The statues and the majority of the petroglyphs and pottery at Zapatera have been dated to between 800 and 1350 CE, and is ascribed to the Chorotega, an indigenous Mesoamerican culture. Finds from this period also include utensils and zoomorphic figurines in a similar style to examples from the mainland. Some of the petroglyphs and pottery may date back as far as 500 BCE, and others are contemporary with Spanish colonies.
