Pinnules and echinoid spine?

Recommended Posts

Hello again,

I find these crinoid parts (I think) all the time and just want another opinion on what it is. I think number 1 is crinoid pinnules. Number two is the first and only one of these I've found so far here.(Mississippian redwall limestone, Mooney member). It's about 1/4 inch long and I'm guessing perhaps an echinoid spine? I appreciate any input you guys might offer. Thank you

Bob

 along the top edge it looks like bryozoan but the main feature of the rock, just above the number 1, with like two stems and all the little branches? Any idea what kind of bryozoan that might be, it doesn't seem to match anything I can find?

It's hard to tell just which way the colony was oriented, but I think that it is essentially the axis of it. It's preserved as both an external mold (top), and internal molds (casts) of the zoeciia.

It would surprise me more if you could find an example that looked just like it.

I thought number 1 would be a very common well known "something" and I was embarrassed to even ask. I've probably got 50 examples just in boxes of fossils that I've collected but not examined yet. Number 2 I guess I'll just assume is a echinoid spine until someone says otherwise. 

Thank you for your opinion and for the new word "zoeciia" !

Oops! I didn't notice the extra i in there. It's zoecia.

The lack of other opinions does have me wondering.

Just wanted to add another rock I found yesterday that's just packed with this bryozoan for anyone that might be searching for what it is or has an idea of what kind of bryozoan it is.

I just found this that I think not only confirms it is bryozoan but I posted a picture a few years ago that matches the top picture here that @FossilDAWG correctly id'ed as bryozoan. I thought the two were related back then too but really didn't know for sure. You guys "rock"!
