About 4,000 engraved slate plaques resembling owls—with two engraved circles for eyes and a body outlined below and dating from the Copper Age between 5,500 and 4,750 years ago—have been found in tombs and pits across the Iberian Peninsula.

A new study suggests that these plaques may have been crafted by young people and have been used as dolls, toys, or amulets.
