A project was initiated in 2007 to assemble and analyze the entire collection of invertebrate and vertebrate archaeofaunal specimens recovered from Las Vegas phase associations in southwestern Ecuador. Only small samples had been previously identified, while the bulk of recovered materials were housed in the collections of the Environmental Archaeology Program of the Florida Museum of Natural History (FLMNH) and at the field laboratory in Cautivo, Santa Elena Province, Ecuador. Vertebrate specimens were analyzed at the FLMNH, the Archaeological Analytical Research Facility (AARF) of Binghamton University, the American Museum of Natural History (AMNH)and the Musée National d’ Histoire Naturelle (MNHN). Invertebrate specimens were analyzed in Cautivo. The analyses (Stahl and Stothert 2020) add significant detail concerning early sedentary maritime foraging and horticulture from one of the best known Early Holocene archaeological cultures in the western hemisphere.
The Las Vegas culture is known from its type Site 80 and as many as 31 smaller campsites in the extreme western portion of the Santa Elena Peninsula, Ecuador. At Site 80, a pre-Vegas phase occupation may date to before 13,000 Calib BC, with ample evidence for as much as 5,000 years of subsequent occupation. The Las Vegas phase occupations reveal evidence for early horticulture, sedentary foraging, hunting, and fishing, and elaborate burial practices with almost 200 recovered individuals. Site 80 was first discovered in 1964, and major excavations were undertaken from 1977 to 1985 under the auspices of the Banco Central del Ecuador, with research continuing into subsequent decades. Most of the site now lies within the precinct of the Museo Los Amantes de Sumpa. Previously, small samples of associated archaeofaunal material were identified and recorded (Byrd 1976; Stothert 1988). In 2007, efforts were initiated to identify and record the entire sample of recovered invertebrate (identified MNI=21,886) and vertebrate (n=45,120) archaeofaunas. The assemblage presented here consists of 41,633 mammalian and unidentifiable archaeofaunal specimens recovered from seven archaeological sites. The entire faunal data base is detailed in Stahl and Stothert (2020).
Archaeofaunal specimens were recovered from seven Las Vegas archaeological sites in the Santa Elena Peninsula of Southwestern Ecuador. Analyzed assemblages in this study include specimens that had been curated since the 1970s in the collections of the Environmental Archaeology Program of the Florida Museum of Natural History (FLMNH), and specimens that were stored at the field laboratory in Cautivo, Santa Elena Province, Ecuador. The entire assemblage was sorted in Cautivo and at the Archaeological Analytical Research Facility (AARF) of Binghamton University. Invertebrate specimens were identified at Cautivo. Fish specimens, and herpetological and avian specimens, were sent in their original containers with recorded provenience information inside curation-grade boxes to the Musée National d’ Histoire Naturelle (MNHN) and Millsaps College, respectively. The mammalian specimens were identified through comparison with the collections at the AARF and additional identifications were undertaken in the Department of Mammalogy, American Museum of Natural History (AMNH). Upon completion of this study, all materials were repackaged in their original containers with recorded provenience information and returned in labeled curation-grade boxes for permanent storage to the FLMNH. Preserved specimens were recovered from each site; however, the bulk by number, weight, and volume are associated with Site 80. A total of 41,633 (13,711.52 g) mammalian and indeterminate specimens were tabulated in database files (Paradox), according to: Site, Provenience, Level, Quantity, Weight, Maximum Size, Identification to Class, Order, and Family with associated size (S,M,L), Genus, Element, Portion, Side, Differential Preservation in quartiles of Scan Sites where applicable, Dentition Present, Fusion/Eruption, Heat Modification, Surface Modification, Breakage, and Comments.
Potential Applications of the Data
The Las Vegas Culture is one of the most intensively studied assemblage of an early maritime-based sedentary human occupation in the western hemisphere, with a large burial component, and evidence for early horticulture. It can minimally be used as a standard comparative sample for early archaeological contexts found throughout the neotropics of Panama, Colombia, and Peru.
Analysis of all recovered archaeofaunal specimens was made possible through funding awarded to Peter Stahl from the National Science Foundation (BCS0739602).
