Egyptian chronology
Dendrochronology uses patterns found in tree growth rings to work out a date. That is possible for Egyptian chronology. An example is the Uluburun shipwreck, which is from the New Kingdom. By using both dendrochronology and radiocarbon dating, tree rings can be dated as far back as the Middle Kingdom. That was used for the coffin of Ipi-ha-ishutef (dated 2073±9 BC) and the funerary boat of Senusret III (dated 1887±11 BC; the conventional reign date is 1878 BC–1839 BC).
