Higham et al.'s (2005) recent article in Radiocarbon 47(3) concerning diet-induced anomalies on radiocarbon ages for various faunal samples from Shag River Mouth is a well-considered study, building upon methodologies and research questions examining the phenomena of dietary anomalies addressed by Beavan Athfield and coauthors (cf. Beavan-Athfield et al. 1999, 2001a; Beavan-Athfield and Sparks 2001a,b,c). However, exception must be taken with one comment appearing in Higham et al. (2005) that suggests to the reader that there is a problem with the laboratory practice associated with rat bone dates measured at the Rafter Radiocarbon Laboratory of GNS Science, New Zealand.
