All I can figger, is probably some little injun kid dropped a Milkdud after trick-or-treating at the neighbors tipi and squished it with his little moccasin. It then layed there long enuff to petrify, before I picked it up....
Don...its an egg.
Don't know what kind, but google up some dinosaur eggs and you'll see the similarities. Yours might be a bird, snake, or lizard egg...but Im betting thats what it is.
Injun scat don't have clear centers...
