re: In the North Dakota badlands. Is this anything?

And Wyoming

I saw a movie called "Badlands". It was pretty good.

Did you know that somewhere in the black mining hills of Dakota there lived a young boy named Rocky Racoon?

Thanks, Paul.

Looks like something to me. I am a geologist and took two semesters of invertebrate paleontology. Your choices are sedimentary structures like water ripple marks or the part of some shell. A third option is this is the cast of a rock that formed around a fossil. You then would be seeing the impression of a fossil. It's the part you are holding that makes it unclear. It looks like nothing. I'd need to see it from several angles to settle on a decision. But it isn't just a random shape.


I'd ask if the rock is cretaceous in age? There were all sorts of large oysters and clams and cephalopods at that time some 100 million years ago.

That's my two cents.

I’m currently working in North Dakota and went to Roosevelt National park a few times earlier this year. It is indeed part of the badlands.

Not sure what it is you found? What part of the park was it in?

This. Although I saw all those animals throughout the day. And Medora is a great place to visit. The Theodore Roosevelt library is being built there. They are building it in to the mountain from what I understand

Been there. Stayed at the hotel which is pretty cool. Was pheasant hunting south of there but got to travel a bit in the park. North Dakota is an under appreciated magnificent state both in the plains and in the western hills.

Prehistoric toilet paper.

Fossilized sand ripples from Noah's flood.

That's a chubby hand.
