were found at Cihuatán, in both residential and ceremonial contexts. These included obsidian cores, prismatic blades, and tools. Bifacial projectile points were also recovered, but were uncommon. These stone artefacts were typical of the Early Postclassic period. Site description Cihuatán was a very large Mesoamerican city. The city possessed two principal ceremonial centres, known respectively as the Eastern and Western Ceremonial Centres. In 1978 the Western Ceremonial Centre was cleared of vegetation and mapped. Excavations included a cluster of residential buildings that had been hastily abandoned due to fire, resulting in many of the household goods being preserved when the walls collapsed. The ceremonial architecture of the site core is of a pan-Mesoamerican style; outside of the ceremonial groups, the style is distinctively Maya. The Western Ceremonial Centre includes a large pyramid, a number of west-facing platforms that originally supported superstructures, and two -shaped Mesoamerican ballcourts. The excavator judged that the architectural styles of the Western Ceremonial Centre demonstrated the influence of Veracruz architectural styles. Radiocarbon dating suggests that the Western Ceremonial Centre was first built during the 8th or early-9th century AD. The Eastern Ceremonial Centre is contemporary with the Western Ceremonial Centre, but is architecturally distinct in both plan and style. NW 1/NW 3 was a residential cluster situated upon a long terrace. It consisted of two houses and two smaller structures, and their courtyards. The smaller structures may have been used to store maize. This group of buildings was abandoned due to fire, and many household objects were recovered in situ, including large food storage jars, cooking pots, and decorated ceramics. Evidence for the manufacture of obsidian tools was excavated, and for the spinning of cotton. P16 was a large structure situated on the West Terrace, in the centre of what was likely to have been the main marketplace in the city. Its construction style was similar to that of residential buildings, but it is likely to have served a specialist purpose. It had been burned, and contained ordinary domestic refuse. The south end of the building consisted of a very large workshop dedicated to the manufacture of obsidian woodworking tools. P22 was a small ceremonial platform located to the northwest of the Western Ceremonial Centre. It is badly preserved but was rectangular in form, with its entrance stairway on the west side.
