This report documents the attempts to conduct amino acid racemization analysis for age estimation on the intra-crystalline protein fraction of Bithynia tentaculata opercula as part of the Trent project. It is concluded that the samples from Tattershall Castle, Tattershall Kirkby Area 3 and three of the samples from Tattershall Kirkby Area 2 are of MIS 5e age. One sample from Tattershall Kirkby Area 2 appears to be older, clustering with MIS 7 sites. The samples from Norton Bottoms, Coronation Farm, and Field House Brough have higher levels of protein decomposition, consistent with a correlation with MIS 7.
