Are these crinoid pinnules?

My wife (the one in our family with the "fossil eye") found this on August 10 on our trip to central New York - we were looking in a very low strata (about 20 feet lower (deeper) than the Devonian "Tully limestone" strata) - this lower strata was a thick (15 foot) layer of very hard blue-grey and orange rock (lots of iron in the shale). There were very few fossils in the layer, a few shells and crinoid stems.

We had given ourselves 10 more minutes and I told Nancy, "Let's try to find something really special before we go." A few minutes later she came up to me and said, "How about this?" Again, her keen fossil eye had found something unusual. These look like a really good preservation of crinoid pinnules, but I would appreciate confirmation.

Are these crinoid pinnules?...

That, or even brittle stars...

Fabulous, either way!

WOW Those are soooo nice :envy:

Very nice! I think you (and others here) are right about this ID.

:envy: I've never found any crinoid pieces other than stem sections. Looks like you had a very good trip!

Nice!!

It's good to have someone in the family with a keen eye for fossils.

And Mediospirifer - I'm with you. That is all I've ever found, also....stem sections of all different sizes.

We did have an incredible trip - only a day and a half but the first day we found a dozen trilobites, a large branching bryozoa, cephalopods with shells and internals, a really interesting large bivalve internal (at least that's what we think it is), and some beautifully preserved soft tissues - including the crinoid pinnules shown here and these strange fossils that have the same shape as Neuropteris fern leaves:

Here is the branching bryozoan:

Here are the 3 separate leaf shaped fossils - these are all on the same large stone we collected, along with other marine creatures:

We also revisted our Devonian tree site and found more Devonian tree shoots including one fossil in situ that included a vertical stem with a long branching stem (or root) coming off of it and other stems/roots. Will post more on that later - am cleaning and processing those finds now.
