I know a guy who found all kinds of native fossils . He is doing 5-10 in the pen right now. guess you cant sell them on ebay
When in Utah there was a listing for a garage sale close to where we were that listed artifacts so wife went (she is a collector too) She was the only one there and she was buying mostly clay pottery , It was priced cheap. After a while some guy walked in and looked around and made an offer for the whole lot and instructed my wife to pay for what she had already picked out. We thought that was the last we would ever hear about it till we were watching 60 minutes and there was a story about 3 people in Utah that had robbed grave sites or ceremonial sites and it was a huge thing , They did lots of time. We don't know if the guy who bought it all was a cop or not but we assume it was.
The mention of heart shaped rocks, I found a small one too and gave it to my wife . I thought it was a nature at it's best and one in a kizillion but now wondering if it maybe is man made.

all the hours I spent in a tractor I was constantly looking at rocks , One day it finally paid off , there it was , Nice big and heavy hammer , I was happy as a lark and still look in that area for more but it's planted to hay now.
