Re; Footprint and tracks, there is a place down the San Pedro River road that has dinosaur tracks, quite possible.
We need a paleontologist in the club.
I have either a large piece of magnetite or a meteorite that I found on Willow Springs ranch, one of these years I need to haul it down to the gem and mineral show and find a space junk guru....
No clue on @Stepmurr 's footprints. A professional maybe?
I know the ones you are talking about splitshot. Those are 24 million year old "rhinoceros" foot prints. It is pretty cool.
