The one pic looks like a hoof print or lobe part of an ear as the other pic looks like a small head of a hoofed animal or something.
What a big piece. I would think not being a fossil. Its an indention.
Ya when I grabbed it the indentation was almost perfect side to side and front to back kinda like a hoof, not sure what would make it but something did, if your able to zoom in it looks like two points on front and the two on back.where the hoof would come together. It’s also cupped inside like what ever put pressure on stone it filled the void in it’s hoof. I do agree that it’s most likely not a hoof but resembles on very well. Thank you for responding. If you want different pics let me know. Thanks
