Super Cool Fossil? or Pretty Cool Rock?

Recommended Posts

I found this in the bank of the Iowa River amongst a nice collection of brachiopods. I have been trying to visualize an ancient living creature at the center of this rock, but I suspect my great discovery is nothing more than some type of weird rock. Would really appreciate your expertise and opinions!

 

I have included photos of

  1. Left outside
  2. Right outside
  3. Middle
  4. Left middle
  5. Right middle
  6. Closeup
  7. Fossils from reference layer.

Welcome to the Forum. :) 

 

This looks like a chert nodule or concretion.

Thanks guys! I was obviously hoping it would turn out to be a fossilized egg, but a chert nodule  probably makes much more sense.

Guess I’ll polish it up and turn it into a pair of earrings.
