Mark Kmiecik Posted March 11 Share Posted March 11 Both look like quartzite to me. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
DPS Ammonite Posted March 11 Share Posted March 11 Top one is chalcedony. Bottom one is iron-stained quartz related rock. 1 My goal is to leave no stone or fossil unturned.
