Egyptian archaeologist Zahi Hawass examines the mummy KV21B in a storage room at the Egyptian Museum in Cairo before performing DNA sampling and a CT scan to determine its family tree.This mummy was discovered with another, KV21A, in a tomb discovered in 1817 in the Valley of the Kings. Both mummies may be queens from the 18th dynasty. Hawass and other Egyptian archaeologists consider KV21B a candidate for the body of Nefertiti.
