The simple dolmen (German: Urdolmen, literally "ancient dolmen") or primeval dolmen[1] is an early form of dolmen or megalithic tomb that occurs especially in Northern Europe. The term was defined by archaeologist, Ernst Sprockhoff, and utilised by Ewald Schuldt in publicising his excavation of 106 megalithic sites in the north German state of Mecklenburg-Vorpommern. The simple dolmen emerged in the early days of the development of megalithic monuments of the Funnelbeaker culture (TBK) and around 3,500 BC they appeared across almost the entire region covered by the stone cult structures of Nordic megalith architecture, but not in the Netherlands, in Lower Saxony west of the River Weser nor east of the River Oder and only once in Sweden (Lejeby Laholm).
Neolithic monuments are an expression of the culture and ideology of neolithic communities. Their emergence and function serve as indicators of social development.[2]
