Using stable isotope analyses to assess the geographical origins of pork and beef products in a historical New World population center (2016)
DOCUMENT Citation Only Eric Guiry. Michael Richards.

This presentation explores the utility of stable carbon and nitrogen isotope analyses as a method for tracing the geographical origins of meat products from major livestock species. Samples (n= 250) from pigs and cattle consumed in the historical city of York, later renamed Toronto, in Canada are compared with animals raised in other areas, in both local as well as distant regions. Results show how cultural as well as environmental isotopic variables can be used to distinguish between animals...


Variability in Carbon and Nitrogen Isotope Ratios in Banana Yucca (Yucca Baccata) from Cedar Mesa, Utah: Environmental, Inter-Organ and Processing-based Effects (2015)
DOCUMENT Citation Only Michael Lewis. RE Burrillo. Joan Brenner Coltrain.

Recent stable isotope and phytolith studies suggest that desert succulents (in particular Yucca sp. and Opuntia sp.) were a non-trivial component of Ancestral Puebloan diets. However, isotopic variability in such resources is poorly documented. We present 𝜹C13 and 𝜹N15 values for fruits and seeds of thirty modern Banana Yucca (Yucca baccata) specimens from Cedar Mesa, Utah. Experimental roasting and simulated mastication of yucca ‘crowns’ allow separate assays of whole tissue, fiber, and...


What did you have for dinner last night? Revealing diet, mobility, and movement of people within Middle Iron Age British society through multi-isotopic analysis (2016)
DOCUMENT Citation Only Derek Hamilton. Kerry Sayle. Colin Haselgrove. Gordon Cook.

The Middle Iron Age in southern central Britain (c. 300–150 cal BC) is a period that is often seen as becoming regionally inward-looking. A primary focus of the mixed agriculturalists is on building and maintaining massive hillforts. There is very little long-distance exchange or trade noted in the archaeological record, and the metalwork at the time takes on insular forms (e.g. involuted brooches) that separate it from the Continental connections observable in both the Early and Late Iron...
