abyssunder Posted September 5, 2016 Share Posted September 5, 2016 (edited) All of them looks chert, to me, seeing the weathered concoidal fractures. In picture 3 seems to be a brachiopod/bivalve shell imprint.

caldigger Posted September 5, 2016 Share Posted September 5, 2016 Looks as if you've already identified the first one. Perhaps an artifact for cleaning off an arrow shaft for aerodynamics. Second one ? Third is shell imprint. Last is fractured chert. Link to comment Share on other sites More sharing options...
