Cantabrian cave art is familiar from photographs reproduced in textbooks, but these two-dimensional images do not capture the irregularities of the rock surfaces on which animals and other designs were painted or engraved. Here, the authors use stereoscopic photography to review the parietal art of La Pasiega cave. By documenting the uneven surfaces of the cave's walls alongside painted and engraved marks, they identify new animal figures and reinterpret others, previously thought to be partial representations, as complete. The results show the positioning of animal figures to make use of concave/convex surfaces and rock edges to define the outlines of animals, reinforcing the need to record and interpret cave art three-dimensionally.
