Also unearthed in Complex A were three rectangular mosaics (also known as "Pavements") each roughly and each consisting of up to 485 blocks of serpentine. These blocks were arranged horizontally to form what has been variously interpreted as an ornate Olmec bar-and-four-dots motif, the Olmec Dragon, a very abstract jaguar mask, a cosmogram, or a symbolic map of La Venta and environs. Not intended for display, soon after completion these pavements were covered over with colored clay and then many feet of earth.
