What’s This Rock and What’s This Fossil. I was actually getting really good at my mineral identifications, I would try guessing the mineral before opening the three to see if I got it right or not. The fossil one because sometimes you got to see some really cool stuff, other time hilariously, bad fossils made with mosasaur teeth. And the occasional flint arrow head or hand axe but we’re not in the scope of the subreddit but still cool anyway.
