Re: Re: unique and unidentified
We have tried to break it open and if it were a form of shale, you would think that it would break. It only scuffs if tried. The casing can be broken if hit hard enough but it would ruin the unquiness of the speciman. It was I believe found in the Colorado/Idaho/Wyoming area.
