My first impression was, "geofacts" (formed by natural, non-human processes). But, on closer observation, there are flakes of forms that can only be detached by a swiftly-moving (probably hard [stone]) hammer.

Also, there is also what appears to be a polyhedral core -- the source of deliberately-manufactured multiple sharp-edged flakes. That does not happen by accident...

One piece may have been used as a hammerstone; I'd really like to handle and examine that one!

Unfortunately, there is at least one piece that definitely appears to be of recent manufacture -- and never even exposed to dirt... (AKA "fake")... :-(

Anyway, I expect I'd have an enjoyable afternoon analyzing them firsthand...
