See these the other day.
Remarkable find.
It is a early generation of dynasty that were guardians of the sacred ship, for those of you who are not aware, was buried next to the great pyramid. And is now a museum itself.
The wiki page will give you a few extra detail but there is much more to know.

I have has some long standing theories about that ship and many of them will be revealed in this find. Then you will know exactly where the first dynasties came from... who by the way, did not build those pyramids nor the sphinx.
They came to inhabit them and make them their own.
