What are these ???

[flip flop]

First off - I am a contractor, NOT a fossil guy.

I'm building a new home in Southwest Ohio. During excavation I noticed tons of small fossils. Sea shells, fish looking things, almost like there was an ancient ocean there. I noticed these 2 objects and picked them up. They look like maybe dolphin or orca teeth??

Any help would be appreciated.

Thanks, Flip Flop

I am not sure of the exact species but, they are commonly called horn corals.

Thanks for the picture re-size Kentucky.

Coral hu?? I guess my first clue to them not being teeth should have been the lack of roots.

Chuck and Worthy, thanks for the education.

Flip Flop, no biggie. Actually I hear of people finding "teeth" quite often and horn corals are usually what they have actually found.

Here is a solitary (single coralite or living chamber), rugose (concentric wrinkling on the exterior) coral which I have in my drawer. In other words, here's my horn coral:

We trenched for electric and geothermal earlier this week and tons of these came to the surface.
Harry, bring your wheel barrow and you can pick up all your collection can handle.

The thing to do is to pick out the most complete one or two specimens for your collection. Watch for any that may have another creature attached (a commensal or an opportunist that used the horn coral for a substrate). Also watch for the aberrant example which may be a different species.
