Potential crinoid calyx? Potentially Ordovician?

[ScottBlooded]

Hey everyone, hope you’re all doing well. I was on a walk the other day in a local nature preserve with my son when I stumbled across some fossiliferous stones in a pile. These contained mostly brachiopods, but one in particular had crinoids stems and another structure I wasn’t certain on. I’m not familiar with this place, looking up the area puts it somewhere in the Ordovician (either the conococheague, Stonehenge or stoufferstown formations) but these stones had been deliberately placed in a pile so I can’t say for certain if they came from the location or were brought in.

So I have 2 questions:

1- is the lumpy structure on the one stone a partial mould of a crinoid calyx, or just something geological and

2-are these fossils indeed Ordovician? Essentially I’m wondering if it’s worth my time to come back to this site in my free time to fossil hunt in ernest. I’ve included a picture of the brachiopod hash plate in hopes it would help date it.

As always thank you guys so much for your time!

ps sorry no scale! I was not expecting to find fossils this day and didn’t take the rocks home with me as I felt this would be frowned upon in a nature preserve

Looks like tabulate coral to me.

It's a mold of a Pleurodictyum coral. Either two Pleurodictyum americanum, or a single  Pleurodictyum styloporum.

Also, I believe this would more likely be Devonian in age.

Thank you! See I thought those brachiopods looked Devonian too but after seeing the whole area for miles and miles is Ordovician, I just chalked it up to the old “hammer/nail” thing because I only work in the Devonian. So that means someone brought those out there and dumped them. Strange
