I looked all over for a date and got everything from "early 1800s" to "late 1800s" but nothing exact, so I had to make an educated guess. The first cameras practical enough to take such a photo were developed around 1840 and the excavations began in 1867.
Hah.
Just in case, though, I'll clarify: what I'd heard was that, when the German army was in Egypt in WWII, some German soldiers used the nose for target practice and pulverized it. No aliens required.
Edit: I'm remembering the story wrong: the target practice thing is attributed to Napoleon's troops using the nose as target practice for cannon. It'd unsubstantiated in either case; it turns out no one alive really knows.
