Mystery flat area on hash plate

[Beth929]

What is that flat'ish darker area upper mid left, has ridges?

Looks skin-like to me, I know it's not but I'm curious.

Thanks

We could use another picture from directly above the fossil, rather than at an oblique angle, ... and without so much contrast - daylight, but not direct sunlight.  

 

My first guess from this photo would be some type of bryozoan - there is another next to it to the right.

Now it's on the right...i see tiny dots along the front end of it.

That's all the pics I have of it, sorry.

Hope it helps someway

Thanks

I can see that, but the detail is lacking. 

Could you take the picture from above, ... looking directly down on the item?

 

And what is the size of the item? 

And where was it found?

 

[Beth929]

I'll fiddle around with it in photoshop....

Well, you did a better job I think but this is my attempt

Thank you!

[Beth929]

6 inches X 3 inches

about the size of my LC smartphone.

It's packed away behind junk in my garage, can't get to it.

The fossil is that big, or the matrix?

[Beth929]

no, the whole chuck is that big. the critter is 3/4 of an inch i believe.

I found it at the Fossil Park in Sylvaina Ohio.

Thanks for the cool shots too...

I think it's a tabulate coral. One with a branching colony form. 

[Beth929]

Thanks Rockwood.

I was just gonna say maybe a scrunched up section of Sulcoretepora Bryozoas?

From what Fossildude said and so I looked up "flat bryozoans" and found this link from Views of the Mahantango

"Emmonsia branches are among the most common coral fragments exposed in the upper layers of limestone at the Falls of the Ohio."

Maybe Emmonsia then?

Yes, a tabulate coral as Rockwood has said. Found some hash plates today but not as nice as yours. Great find!

[Beth929]

Thank you John Brewer

Careful, I think the similarity seen here is more in the presentation than anything diagnostic.

[Beth929]

Yes, I'll have to get it out of storage and get better pictures. Thanks.
