added by archaeologs A large Iron Age settlement mound north of Wau in the Bahr el Ghazal Province, in the Southern Region of the Sudan. Throughout the occupation, which began around the middle of the 1st millennium ad, pottery was decorated by means of a twisted cord roulette. A similar technique of pottery decoration is practised today by several Nilotic-speaking societies. The most important change to be discerned in the Wun Rok sequence was the replacement, in around the 12th century, of the earlier humpless cattle by humped ones akin to those herded by the recent Nilotic-speaking population of the area. Würm. A group of Quaternary deposits in the Alps and the valleys of south German rivers. The Würm consists of moraine and related river terraces of proglacial deposits. It formed part of the classical scheme of four glacials with intervening interglacials, published in 1909 by Penck and Bruckner. In this scheme, it was held that the Würm deposits represented only one cold stage, the latest. More recently, it has been discovered that the Würm terraces are the result of more than one glacial advance. They also comprise deposits of several interglacials, including the Holocene. The Würm deposits therefore represent a much more complicated sequence than was at first supposed. For this reason, the term Würm should only be used to describe this particular group of Alpine deposits. Unfortunately, ‘Würm’ has gained wide currency as a more general term, meaning the latest cold stage (Weichselian, Devensian) throughout Europe; this is still common in archaeological literature, but should be avoided.
