How many other fossil human prints do we know of? I can't remember ever hearing about any.

There are quite a few. Mary Leakey found some nice ones in Africa, and they are arguing about some now in Mexico.

Telling male from female would be difficult, and most likely would relate to size and stride length, etc. There are currently some pretty good forensic types who can do amazing things, so they may have some techniques I don't know about.
