Bonehunter Posted April 4, 2020 Share Posted April 4, 2020 Again from my "museum". This one was found in Warren county outside St. Louis and as close as I could tell at the time, it appeared to be an imprint of a "tusk shell". Guess it could also be curved nautaloid? Haven't changed that opinion, but haven't advanced my knowledge as much as I should have either! Thanks for any thoughts!! Bone Link to comment Share on other sites More sharing options...
