Nice haul. I like the trilobite. He is just peeking out of the rock.

Maybe Ohio Devonian with Stropheodonta demissa, Atrypa, Mucrospirifer and Orthospirifer? 

But i'm still learning these area, maybe Penn Dixie or even Hungry Hollow. 

Super bargains, Ralph, a lot of quite decent stuff for next to nothing. :)

You got some great deals!  I was thinking of going to the show, but totally forgot about it.

 

Cheers,

Rich

I did a 5 minute pre job on the trilobite and her what was hidden in the matrix.

Here are a bunch of brachiopods and 1 horn coral that I got for a few dollars, but I do not have a location or age on these, If someone can help out it would be appreciated

The two circled below are Paraspirifer bownockeri. The other big ones may be also.  I'd have to have a better look.  Their presence makes the collecting locale to be more likely Sylvania, OH.  That is the only exposure of the Silica that I know of where these were common / abundant .

 

The others are the typical Mucrospirifer sp(p).

Highway robbery on your acquisitions :)

 

EDIT: I just saw your scale cube.  That would be some tiny Paraspirifer bownockeri... but that's what they look like to me.  However their small size does bring that ID into question.

Orthospirifer cooperi, perhaps?

The Turritella agate is indeed from Wyoming.

 maybe, but the sulcus looks a little too Broad and shallow, and the fold on the one is nearly wedge-like, much like Paraspirifer bownockeri.  Need photos from different angles, and a close up of the fold and sulcus so that we can see the surface ornamentation. Paraspirifer as fine chevrons on the fold parallel with the commissure.  O. cooperi has fine striae  parallel with the plications

These are Mucrospirifer, I think we are agreed on these. 

Lovely, though.:)

The third, fourth and i think the last photo are Stropheodonta demissa and 5 and 6 are Atrypa. Again, i think we agree.

But it's the one at the top, the first couple of photos here, the ones circled in red by Tony that we are not sure about. 

Lovely.:wub:

With the new photos, I believe the ones in question are in fact Orthospirifer cooperi as Adam surmised. I can see fine costae (capillae) on the fold, parallel with plications. It's amazing how things can look so differently from one photo to another. None of these seem to have the tall, acute fold like what I thought I was seeing on the original photos. (Maybe it was wishful thinking, as I love Paraspirifer bownockeri. My absolute favorite brachiopod :o)
