Fossildude19 Posted March 15, 2023 Share Posted March 15, 2023 Looks more like a modern scleractinian coral skeleton. 2 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Once you've seen a few thousand it's easy to tell. If the specimen weighs much less than a rock of comparable size it's modern. If it tends to float and/or sinks VERY slowly when completely dry. Fossils are more of a "rock" color. 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...
