I have never seen anything like this or even close.

That said most everything about it is a mystery. Had the granddaughter out at a playground in Spring Valley with a lot of pea gravel as a base, and I started finding these bryozoans and this.

This city is really cheap, so this pea gravel is local. Pea gravel is not Ordovician, we do have Devonian in the SW corner of Fillmore County and a number of gravel pits. But we also have Cretaceous in the west which also covers Spring Valley. And then there is the possibility of ice age as we have a lot of glacial till. Yes, I know this isn't helping and that is why I'm showing you the bryozoans with this.

So a couple of more pics of it:

And then there is this one... The pores make me think bryozoan, but...

The back

And for scale I'll have to go to a reply...

So if anyone has a clue even on possible age of these fossils I would appreciate it.

I've just never seen anything like that first one!

Thanks for taking a look! :)

A siphuncle that is curly? I thought they were tube-like. Any thoughts then on the period it may be from?

Mould of the hollow inside a crinoid stem, with the stem dissolved away?

I agree the second looks like a bryozoan.

It sounds like this may end up in the unknowns pile. :(

But it is also sounding like maybe Devonian???

I truly appreciate all of you taking a stab at it! Reminded me of an Archemedes bryozoan too when I first looked at it, but I have only examples that I have purchased as I don't think we have them in the Ordovician.

For those of you who may be interested in this hunt, there were actually 3 that day :) I have created a post about it on my blog, however it is grandchild heavy. :-D

Another possibility for the first rock is the inner core of a snail shaped like hormotoma, with the cavity revealed where the thin portions of the shells outer whorls dissolved away. I think I see some spiraling grooves imprinted on the inner surface of the cavity. The spiny cone with a mesh top reminds me of chancellorid sponges like pirania, or Allonia, but I think those became extinct in the early Ordovician.
