The anaerobic conditions in Neolithic wetland sites allow perfect preservation of organic materials and therefore make precise dating possible by the help of dendrochronology. Not only the time period of a whole settlement can be precisely dated, but also the construction history of every single house. Beside precise dating, some excavations in Switzerland incorporate larger parts of the original Neolithic settlements including 10-25 houses. In these settlement parts large amounts of animal bones are identified and precise MNI (minimal number of individual) could be compiled. All these ideal preconditions make it possible to undertake some evaluation about meat consumption and its importance in Neolithic lakeshore sites. These hypothetical considerations are compared with some individual diet information based on isotopic results on single human bones from Neolithic settlements from Zurich. Including taphonomic aspects, these evaluations and comparisons lead to new insights of diet composition in Neolithic lakeshore settlements.
