Fossils in limestone

There has to be 1000's of creatures preserved in this rock. I probably walked over it 100 times before I actually took a close look at it. I am at/close to the intersection of the Clarendon fault line and the Niagara escarpment.

Indiana invertebrate fossil

I thought it was a bullet at first glance, but now it looks like a mushroom fossil. Further looking tells me that mushrooms don't fossilize so have no clue what it is.

Bottom view of the Indiana fossil.

The area it was found is known for sea life, but I know it is not a shell due to the gills on the underside of the fossil, also it is not thick enough for supporting a shell.

[Possibly it is indeed a shell fossil. Some bivalves are very thin when alive and even thick ones can become compressed flat over time as a fossil. A coral fossil is another possibility. Is there an Indiana fossil collector help us to identify this fossil find? Please leave a comment.]

Could this be an ammonite internal cast?

I found this in a creek bed in Southern Ohio, I am curious as to what it is.

[Editor's Note: We are not certain about this one. It may or may not be a fossil, but it does remind us of the internal structure of an ammonite shell. Any ideas Ohio fossil collectors? Please leave a response.]

A chance find of marine fossils in Indiana.

I was walking in soybean field looking for arrowheads yesterday and found these at the end of a washed out gully or ditch going at a uphill slant. Coral, Brachiopod and sponge I think. Lots of sand also where the water had come out of the gully. These fossils were all close to each other. The sponge or piece with holes is very pretty on the other side with tiny crystals in the formations. Not sure of all names I've stated. Walking up the gully there were larger layers and large rocks with about 3 feet of dirt above them on each side of me as I walked. Each year the gully gets deeper with the rains and the depth is past my waist when I'm walking in it. More rocks are showing up in the bottom of it than were there last year. Although when you drive down State Road 1 it just looks like a dirt soybean field. Now I know there's lot of rock under it with fossils.
