N2 - This report documents the attempts to conduct amino acid racemization analysis for age estimation on the intra-crystalline protein fraction of Bithynia tentaculata opercula and Valvata piscinalis shells as part of the Swale–Ure project. It is concluded that Ripon South is the youngest of the sites, although Ripon North is similar in age. Newby Wiske is older than the Ripon sites. The Sharow samples yielded extremely old ratios, but tests on the closed system indicated that these samples have been compromised, therefore no age attribution has been made.
