Vertebrate Fossil in WI?

[newbiecollectorwi]

Please help me identify this fossil found yesterday on a hike Door County.  It was found among very common fossils like corals.

Welcome to The Fossil Forum!

 

I personally believe this to be either more fossilized coral (simply due to the organic-looking features and because you say it is common where you are) or a very weird concretion. 

I do agree that these things sticking out (especially in the 2nd pic) look a lot like teeth, but the fact that there are so many big crystals inside makes me highly doubt that idea. 

 

Better pictures (more focused on the object itself) would help to confirm a positive ID for this piece. 

 

Enjoy your stay here!

Looks like a straight shelled Cephalopod bit with calcite crystals.

Better pic?

Looks like a siphuncle of a nautiloid.

Al Dente is correct.  It is the siphuncle of a straight-shelled nautiloid, Huronia.  This type of nautiloid is almost always found as just the siphuncle, as the rest of the shell was relatively fragile.

Nice to see some stuff from Wisconsin.

It's easy to find fossils in Door County.  I am very inexperienced in finding fossils and we managed to find these items roadside and near parking lots at parks.  There are more fossils just laying by some parking lots than what you'd know what to do with.

Beautiful corals!! Particularly like the chain coral.

Thanks for the pictures.
