trying again for ID

I know I posted this once before but I`m gonna try again. This is almost centered in a 4 inch thick piece of petrified creek or ocean bed. The height that you see in picture is total thickness of piece. Any help anyone? I`ll take some more pics tomorrow of brachiopods and other trace and complete fossils in surface.

I think it looks like some sort of fish impression with multiple fins on top. Is the fossil still in there? I don't know what kind of little fish lived long ago, but it's interesting. It could also be eel-like because some have small taillike structures and top fins. from this picture I see a pig like nose? and possibly one fossil on top of another. It's hard to tell from a picture sometimes shapes blend in. I know for sure it isn't fryable anymore, but it probably could be ground into minerals.

That's going to be tough to identify because it looks like the "fossil" has eroded and weathered away a little bit. I'm not familiar with marine evolution, sorry, JSpencer.

Can you at least give me an age of the rock, then I might have a better idea of possiblities?

Where was it found? In situ? As float? And what is the age of the strata... could help with the ID. Good luck.

Cheers!

This piece as well as many others were collected from the surrounding land, which is in Hondo, Tx. south of San Antonio. These flat rocks were the pioneers version of pavers to give them a path from the home to the outhouse and back without walking in mud. My in-laws had a deer lease there for about 30 years before we gave it up. According to geological map this areas formations are Paleocene to Eocene. Here`s another pic of face of same piece. One day I`ll get to going through the ton or more of these pieces stacked up at my in-laws house.

here is pic of what looked like burrows of some sort on the surface and edges of rock

From the new pics, the blocks appear to be limestone with little bits and pieces of marine shells in them.

J, if you take a closer look, can you see anything that looks like a wee clam or seashell?

Oh yes, the second picture shows how the surface is littered with halves of bi-valves as well as brachiopods. I can send some macro photos along here tomorrow that may help. Thanks

This is pretty much what the surface is littered with. I suppose that this would have been the bottom of the rock since shells are normally face up when they come to rest.

These are the brachiopods contained in surface.
