all of these rocks, except for one are very sparkly. they all look way better in person, excuse my camera. they all look as if they were formed by a very strong heat source and have small gold pieces on them. some smell strong like copper and all of them are quite heavy for their size. the three small ones look like fossilized snail shells.  i found a whole bunch of these near the mississippi/alabama border. i have never seen anything like these. any info on what these are will be greatly appreciated. thanks. mike.

They look a bit like coprolites to me- literally fossil poo.

I might be wrong though. 

The gold bits are almost certaintly pyrite, but to be sure, are they cube shaped crystals(you may need a handlens) but I think matt is right, they do look a lot like copralites.

some of them have to be coprolites!

one day i will make a toilet seat out of corpolite!!!!
