Cool I’ll look those up! I remember when I was in elementary school, I spent recess digging in a gravel pile with one of my friends who told me to look for them. I was probably in 4th or 5th grade, and obviously had no idea what I was doing! I don’t know what we did with them after, probably left them in our pockets and forgot. (and I can imagine 30 years from now finding the jacket I used to put them in)Your little cork shaped ones are crinoid fossils. View attachment 2445881
I guess I haven’t changed much since then, since I still just pick up the “weird ones” and put them in my pocket without asking what they are
