ZARAGOSA, Spain—It took them 10 years of work, but a team of archaeologists claim they’ve identified the earliest known map of a region in western Europe: a prehistoric, pocket-sized hunting map made 14,000 years ago.

The object is a polished chunk of sandstone found in a cave in the Navarre region in northern Spain.

Above recognizable depictions of animals are etched lines that the scientists believe represent nearby mountains and a river. The reaction among archaeologists is mixed, however. One calls the rock “a pretty spectacular find,” but others question the team’s interpretation. “Multiple lines positioned over animal figures are not unusual in slabs of this period. We haven't traditionally considered them to be maps,” says the head of the prehistory division at the British Museum.
