Neolithic

Are baking plates, typical for the middle and late Neolithic cultures of western Europe also known from the younger Neolithic (FR)?

Baking plates are known from the Cerny- und Chassey-cultures, the Bourgogne middle-Neolithic and the Michelsberg-culture, ca. 4500-3500 BC). Their use seem to stop abruptly around 3500 BC caused by another way of baking bread. Maybe from this time onward, people used to bake directly on hot ashes, hot stones, pots or the inner walls of furnaces...
