Hey there Scotto, Welcome to the forum! Thanx for taking a peek at my little, who knows what in heck these creatures are? Hopefully someone in here will scope them out that knows what they are or point me in the right direction to look 'em up.
Hope to see some of your posts in the future. Don't be shy, it's a pretty friendly place. 8)
It looks like a conglomerate of bivalves and possibly other marine "shelled" animals. Looks very similar to the fossiliferous shales and sandstones I see often in my area. Im not palentologist though, so dont take my word for it. I just like fossil hunting. :P
