Assessing diet and seasonality in the Lower Pecos canyonlands: an evaluation of coprolite specimens as records of individual dietary decisions
Highlights
► Application of diet-breadth models to coprolite data from Hinds Cave. ► Coprolites represent temporally discrete sets of individual behavior. ► Diets were seasonally variable but included a limited suite of staple resources.

Optimal foraging theory and diet-breadth models
A number of scholars have addressed the limitations of applying human behavioral ecology, specifically optimal foraging theory, to archaeological data sets (Gremillion, 2002, Murray, 2002, Yesner, 1985). The primary limitation in applying optimal foraging theory to archaeological data is an aspect of the data itself. Direct testing of diet-breadth models requires data of individual behavioral decisions (Winterhalder and Smith, 2000). The archaeological record cannot generally meet this
Hinds Cave excavation
Hinds Cave is a large limestone solution cave in the west wall of Still Canyon, approximately one-half kilometer above the confluence with the Pecos River (Shafer and Bryant, 1977). This east-facing overhang is located very high on the canyon wall and is difficult to access. Hinds Cave is located in the sotol-lechuguilla zone of the Chihuahuan biotic province within close proximity of the ecotonal boundary between this province and the oak-cedar zone of the Balconian biotic province to the east
Materials and methods
This section provides an overview of the components recovered from the thirty coprolite specimens included in this study and the methods used to accurately identify them. The first section reviews the development of reference collections for several of the major constituents recovered in many of the specimens. The development of these reference collections was a necessary step in fully evaluating the dietary components recovered. The following section reports on the laboratory procedures used
Results
The categorized macrofossil data of the thirty specimens are presented in Table 6, Table 7, Table 8. These data include plant, animal, and inorganic components recovered from each specimen. Fiber is the dominant component in almost every specimen (Table 6). Epidermal tissues of all four of the staple resources discussed throughout this research were identified and range in importance from trace to dominant component of individual specimens (Table 6). Epidermal tissues from a grass and at least
Discussion
The data from the current study expands prior dietary reconstructions for the Lower Pecos canyonlands. This discussion focuses on seasonality and diet-breadth interpretations of the clusters generated in this study. Overall, the data generated and synthesized herein suggest that a diet-breadth model using caloric return as the currency does not fully explain the seasonal dependence on low-ranked resources such as nopales and onion bulbs. The coprolite data corroborate the strong dependence on
Conclusion
Evaluating coprolites as the direct record of individual dietary choices over a short temporal window provides an excellent framework to assess the diet-breadth, seasonality of deposition and menus observed in past human subsistence patterns. There are three major seasonal menus reflected in the coprolite data. The first menu consists of nopales, and was principally, although not exclusively, consumed in the late spring. This menu is primarily consumed when other resources were not readily

2020, Earth-Science ReviewsCitation Excerpt :Macrofossils typically have a higher taxonomic resolution, though are biased towards smaller bones, and less digestible materials. Macrofossils, therefore, can provide a direct link to diet and even foods consumed together in “meals” (Pearsall, 2015; Riley, 2012; Sutton et al., 2010:51). However, while most consumed foods leave macrofossils in coprolites, these remains are often not identifiable after breaking down in the digestive system (see Section 7.2).

2019, Journal of Archaeological Science: ReportsCitation Excerpt :Foraging ranges and group sizes were likely controlled by the availability of desert succulents, particularly members of Dasylirion, Yucca, and Agave, and the wood required to cook them (Dering, 1999). Inhabitants of the area relied on these plant resources extensively, not only for food, but also as raw material for baskets, mats, and sandals (Shafer and Bryant, 1975; Alexander, 1974; Andrews et al., 1980; Stock, 1983; Dering, 1999; Riley, 2012). Archaeology of the Lower Pecos has long-relied on both traditional examination of fiber, bone, and lithic artifacts as well as coprolite analysis in order to reconstruct the lifeways of the early inhabitants of this area.

2019, International Journal of PaleopathologyCitation Excerpt :The fiber is largely derived from desert succulents. The coprolite data, as summarized and analyzed by Riley (2012) clearly shows the universal importance of desert succulents in the diet. However, the SMM coprolite stands out as a unique sample that is not dominated by plant fiber from succulents.

Through microhistological studies and comparison with reference material, Riley (2012) determined part of the diet of human coprolites from Texas's Hinds Cave. He identified epidermis of Agave sp., Opuntia sp., Allium sp., Poaceae, some Opuntia sp. seeds and Allium sp. buds.
