State of the (t)art. Analytical approaches in the investigation of components and production traits of archaeological bread-like objects, applied to two finds from the Neolithic lakeshore settlement Parkhaus Opéra (Zürich, Switzerland)
Species: a) Barley (Hordeum vulgare), and b) Bread wheat (Triticum aestivum). Grain parts and tissue types: 1) glume, 2) Pericarp and seed layers (corresponding to Fig 5, numbers 1 to 6), 3) aleurone tissue, 4) endosperm. Applied diagnostic features: 3a) Double to triple layer of aleurone in Hordeum, in contrast to 3b) Typically single layers as in Triticum and all other Old World cereal crops (, modified).
