Strange fossil found in rock piles near a pond in Port Byron, Illinois.

This strange fossil was found in rock piles near a pond in Port Byron, Illinois. I believe the snail was found there too, possibly in my backyard in Port Byron not the pond though.

Possible Illinois trilobite or crinoid fossil

Any suggestions as to the type os fossil this is? Please post your ideas with the response button below.

Fossil mandible found in Florida.

Perhaps it is a Tiny Mandible? "This was found along the shore at Madeira Beach Florida during a sudden rain storm on 7-18-10. At first we thought it was a small tooth of some kind, but on closer examination with a magnifying glass it resembled a tiny mandible! There appears to be a single tooth socket at the rear of the bone. It is totally unusual!"

What are they? I have no clue?

I got these yesterday at an auction in Eaton, CO. I couldn't pass them up, but I don't know what they are. What are they? I have no clue?

Is this a dinosaur egg?

British Columbia dinosaur egg

I was wondering what this is ( assuming it is a dinosaur egg ). Found this in interior British Columbia in a coal mining area. Was told it was a natural formation which is sometimes found, but I doubt the source of that. Could you please ID it for me. Would it be worth cutting it open to see if there was anything inside?

Location: British Columbia

Unknown fossil mammal tooth from Florida

I need some help with this one from some Florida fossil hunters. I found this Pliocene mammal tooth in the Gardinier Phosphate Mine (later the Cargill Mine) and it is likely from the Bone Valley Formation. You've got to love that formation name! It was legally collected many years ago, but I have never had a proper ID on it. The tooth is about 3/4 of an inch long, although the end is broken. Does anyone recognize it?
