In June 2012 a team led by Alistair W. G. Pike of the University of Bristol in England dated the cave painting, "The Panel of Hands," which shows the outline of hands on the walls of the Cueva de El Castillo (Cave of El Castillo) in Puenta Viesgo, Cantabria, Spain, at a minimum of 40,800 years old, making it the oldest dated cave painting, perhaps 4000 years older than paintings in Chauvet Cave in France, which were previously thought to be the oldest cave paintings. The outlines of hands were made by blowing paint onto the wall using hands as stencils.
