Is this a tooth? A claw? Or something else?

Hey everyone. I found these in a creek while traveling around Ohio. The areas are known for fossils, but I can't tell if these are actually teeth or if they are just some kind of rock formation. Any insight would be much appreciated.

Welcome to TFF from Austria!

 

These are sweet rugosa corals, aka horn corals, of Paleozoic age. In the second pic, you can clearly see the so-called septa in many of them.

Rugosa (link to wikipedia)

 

Edit: Classification as rugosa corals (not scleractinia corals) is based on the state they were found in.

If you were in SW Ohio (Cincinnati area roughly) they are almost certainly Ordovician in age and either the genus Grewingkia or Streptelasma
