The most prominent finds from Zapatera were statues. According to records, they were carved of black basalt, generally between high, and more than in diameter. They depicted both humans and animals and are speculated to represent either deities or high-status individuals. Most are found around earthen or stone mounds, facing outwards, suggesting they formed part of a ceremonial installation. On the basis of engravings near these sites it has been proposed that they may have been host to human sacrifices.
