Micro sample 469


Maize starch recovered from residues on a sherd from a Rock Lake Net/Fabric Impressed Ware vessel (sample QE2006-D07) in Avonlea Phase deposits (see Meyer and Walde 2009 for discussion of Avonlea Phase ceramics). The sherd was found in a pit containing butchered bison bones that were covered with ochre, and the bones themselves date to approximately 1200 cal BP (Zarrillo 2008). However, organic residues containing the starch grains were directly AMS-dated giving a median date of 947 and range of 1055-800 cal BP. (Zarrillo 2008 and pers. comm. 2010).
