Olmec Jade Sculpture of a Standing Were-Jaguar

The Olmecs are generally considered to be the ultimate ancestor of all subsequent Mesoamerican civilisations. Thriving between about 1200 and 400 BC, their base was the tropical lowlands of south central Mexico, an area characterized by swamps punctuated by low hill ridges and volcanoes. Here the Olmecs practiced advanced farming techniques and constructed permanent settlements, including San Lorenzo Tenochtitlán, La Venta, Tres Zapotes, Laguna de los Cerros, and La Mojarra. However, the consolidation of their city--states led to notable cultural influence far beyond their heartland, and throughout the Mesoamerican region. This was confirmed in 2005 with the use of NAA (Neutron Activation Analysis) and petrography to demonstrate the spread of Olmec ceramic vessels.
