Looking for opinions on this one! I’d say it’s a little greener In person than in the photos. It’s also slightly magnetic and dense for its size. Maybe a more seasoned rockhound or geologist may have some input!
Need a little bit of help, So came across this sort of oblong thick piece at a park in Southeast Pennsylvania. Was hesitant to pick it up wasn't sure if it was bone or something else can anyone identify it, especially most importantly if it's bone or not And if it is bone has it been modified...
