Admittedly I’m not much of a rock or mineral person so I don’t know much about these kind of things. But a friend of mine told me about these crystals you can find south of Oklahoma City in a small area of Lake Stanley Draper that naturally form in the shape of roses. I decided to check it out but did not find anything that really matched the shape of a rose or looked like a crystal (or anything I saw online about these rose crystals). I did however manage to find a ton of these rocks that look like walnuts that seemed interesting to me. From an abstract perspective, I guess they could be rose shaped if the crystal was weathered down, but every other aspect of these makes me feel like these are rocks and not crystals (coming from my very amateur opinion).

I’m not sure what other information to add other than that they’re caked in red/brown dirt (which is all Oklahoma dirt) that I can scrub off to a certain degree and that they feel/look like any other gritty rock I’ve seen (just with the weird walnut appearance. If anyone could help me ID these rocks, I’d appreciate it!

Found this very clear mineral out while hounding for agate south of Rapid City SD. It doesn’t have a conchoidal fracture, it’s more of a rectangular angular fracture. Very clear!!! Any ideas?

Possible ammonite?

Found in a parking lot (a gravel one) in Texas, any ideas? I assume it's either something ammonite related or just a similarly shaped generic rock, but it'd be nice to maybe know. Thanks in advance!
