Pre-Pottery Neolithic B is a division of the Neolithic developed by Dame Kathleen Kenyon during her archaeological excavations at Jericho in Palestine.
It differs from the earlier Pre-Pottery Neolithic A in that people living during this period began to introduce domesticated animals to supplement their earlier agrarian diet. The period is dated to between 9600 and 8000 BP.
Work at the site of 'Ain Ghazal in Jordan has indicated a later Pre-Pottery Neolithic C period which lasted between 8200 and 7900 BP.
