Have you heard the whispers of a place where time stretches back millennia? This is Zona Arqueológica Tlapacoya. Here at the foot of the Tlapacoya volcano lies a significant archaeological site. It rests on what was once the shore of Lake Chalco.
Tlapacoya was a vital center for the Tlatilco culture. Imagine the bustling life here between 1500 and 300 BCE. Tlapacoya figurines are especially famous. These sophisticated earthenware figures represent the Preclassic Period.
Also Tlapacoya was a manufacturing hub. It produced distinctive Dragon Pots. These flat-bottomed cylindrical bowls feature white or buff surfaces. They are incised with Olmec-style drawings. These drawings often depict were-jaguars.
But the story of Tlapacoya goes back even further. Some researchers suggest human habitation here as early as 25000 years ago. This claim is based on controversial findings. If verified, these would be among the earliest dates for humans in the Americas. Such a discovery would challenge prevailing theories about the settlement of the New World.
Evidence for these earlier dates includes animal remains. Bones of black bear and deer species were found. These remains appeared in middens associated with ancient hearths. A curved obsidian blade was also discovered. It lay beneath a buried tree trunk. The bones dated back approximately 24000 years. The obsidian blade dated between 21250 and 25000 years ago.
The discovery of Tlapacoya itself is quite interesting. It happened during the construction of the Mexico City-Puebla freeway. Sadly, the freeway construction almost obliterated the site.
Beatriz Barba played a crucial role in studying Tlapacoya. In 1955, she became the first Mexican woman to earn the title of archaeologist. Her master’s thesis focused on Tlapacoya. She evaluated the social development and religious practices of the Tlatilco culture. Barba’s work provided insight into the socio-economic and political life of Tlapacoya’s inhabitants. She also examined their trade relationships.
Human remains discovered at Tlapacoya offer more clues. Silvia González and her team claim that a Tlapacoya skull is the first directly dated human in Mexico. It dates back roughly 9730 years.
The name Tlapacoya comes from Nahuatl. It means “place where it is washed”.
The archaeological site is located in Santa María Tlapacoya. It’s part of the municipality of Ixtapaluca. The pyramid built on the side of Cerro del Elefante is a highlight. Traces of the Valley of Mexico’s first inhabitants have been found here. These remains date back to 7000 BC. Agricultural groups settled on the north side of the hill during the Formative period. Tlapacoya reached its peak between 400 BC and 200 AD.
After 100 BC, many people migrated to Teotihuacan. But Tlapacoya was not completely abandoned. Ceramic burial offerings from the Classic period have been found. The pyramid features a series of platforms. Evidence suggests three building stages. Stairways are located on three sides. Three tombs contained rich offerings. These included ceramic vessels, figurines, and adornments. Objects made from obsidian, serpentine, and jade were also found. These denote social differentiation.
Tlapacoya offers a glimpse into the distant past. Its artifacts and structures tell a story of ancient cultures. It speaks of early human settlements. It whispers of trade and social structures. As we leave this ancient site ponder the layers of history beneath our feet. Tlapacoya continues to reveal its secrets.
