Joe_Sk1 Posted October 19, 2021 Share Posted October 19, 2021 I was guessing some sort of accreation but when a friend dropped it I became confused. Any help greatly appreciated. Found on friends property in the foothills of Denver, CO. USA near the Fossil Trace GG (yes they actually have fossils imbedded in cliffs and other features on the golf course.) P.S. I ordered a centimeter graph pad and hopefully this will be last "improper" post Link to comment Share on other sites More sharing options...
Rockwood Posted October 19, 2021 Share Posted October 19, 2021 I'm afraid this is going to be found to be a concretion. It is a common mistake however. Layered concretion can appear to look like a nut or fruit. 3 Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 19, 2021 Share Posted October 19, 2021 This is indeed a concretion.

Mark Kmiecik Posted October 20, 2021 Share Posted October 20, 2021 Very interesting concretion. Some form around organic matter. It may reveal a fossil if split open, or maybe not. Concretions are plentiful, so it's worth a shot. Wear safety glasses. Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

Joe_Sk1 Posted October 20, 2021 Author Share Posted October 20, 2021 Thanks a lot. The smoothness of the interior really tripped me up on this one. Link to comment Share on other sites More sharing options...
Rockwood Posted October 20, 2021 Share Posted October 20, 2021 I'd be surprised if a layered concretion like this held a fossil, but it probably wouldn't hurt. Well flying debris can sting. Link to comment Share on other sites More sharing options...
