the vicinity of some special buildings that may have had ritual functions. These statues are half-size human figures modeled in white plaster around a core of bundled twigs. The figures have painted clothes, hair, and in some cases, ornamental tattoos or body paint. The eyes are created using cowrie shells with a bitumen pupil and dioptase highlighting. In all, 32 of those plaster figures were found in two caches, 15 of them full figures, 15 busts, and 2 fragmentary heads. Three of the busts were two-headed. Burial practices Considerable evidence for mortuary practices during the PPNB period have been described in recent years. Post-mortem skull removal, commonly restricted to the cranium, but on occasion including the mandible, and apparently following preliminary primary interments of the complete corpse. Such treatment has commonly been interpreted as representing rituals connected with veneration of the dead or some form of "ancestor worship". There is evidence of class in the way the dead are treated. Some people are buried in the floors of their houses as they would be at other Neolithic sites. After the flesh had wasted away some of the skulls were disinterred and decorated. This was either a form of respect or so that they could impart their power to the house and the people in it. However, unlike other Neolithic sites, some people were thrown on trash heaps and their bodies remain intact. Scholars have estimated that a third of adult burials were found in trash pits with their heads intact. They may have seen the newcomers as a lower class. `Ain Ghazal people buried some of their dead beneath the floors of their houses, others outside in the surrounding terrain. Of those buried inside, often the head was later retrieved and the skull buried in a separate shallow pit beneath the house floor. Also, many human remains have been found in what appear to be garbage pits where domestic waste was disposed, indicating that not every deceased was ceremoniously put to rest. Why only a small, selected portion of the inhabitants were properly buried and the majority simply disposed of remains unresolved. Burials seem to have taken place approximately every 15–20 years, indicating a rate of one burial per generation, though gender and age were not constant in this practice.
