Abbreviated name for the Danish Tragterbecker or German Trichterrandbecher culture, alternatively known in English as the Funnel Beaker Culture. It is the first Neolithic culture of northern Europe, found in southern Scandinavia, the Low Countries, northern Germany, and northern Poland, in the later 4th and early 3rd millennium BC. It is characterized by the use of a funnel-necked beaker with globular body. It is thought to represent the acculturation of local Mesolithic communities by contact with the Linear Pottery culture groups further south. Five regional groups have been determined: western group in the Netherlands, sometimes associated with hunebedden (megalithic burial monuments); southern group in Germany; southeastern group in Czechoslovakia; eastern group in Poland; and northern group in Denmark and Sweden. Settlement sites are not well known, but burials are abundant, especially Dysser in Scandinavia and in Kujavian Graves in Poland; passage graves were eventually used. Other artifacts include ground stone axes and battle-axes, and copper tools appear in later phases. The TRB culture is succeeded by - and perhaps developed directly into - the Single Grave culture.
