Possible fossil mud cracks from Oklahoma

Cool piece of art but what is it? My grandparents had this fossil/rock in their home all my life and I inherited it a few years back, I was always fascinated by this fossil/rock as a kid and still as a adult. I would love to share this information with my grandchildren.

    This is almost certainly an example of “fossil” mud cracks. Mud shrinks and cracks as it dries and is then preserved in much the same way as a fossil. While not a true fossil of a living creature, it is still a relic from the ancient world and an interesting natural art object as you noticed.

    I’m not an expert but have you considered looking up dinosaur skin fossils. The piece you have resembles the edmontesaurus skin from South Dakota. I have a picture if you need to compair. Good luck.

    I believe it looks like Edmontosaurus dinosaur skin. I saw a sample fossil piece. Yours is more uniform, but that doesn’t mean yours didn’t grow differently. Good luck.

    Yes this is a cool rock, but I am sorry to say all the responses are wrong. The rock in question is a septarian nodule, they are common, but cool. Look it up! I have a few myself
