Recent publications of excavations at Khirbet Kerak (e.g. Greenberg et al. 2006) and other sites of the Jordan Valley and Transjordan (such as Beth Shean, Tell esh-Shuna and Khirbet ez-Zeraqon) made available more data on the specialized ceramic production known as Khirbet Kerak Ware (KKW), providing a detailed picture of the typological inventory of shapes and a more accurate stratigraphic setting for its attestations. Ceramic material found at Tell es-Sultan, recently re-examined (Sala 2008b), has stated the existence of a series of local imitations of proper KKW (i.e. that produced at Khirbet Kerak and in northern Palestine). On the other hand, the examination of finds from southern Palestinian sites (et-Tell, Khirbet Yarmouk and Tell ed-Duweir) highlighted a slightly later diffusion of such a production (which in local imitations lasts until early EB IIIB) with a limited variety of shapes (mainly carinated or sinuous-sided bowls). Nonetheless, the diffusion of original KKW is associated in the main urban centres of the Southern Levant with a transformation of the city layout, defences and public architecture (emergence of palaces and the affirmation of a new type of in antis temples), usually marking the passage to EB III (revue)
