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.
