There is really nothing new about flowers found in a tomb. Many, many years earlier, Neanderthal burials were found with flowers and the remains of flowers. I realize that the Egyptian ministry wants to claim that everything that ever happened, happened first in Egypt. But that is not the case.
I'll be more interested when there are coherent details (perhaps on the Archaeology Institute of America website), because the sequence may be clarified, or at least muddled in a comprehensible way. :')
