The "Colossal Heads" are massive stone sculptures created by the Olmec civilization, which thrived in ancient Mesoamerica around 1200 to 400 BCE. These heads, carved from basalt, can weigh several tons and stand up to 10 feet tall. They are believed to represent rulers or important figures, showcasing the Olmec's advanced artistic skills and social hierarchy. Discovered primarily in the Mexican states of Veracruz and Tabasco, the Colossal Heads feature distinct facial features, including flat noses and thick lips. Each head is unique, with some displaying headdresses, indicating their significance in Olmec culture and society.
