Hi all, I'm visiting friends on the TN River in TN and found an interesting (to me) rock. It has some characteristics that had me thinking fossilized bone, perhaps a scapula. There is a known archaeological site that goes back into prehistory until the civil war era that is nearby but I'm not saying that I think it's an artifact... although my imagination can take me to some fun places. I have no concrete ideas, it just struck me as odd, even for a river rock. Any input from those who know more than me would be awesome - thanks in advance!

Hi all, I'm brand new to rockhounding, and found this on the trip that started my interest this summer. I picked this up on a beach in the southern shores of Lake Michigan on the Michigan side. If I had to guess, I'd say it's sandstone with native copper inside. I don't trust my ID, however, because as I said I'm brand new to this hobby, and most of the state's copper is found in the northern regions. Can anyone here tell me if this is native copper? If so, I've seen some beautiful natural copper structures. I would love to get one out of the rock. Would muriatic acid dissolve the rock and leave me with the copper in its natural state? Thanks for any help you can provide!

Found these "rocks" in the backyard where we ran out new water line. Excavator was digging and saw an undug area with a smooth stone. Thought "oh cool, look how smooth". Turned out it had some ridges and wife said it might be a fossil, possibly a mollusk? Well my son finds the bigger one and also with ridges but in a weird pattern... There are a few fragments around that are black and tan in the backyard area with most just rigged/jagged. But they are similar looking color wise as these rounded ones. Hopefully we will find more... But what the heck are they?!

Any thoughts on what these could be? And if a case of the dreaded JAR, what kind of jar, please? thanks!
