Will someone please tell me what I have here?

Hi, I found these two stones in a creek bed in Northern Missouri. The only two I was able to come across thus far. I've honestly never seen anything like this, and was wondering if any of you folks had some insight? Thanks!!!

The bumps stick out on this, but they are smoothened bumps.

The bumps on the smaller rock though go inwards like small craters in the rock.

My first thought is metamorphic gabbro type rock, not fossil.

I'm guessing that both might be fossil corals,and that a Missouri Creek bed is unfortunately (at this moment,at least)insufficient information(problematic

provenance/stratigraphy).

Edit: I'll let the mistake stand,agreeing with Tony here

Augengneiss-type thingy?

Ok thanks for clearing that up. Wasn't sure if it was a fossil or not.

sorry I do not think it is a fossil

Definitely rocks , but good eye . The first in the left looks like a middle devonian fossil of placoderm fish armor . Again I must admit this looks geological vs being biological in nature .

They might not be fossils, but they're very cool rocks! If I were you, I'd keep those, maybe just in a garden or something.
