What is this a fossil of?

[slydog]

Can anyone tell me what this is a fossil of? I found it in the creek running through our land in Greers Ferry Arkansas Well, my wife calls it a creek, I call it an expensive drainage ditch. Either way, it's beautiful and serene. This looks like some kind of bud, or plant head. The underside(next posted pic) assuming I am looking at it from the correct perspective, looks to be maybe where a root ball was?? I dunno. It kind of resembles a flattened garlic bulb, or a very smal squashed squah kind of thingy, who knows /forums/images/graemlins/confused.gif Anywho, if anyone can identify it, I'd like to know what it is. I'd hate to think I've been proudly showing off an old dinosaur turd! /forums/images/graemlins/grin.gif

Looks like a sea urchin to me.

Maybe these guys can tell you what you found.

It looks very much like a sand dollar.

My best guess from your pictures is a gastropod (fossil snail) or an ammonite (fossil squid-like animal that grew a spiral shell), but it's hard to say from here. From the second picture it looks to have a spiral structure. If it had pentagonal (five sided) symmetry it would be a crinoid, a platy animal that was rooted to the sea floor and filtered trash from the water that floated by, but it doesn't look like it from your pictures.

Sorry, hard to be more specific without seeing it in person or more/better pictures.

My first impression was that of a sand dollar. But the second picture made me somewhat unsure.

Looks like a little fossilized cow pie.

This Would Be My Guess..................

Given the very small size, and given that it looks to be hard as a rock, and I'm just guessing that it was as cold as the stream when you found it, I would suggest that is the heart of a "mother in law"

And if that is what I suspect, then it is not a fossil at all. It is a modern day M-I-L heart that was simply discarded from lack of use.
