Archaeological inventories of chert and obsidian artifacts, Isla Cilvituk, Campeche, Mexico

With the permission of the Consejo de Arqueología, Instituto Nacional de Antropología e Historia, and under the authority of the Centro INAH Campeche intensive archaeological survey, instrument mapping, and test excavations were carried out at Isla Cilvituk, Campeche, Mexico, from 1994 to 1996. Isla Cilvituk is a large aggregated site, 50 hectares in size, located on an island in Laguna Silvituc and situated in a lacustrine zone that runs to the south from Lake Mocu, Campeche, to the Peten Lakes, Guatemala.
We completed a 100 percent full-coverage survey of the entire island and mapped an area of 60 hectares. Over 300 structures and features were recorded, and a systematic unaligned random sample of 280 test pits, 50x50 cm in size, was excavated. Four larger test excavations, 2x2m in size, were also placed in contexts that yielded stratigraphic and chronological information. All earth was screened through a 6mm mesh. Recovered material included ceramics, chert, obsidian, freshwater and ..., The chert and obsidian artifact assemblage from Isla Cilvituk, Campeche, was collected using the archaeological excavation methods described in the technical report for the project cited below (doi:10.48512/XCV8497393). Chert and obsidian artifacts were collected, washed, and cataloged in the field and curated at the Centro INAH Campeche. Digital photographs of selected chert and obsidian artifacts from the excavations are presented in a related Dryad database. Analysis and inventory of the chert and obsidian assemblage was completed at the Centro INAH Campeche by Richard Bureleson for his NMSU Master's thesis. With the permission of the Consejo de Arqueologia INAH, a sample of obsidian artifacts was sent to Missouri University Research Reactor (MURR) for sourcing via abbreviated NAA. Detailed results are summarized in a separate section of the technical report.  All obsidian artifacts analyzed at MURR were returned to the Centro INAH Campeche for curation and storage.
