In this 2001 photograph, it is possible to see a number of interesting colors in the soil and residues around the baby’s burial in the central floor area of Building 3: red ochre and green pigment. When archaeologists find such anomalies in the generally beige-brown soil matrix at Çatalhöyük, they scoop it all up in its earth matrix to be examined under a microscope by conservators and soil and residue specialists in the labs of the compound. In this case, there was also some unburned wood to be examined that turned out to be fragments of what might have been a box. The piece of bone lodged in the mass of green turned out to be a bone spatula in what seemed to be a green paste, perhaps for coloring human skin.
