Devonian shale in WV, Lost river fossils

[SallyB]

After some awesome advice from FF members, my family made it out to the Lost River quarry in WV (Devonian shale). We found a bunch of bivalve and trilobite partial fossils and two fossils that we can't ID (pics below).

The first was found in a split piece of shale so one part mirrors the other (pieces are ~3x3in). Unsure if this is a fossil but any insight is appreciated! 

The second is a very small (1/4in) circular, striated fossil. 

Thanks!

I would guess the first is an oxidized trace fossil (such as a worm burrow), and the second is a crinoid columnal.

Hi Sally,

 

I'm heading out that way soon to check out a couple of other sites, but I've driven by the Lost River so many times, I'd like to stop by this time.  Can you share any of the awesome advice you received about searching there?

 

Thank you.

 

Eric

When I was last there the trilobites were high up and on the right side of the cliff.  Remember the quarry is on the old road
