Hello everyone I am new here and will soon update my profile but was too interested in finding out the ID of this interesting looking formation. I am located in Lincoln County Missouri where this particular specimen was found I'm not quite sure what I'm looking at I have ideas but would like some expert input as I am new to this, this being a childhood fantasy of mine finding fossils paleontology archeology and geology lol. Any help or points in the right direction would be much appreciated thank you so much for allowing me to join this platform.
