Found this in Iowa while picking rock out of a field. Pretty smooth on the colorful glassy parts.

Found this in a field in Iowa kinda looks like a stick with a branch and small leaf imprint too

Found this odd rock that looks bumpy with some random smooth rounded parts, maybe fossil ? Idk

I found this in Iowa at a nature reserve near the water, I first thought the rock was just eroded oddly but now I’m now I’m think fossilized coral, what do you all think ?
