    Looks like a heavy creek stained patina on a piece of limestone. I found similar rock in a stream here and used another rock to chip a piece off to see a glowing white limestone under the crust. The white rock canvas gets a bright orange glow when there is a high iron/mineral content in the water that attaches to it over time making a cool patina.They are eye catching in the water also lol

        Could be a water worn brick.

          Could also be mud that has turned solid I find grey mud in one of my creeks that does it.
