One of the earliest known instances of wild carnivores being held in captivity in Meso­america dates to around the second century in Teotihuacán; excavations starting in the late 1990s uncovered the remains of almost two hundred animals—including wolves, eagles, and jaguars—in the Pyramids of the Sun and the Moon. The skeletons showed bone breaks, bone fusion, and abnormal growths, as well as indications of a human-controlled diet.
