There are three radiocarbon dates of the Neolithic site of Ba'ja (Bienert, Gebel 1997; Gebel, Hermansen 1999, 2001, 2004; Gebel et al. 2006; Gebel, Kinzel 2007). They were taken from a small test trench at the beginning of the 1997 excavation. Two later dates, Bln 5035: 6990-6650 BC and Bln 5036: 6820-6650 BC, provide dates ante quem for the occupation of the site, as the samples come from later deposits. Bln 5123: 7130-7045 BC is from a late occupation phase; but the older layers of Ba'ja have not yet been radiocarbon dated. According to the material remains, Ba'ja should be dated between 7500BC and 6900 BC (pers. comm. Gebel 2009).
