I found a pocket full of stones like that in Colorado. I was told they were a morph of Goethite or Hematite. I thought they were really odd as everything around them was dusty and they were clean and shiny. I initially thought they were dino poop or meteorite fragments since they were all in a very small area!

I believe the pattern is surface, look at the edges where it tumbled in the river, they are wearing off. . .that was one reason I was thinking it could be epidermal. It feels like a smooth jasper.

From the dark metallic look, I'm betting you have a water worn piece of botryoidal hematite. If you have a streak plate, or the back of a ceramic tile, try a streak test. I'll bet you get a dark red streak. If it's hematite, it will also be heavy for its size.
If as I'm guessing, it is hematite, it's going to be messy to cab. It will turn everything within 10 yards of the grinder red. It's pure hell to wash off.

Thanks, Don! I will give it a scratch on the back of a tile. It does feel heavy for it's size.
James, nice pictograph! I have photos I should post sometime of a couple caves I was shown by a rancher. It has lots of drawings. Only the rancher, a couple close friends and a nearby Museum's anthropologist know that it exists.

Red ochre is a big component of early man's coloring process in this area. I find lots of hematite in plowed/timbered camps. Certain it was collected. Powdered form was used in burials commonly. Plenty of stock around here. Never any pictographs though. Too bad.  |

Sorry bout that. I was hoping for your sake that I was wrong. How cool would it be to have a piece of fossil dino skin ?

I was tempted to jump in as not skin for the very reason illustrated by the fossilized snake skin. Even reptiles with miniscule scales will show patterns "rows" or arcs of scales (i.e. a regular pattern and not a random one like that one the OPs specimen. Notice on the snake skin that the scales are in intersecting rows (diagonally from lower left to upper right, and also the reverse (upper left to lower right). Ain't nature beautiful. Tom
