Neil Judd’s archaeological team studied pottery to figure out when the Chaco buildings were used. This is possible because
A he had hired a specialist who could tell the age of ceramics by reading the signature on the bottom.
B they knew that they could find the most recently used pots at the top of the trash heaps.
C the pottery contained isotopes that could be dated and traced back to a specific period of time.
D specific materials, shapes, textures and painting styles are indicative to certain places and periods of time.
