Archaeological investigations conducted at Xalasco, Tlaxcala allowed discovering a great amount of ceramic, basalt and obsidian artifacts, as well as 2 human burials representative of the Classic period of Teotihuacan, material that confirms the presence and influence of this culture in eastern Tlaxcala.

The balance of research conducted by the National Institute of Anthropology and History (INAH) since 2005 was presented by archaeologist Alejandro Bautista Valdespino at the 5th Permanent Conference of Archaeology taking place at Templo Mayor Museum where he mentioned that studies have allowed defining the presence of 2 cultures at Xalasco site: a local one denominated Tenayac, and other clearly Teotihuacana.

The researcher informed that the material located is integrated by diverse ceramic elements, such as complete pots and figurines, as well as obsidian, flint and basalt artifacts representative of the Classic period.

Two human entombments were found, one of them a pot burial and the other associated with an offering and ceramics, as well as a series of animal rests such as falcons, dogs, fish and turtles, currently studied by archaeozoologist Fabiola Guzman from INAH Sub Direction of Laboratories.

Other important vestiges identified are stone representations of jaguars’ processions, same as those appearing at Teotihuacan murals.

“We think Xalasco was a Teotihuacan enclave that served as stopping point for commercial routes between the Gulf Coast and Central High Plateau during the Classic period. Eastern Tlaxcala region was part of one of the most direct routes that communicated the coast and the ancient metropolis of Teotihuacan”, mentioned the archaeologist at the forum organized by INAH Direction of Archaeological Studies.

The located theater-type censers, “common and characteristic of Teotihuacan, indicate adoption at Xalasco of rites, iconography and symbolism of the metropolis”.

Bautista Valdespino explained that the first work conducted by INAH at the site was a recognition tour conducted in 2005, which resulted in the recovery of archaeological material. In 2006, probing wells were excavated, and in 2008 exploration was carried on in a multidisciplinary and extensive way based on the project “Archaeological Salvage in a Conjunct with Teotihuacan Material at Xalasco, Atlzayanca, Tlaxcala”.

The project was co directed by INAH and the National Autonomous University of Mexico (UNAM) Institute of Anthropological Investigations, with the participation of archaeologist Linda Manzanilla and specialists of INAH Archaeozoology Laboratory.

At the first point explored in 2008 an exterior wall part of a structure was found. It is integrated with perfectly aligned basalt slabs, volcanic rock block filling and cornices carved in a local material named Xalnene.

The second exploration point allowed finding a room painted in red, with 1.1 meters depth and a probable funerary function.

Architectonic orientation is similar to Teotihuacan’s, which “confirms that Xalasco was inhabited by people from Teotihuacan society or related to it”.

“Characteristics of material found show a constant and dynamic interaction between different areas of eastern High Plateau; we may think this and other sites in Tlaxcala Valley had an important role in the development of Teotihuacan, allowing products transportation from the Gulf and what today is Puebla and southeast Estado de Mexico”.

Archaeologist Bautista informed that during 2009 off-site studies have been conducted, and analyses on lithic and ceramic material have already shown results. Carbon 14 dating is advanced, being the animal species located in the archaeological context identified.
