Is the a Saccocoma?

[GeschWhat]

Hi all,

 

I was playing with my poop a while back, as one does, and discovered a hidden treasure. I prepped out what I think is a nice little floating crinoid. It looks beefier than the Saccocoma in my collection. Can anyone verify that is what this is? Thanks a bunch!

Here's a magnified view.

I agree it is more compact and has fewer arms than would be expected.

I don't actually expect it will be a help though.

I would say that this is, as you put it, a somewhat beefier Saccocoma than normal with, as Rockwood mentioned, a few missing or jumbled arms. Here's a website with Solnhofen crinoids to help out.

I think that with the spines (and five arms) it could be a Sinosura ophiuroid, maybe a juvenile?

Sinosura would be a good ID in my thinking.

By George! I didn't think of that one. You guys are right!

So I must be looking at the underside? Here is a closeup of the center. That would be called the disk, correct? For some reason I was seeing seeing more arms that were actually there.
