Radiocarbon dating of 32 stratigraphic samples aided by Bayesian analysis has allowed the author to produce a high precision chronology for the construction and development of a continental Neolithic long barrow for the first time. She shows when and how quickly people living on the shore of the Baltic adopted pit graves, megalithic chambers and long barrows. Better than that, she provides a date for the famous cart tracks beneath the final barrow to 3420–3385 cal BC. Although other parts of the package — ploughing and pottery — are late arrivals, her analysis of the global evidence shows that Flintbek remains among the earliest sightings of the wheel in northern Europe.
