This paper provides an isotope-ecology context for Cedar Mesa, Utah by presenting isotope data on over 400 modern botanical and archaeo-faunal specimens from the area. While carbon data fit with regional expectations, nitrogen isotope ratios throughout the Cedar Mesa food-web show depletion in 15N relative to other ecosystems in the intermountain west--consistent with nitrogen inputs from cyptobiotic soil crusts. In light of this localized isotope baseline, we reassess previously published...
