Crinoid cemetery and Bryozoan bits & bobs

[Rogue Embryo]

I know crinoid "forests" are a dime a dozen, but still its nice to find one so packed . . .

And some bryozoan pieces, my first that I can identify with a bit of confidence . . . but please correct if I'm mistaken.

 

 

Cheers!

You’re right, those crinoids are sure packed tight! And the last two pics look like bryozoans to me also.

Yep. Nice crinoidal limestone and bryozoans.

So, at a dime a dozen your slab is worth..oh, wait, no valuations here.

But, yes often overlooked, crinoid debris is still special.

And I just noticed something up-close among the crinoids - a little black piece that reminds me of scolecodont. Ever since Monica posted some great specimens recently, I've been poring over my fossil rocks to see if any are there. What do you think? Am I just imagining that I see some little teeth and the curve of a jaw?

I realize that the black parts are pretty degraded and unclear. Sometimes when I'm out seeking fossils, my mind sees fossil patterns that on closer examination turn out to have deceived me. Funny how the mind "wants" to see or hear something and so creates it. Like hearing music in white noise.

Those bryozoan colonies had to have looked a little like a Charlie Brown christmas tree.

These pieces are often packed with little surprises.

Sometimes it's hard to keep in mind that most bits in a piece like this are seen at a bizarre cross section angle, not as they appeared in life.

I think they're trace fossils. I tend to find a lot of burrow fossils on the underside of limestone hash that's surrounded by shale.

That thought crossed my mind too. We’d need to see a closer, sharply focused image to see whether there are any details suggestive of biological form to be sure they’re bryozoans and not trace fossils.

You would be mistaken. 

 

They are clearly bryozoans:

Hard to tell from this picture. You knows some trace fossils have short lines on them.

I do.

And I also know when I am looking at cross sections of bryozoans, ... which I believe I am seeing here.  

I agree, better pictures will show us for certain.

Ok I agree with you. I'm not going to push it aggressively since its a different formation thus different biochemical, etc.
