Marine Bivalve Feeding Strategies and Radiocarbon Ages in Northeast Atlantic Coastal Waters
ABSTRACT Marine mollusk shells have been extensively used to provide radiocarbon ( 14 C)-based chronologies in paleoenvironmental and archaeological studies, however uncertainties in age measurements are introduced because secondary factors such as vital effects and diet may influence 14 C incorpora...

ABSTRACT Marine mollusk shells have been extensively used to provide radiocarbon ( 14 C)-based chronologies in paleoenvironmental and archaeological studies, however uncertainties in age measurements are introduced because secondary factors such as vital effects and diet may influence 14 C incorporation into these shells. Deep burrowing and deposit feeding mollusks, in particular, may incorporate “old” carbon resulting in apparently older ages than their contemporary environment. In this study, we present paired 14 C and stable isotope (δ 13 C and δ 18 O) measurements for nine species of known-age bivalves having different feeding strategies and collected in six localities around the NE Atlantic. We exclude potential “old” carbon contamination in these known-age mollusk shells, acquire a better understanding of local ecology and provide an improved context for the environmental interpretation of 14 C ages. Our results indicate that, in the NE Atlantic, marine mollusk-derived 14 C ages provide a reliable basis for environmental and archaeological investigation, independently of vital effects and differences in microhabitats, feeding strategies and sample location—all of which are apparent from stable isotopes. |
