Egyptian chronology
This is using archeaology to put events in order, or a sequence. It does not fix a person or event to a exact year. A series of events can provide evidence to provide or support a precise date. For example, a number of stone vessels of the rulers of the first two dynasties were placed in rooms under the Step Pyramid of Djoser. They were sealed off by during the building of the pyramid during the Third Dynasty. Another example is stone blocks from the Old Kingdom with the names of several kings. Thee stones were later used to build the Middle Kingdom pyramid-temples at Lisht. The third pylon at Karnak, built by Amenhotep III had "fill" material from the kiosk of Sesostris I, as well as stelae of the Second Intermediate Period and the Eighteenth Dynasty of the New Kingdom.
