupial lion. The level of anatomical detail in the drawings suggests a deep, observational relationship between early humans and these now-vanished species.
Analysis of the pigments using uranium-thorium dating confirms the art is at least 40,000 years old. This find is significant as it represents the first major instance of polychrome (multi-colored) art from this era found in southern Australia, suggesting that complex artistic traditions were more geographically widespread across the continent than previously established by northern finds.
