It contains cave art, most notably a total of 71 hand stencils, enumerated in the 1990s using ultraviolet photography,[1] but also linear designs and some animal paintings. In a 2018 study based on uranium-thorium dating, a hand stencil from the Cave of Maltravieso was dated to 64,000 years ago. This would make it Middle Paleolithic art, predating the presence of European early modern humans, with important implications for Neanderthal behavior.[2]
