Crinoids, brachiopod, and...? more crinoids??

Total fossil newbie here.  A few weeks ago while running, I randomly noticed a weird rock that I thought might be a fossil, and some nice folks here helped me ID it as crinoidal sandstone with a few brachiopod impressions.  I figured it was a one-time thing, but when I ran the same route today, I could help but keep an eye out and was shocked to find , now that my brain is primed to see them, that the ground in that area is just littered with crinoids and brachiopods.  I've been running right over them on almost a weekly basis for a couple of decades without ever noticing.  I know these are probably boring fossils for most of you, but I still find them fascinating.  I have a couple of questions about a few details on these that I hope someone will answer. Here's a few general photos of them.  I know the one is crinoid pieces.  I think the other is a brachiopod - is this correct?

And the few details:  is this part just a side view of a crinoid stalk, or is it something else?

And this - another part of a crinoid?  Or something else?

And finally, from the one I think is a brachiopod, it looks like there might be an impression of something else just above it (closup below).  Is this something?  Or just a feature of the rock?

Thanks for any help!

Hi, you're right those are crinoids and brachiopods. For the last one, i see a feature of the rock.

Must be post Ordovician crinoids - those looks like very different branches of the crinoid tree to me. The brachiopods are very poorly preserve being exposed to the elements. Maybe this person might crack open some of the thicker rocks for fresher specimens?

I should have given more info one where these were found - near the top of a mountain in Southwest Virginia.  I just looked at the National Geologic Map Database that someone posted on another thread, and it looks like the area where I found these is Devonian.

Thanks. I also now see that clearly in the picture with the brachiopod. Yes Devonian 100% for sure! I'm not that familiar with Silurian as there isn't significant deposits near where I lives. (Silurian is 100% absent from Minnesota and occurs in smaller regions in Iowa and Wisconsin). So far Silurian seem to be more of transition period from Ordovician to Devonian.
