Fossil Friday

This week on Fossil Friday we have a pair of interestingly textured specimens.


What could they be? Animal, vegetable, or mineral? Okay, most certainly mineral at this point. But what were they originally? They date from the Devonian and were collected in a quarry in North Liberty, Iowa. First person to identify them wins bragging rights for the week!
