Not a clue here, please take a look.

Not a crinoid holdfast or root. 

That looks like the bryozoan, Taeniopora exigua.

 

Shales from the Mahantango formation are sometimes so full of fossils, they end up being cross bedded, and not splitting properly.

I agree with Tim about the tabulate coral Pleurodictyum, that was my thought also.
In the above picture might be a branching *bryozoan mold, at least that's what I think.

I don't see any Tentaculites like creatures, or imprints of them.

 

*Tim said it before.

This might be some of forked rooting of the Crinoid, possibly ? Each fork disappears into a hole in the shale.

 

Several of these chunks are riddled with similar holes and tunnels, I may break into them later.

Agree with Tim, this one is a bryozoan. But it is not the same as the first piece of this thread.

 

@Rocky Stoner - You have a nice site in Your Yard!

[Rocky Stoner]

Thanks to all for responding, I can label these now.

While I have your attention, I found two more of interest.

One is a much larger example of the earlier coral (beside the earlier one for reference). Maybe explain the two concanve areas. One with the coral, and the other one empty.

Maybe these were two halves of a shell ?

 

And the next photo shows a very dimpled surface. Maybe the Crinoid ?

Thanks again folks ... very much !

"Textured" pics. .....

There must be a time restriction or someone else must post before I can send more pics.

Will try again after this post.

There is a 3 meg limit per post. If you make another reply You should be able to add more pictures.

If that does not work then "refresh" the page.

[Rocky Stoner]

Thanks ynot, trying again after refresh.

 

"Textured" pics ....

 

[ynot]

I think that is another bryozoan.

But wait for others to chime in on it as inverts is not My forte.

[abyssunder]

The previous set of pictures shows very well the Pleurodictyum behavior, probably it depends on the preservation status and the point of view.

 

Bryozoans are trying to encrust everything they consider to be a good support for their living, including stromatoporoids (which make the same thing).

 

BTW, you have good pictures.

[Rocky Stoner]

Thank you for helping to sort these into their proper groupings.

 

Now, one more please, before I get reprimanded for destroying the yard ......

 

The following is a chunk I split and "bookmatched" for the photo.

Very busy inside with one unique feature on the lower right side that I haven't seen yet.

Does anyone recognize it ?

I tried to get a better pic, but cannot get the camera to focus at the bottom of the recess.

I'll be off to the other yellow shale plowed patch tomorrow. Hope it rains soon and washes up more of the Orthoceras.

Not positive, but I think it is the print of a crinoid calyx.

[abyssunder]

The vertical one (pic.2) is a crinoid (cystoid) column infill, the next one is an echinoderm calyx imprint, possibly crinoid or cystoid.

[Rocky Stoner]

Looks sort of like Crinoid Calux, but am not sure.

Just saw your post ynot, I'm with you, thanks !

[Rocky Stoner]

Thanks abyssunder, you both posted while I was preparing.

the references to the crinoids mention 5 sided, this one looks to be 6 sided which threw me off a bit.

 

[Fossildude19]

Either a cystoid or crinoid calyx for this one, I think. 

 

 

 

[abyssunder]

Maybe these two topics would help a little:

These dimples appear to be oolithic limestone.

I think this is yet another example of some sort of bryozoan, ...not oolitic limestone.  

Possibly Atactotoechus fruticosus, or Leptotrypella quadrangularis.

 

Mahantango Formation in West Virginia.

 

Not allot of Limestone in the Mahantango in WV.

[Rockwood]

Aren't the dimples on a centimeter scale ? The millimeter scale features look more dome shaped or spherical to me, and there seems to be a greater variance in size than would be expected in places. 

[Plax]

looks like sponge or coral impression but can buy bryozoan. We need a close up of the detail of the dimpled surface.

[Rocky Stoner]

Here are a few attempts at close-ups.

Mold of a tabulate coral.

[TqB]

I think Tim @Fossildude19 is right, mould of a bryozoan with monticules.

Of course. If I hadn't been in such a rush to get back to work I may have paid more attention to the size of them.
