I live in SE Missouri, and my little 2/3 acre backyard has yielded some interesting rocks. I've found plenty of crinoids and oolitic chert and even some good gastropods; but there are a few rocks/fossils that I have no clue what they are. Hopefully, someone will ID or tell me it's just a weird looking rock!
Rock #1 - some sort of bivalve? The three upper areas are convex, while the lower circular area is concave. It appears to have layers from the side. (it is just rough on the bottom)
Rock #2 I really don't know what to make of this tooth/horn shaped one. The outer thin layer is crackled, but all the layers under that are very hard, like quartzite, and slightly sparkly. At the right angle, you can see that the lighter inner layer has crystals or columns that radiate from the dark middle to the outside.
Rock #3 This may just be a weird nodule. I love chert nodules and have piles of them everywhere, but none of them have little foot-like projections like this.
Rock #4 I'm 80% sure I got this one in my backyard. If not, it was probably some landscape gravel. This one definitely looks like something. Trilobite? The edge (last photo) even has some interesting cube shapes.
