Hi guys! I have a few fossils found recently that are not identified yet.

The first is thick and looks like half of a round object. I found it near Payson AZ. The second wasn't too far from the first. It may be coral from what I can tell. The third is from a place called the Paleo dig site 13 miles from Payson. It's a conglomerate of many different sea mollusks I think? There are at least 4 different looking shells I found all around the site that seem to be agatized. Any help id and for the conglomerate of shells, how do I safely remove the mudstone or limestone to expose the shells more? So far I've used a soft toothbrush to brush away the junk.  I've included 3 angles front and back. The last conglomerate has fossils on both sides. Side #2 looks like sea daisy's maybe?

The "back" side of the hash plate pictured last shows many fenestrate bryozoans.

The front shows some bivalves and possibly brachiopods.

Thank you!

The rocks from the Kohl’s Ranch area Paleo Site are the only ones with definite fossils. The hash plates probably deposited during storms contain mostly brachiopods, bivalves, bryozoans and crinoids.

 

Clean them with warm water, soap and a toothbrush. You also can use hydrogen peroxide from the grocery store.
