Unknown fossil

Summit County Has Devonian rocks in the lower valleys, otherwise the bedrock is Mississippian. Just throwing this out for the experts at identification to use. Also, they will ask for the size and a little more specific description of location. Anyways, VERY INTERESING FIND. I will look on as the answers come in.

Your fossil is an arm (with pinnules) from a crinoid.  The pinnules, which give the arm a feather-like appearance, were used to filter microscopic particles from the water.  The particles were moved down the arm to the mouth of the crinoid, where they were ingested.  Unfortunately the calyx is not preserved, so a better identification of the crinoid is not possible.  Nice find!

That's a great specimen! Having individual pieces of a crinoid makes it easier for study. Good find.

Very nice - and well spotted, Don!

It is a shame there''s no calyx, but it is still possible to do something with some isolated arms. Needs a lot of very detailed work to compare with described species, though, and to be honest it's probably not worth it. Just enjoy. :)

Nice find. You've found some good fossiliferous material there!  I'm guessing lower Mississippian Cuyahoga formation.

Wow. This is an amazing find.
:wub:
Seriously, I'm not new to hunting, and I can't find an arm intricately preserved like that one.
Put it somewhere nice.

There is also some bryozoan next to the arm, ... and a partial shell imprint as well. 

Great find. :)
