Many Concretions have lines in them that makes it look like they spin in place wearing grooves in the outer shell. You can see them on the lower portion of this Concretion. DJI mini2 drone. #education #concretions #Ohio #fossilhunting #educational #creekside #nature #fossils | Ohio History Hunter | Facebook
