CHAT Hey Geologists, What Is This

I still think it’s a old piece of road......
very cool actually, it’s a rock made from our timeframe...

Not much gold in Pennsylvania. Gold in coprolites must be extremely rare.

More like nonexistent. How much Au is in YOUR poop? Unless you're eating somebody's gold fillings, likely essentially zip.

Dinosaurs had gizzards. They swallowed rocks for digestion. Gold in the rocks is not out of the question, but in PA it would have been rare.

Well at least I got my first thought validated - igneous rock of some sort

Looks like it has a cheezit stuck in it.

"Cheez its of the Gods"! V

My friend that is a rock hound would call it a "leaverite"..leave er right where you found it

Looks like a pegmatite, but my geology 101 dates from 1963.

Well, I've been doing a lot of heavy digging the past several days - and the job is not getting any smaller! But this area has nothing but heavy silt and lots and lots and LOTS of rocks. Enjoying rocks as I do, I toss aside several to examine later. Pretty sure I've come across some red or black jade (still testing) but in looking it up I came across a photo of jade porphyry that looks similar to the OP; the igneous rock is replaced, atom by atom, by the jade. Pretty cool....and now back to the digging. It gets hard once you're shoulder deep!
