While wandering last week in the South Luangwa national park in Zambia, I picked up this small ?flint flake from the ground. It is very thin - perhaps 5mm at the thickest portion.

I'd be most grateful for your thoughts.

No one likes my rock enough to comment... :(

Awwww. Well, it certainly has a rocky look about it, and, unless that's one enormous pencil, it's not a very big rock.
(The rockers must be on their hols.)

Now Chris, it's OK. I'm here and will attempt to identify this specimen.
Looks like a tool flake from some jasper (flint / chert.) It wouldn't be as good a tool source as pure chert because of the iron in it but is would cut well enough for a kill and some butchering.

Hi Jim
thanks a million; so you think it's been worked? That was my opinion because of the dimension (thin) and the angles of the edges.

It's not a rock !...it's a petrified crisp. If you had sought further clues in the locale you may have wandered across some petrified guacamole....some people mistake it for Aventurine.

Shut up Neil. Just because you win awards doesn't mean you know what you are talking about crisps? Heck, they are POTATO CHIP! (the English!, hrumph)

You know, taking a closer look, I think Neil could be right. If so, that would mean potatoes originated in Africa rather than the Americas.
Chris, you didn't happen to notice any evidence of a petrified potato chip factory while you were there?
