Abstract The Atacama Desert coast (18–30° S) presents one of the earliest chronologies in the South America region, whose first occupations date from ~ 13,000 cal BP. Since that time, coastal and marine resources have been a common component at sites along the littoral zone. Fish species have been particularly important, as have the fishing technologies developed and used by the coastal communities. However, even though several archaeological sites have been studied, there is no systematic macro-regional analysis of early fisheries along the Atacama Desert coast. Furthermore, differences in theoretical and methodological approaches, as well as research objectives, hinder comparisons between ichthyoarchaeological assemblages. Here, we present a comparative analysis of the Atacama Desert fish data obtained from publications and gray literature from ten archaeological sites dating from the Terminal Pleistocene to the Early Holocene. Through the standardization of contextual and ichthyoarchaeological information, we compared data using NISP, MNI, and weight to calculate fish density, richness, and ubiquity, in order to identify similarities and differences between assemblages. This exploratory approach aims to contribute to studies of fish consumption in the area, as well as proposing new methodological questions and solutions regarding data heterogeneity in archaeozoology.

Abstract The late Quaternary in North America was marked by highly variable climate and considerable biodiversity loss including a megafaunal extinction event at the terminal Pleistocene. Here, we focus on changes in body size and diet in Neotoma (woodrats) in response to these ecological perturbations using the fossil record from the Edwards Plateau (Texas) across the past 20,000 years. Body mass was estimated using measurements of fossil teeth and diet was quantified using stable isotope analysis of carbon and nitrogen from fossil bone collagen. Prior to ca. 7000 cal yr BP, maximum mass was positively correlated to precipitation and negatively correlated to temperature. Independently, mass was negatively correlated to community composition, becoming more similar to modern over time. Neotoma diet in the Pleistocene was primarily sourced from C3 plants, but became progressively more reliant on C4 (and potentially CAM) plants through the Holocene. Decreasing population mass and higher C4/CAM consumption was associated with a transition from a mesic to xeric landscape. Our results suggest that Neotoma responded to climatic variability during the terminal Pleistocene through changes in body size, while changes in resource availability during the Holocene likely led to shifts in the relative abundance of different Neotoma species in the community.
