Revised Energy Conversion Factor for Inulin-Type Fructans and Implications for Resource Ranking in Optimal Foraging Theory
Current conversion factors for calculating the contribution of carbohydrates to food energy are reviewed in light of recent advances in food science. The undigested carbohydrate inulin, which is present in many economically important plants, resists digestion by alimentary enzymes in the upper gastrointestinal system of humans, and reaches the colon chemically intact where it undergoes partial or complete fermentation by endogenous bacterial flor…

Assigning Context to Artifacts in Burned-Rock Middens
Accumulations office-cracked rock and carbon-stained sediment in pits mark locations of past cooking and heating facilities around the world. While the specific functions of these features may vary, the use of stones as heating elements in earth ovens is common. After repeated use, debris in the form of fire-cracked stones, charcoal, ash, sediment, carbonized plant fragments, and other materials accumulates to form low mounds known in the U.S. So…
Test Excavations at the Culebra Creek Site, 41BX126, Bexar County, Texas
Archaeological test excavations were undertaken at 4IBX126 on Culebra Creek to offset the impact from a proposed Texas Department of Transportation (TxDOT) highway improvement project on Loop 1604 in northwest Bexar County. Archaeological investigations were conducted in three field seasons: the first two seasons were conducted by TxDOT archaeologists and the third was directed by personnel from the Center for Archaeological Research (CAR) of The…
Site Formation Processes and the Origin of Artifacts in Plow-Zone Proveniences
Archaeological sites located in agricultural settings are subject to a number of post-depositional processes which can alter their original systemic context. This article presents a case that artifacts may be introduced to agricultural fields as secondary deposits in sediment transported during agricultural activities. As the practice of transporting sediment from one location to another in agricultural settings appear to be widespread, caution s…
A Brief Comment on the Immunological Identification of Plant Residues on Prehistoric Stone Tools and Ceramics
Fire-cracked Rock Use and Reuse in the Hueco Bolson, Fort Bliss, Texas
The Center for Archaeological Research of The University of Texas at San Antonio conducted an analysis of 29,058 pieces of fire-cracked rock and burned caliche selected from a sample of hundreds of features tested as part of the Hueco Mountain Archaeological Project at Fort Bliss, Texas. Feature and non-feature material included in this analysis were collected from site FB 13237 located on the proximal fan, FB 12719 within the basin area, and FB …
Additional comments on blood residue analysis in archaeology
A complement to a paper early in this year's volume of ANTIQUITY reports experience with searching for blood-residue traces with the services of a commercial testing laboratory
