Crinoid#1 ID help needed


Ruger9a

Recommended Posts

Hey group.  I hope you're not getting tired of answering all my questions.  Because...... I am requesting your expertise in a few more crinoid identifications.  The information (as listed) I have on this specimen is it a  Devonian Crinoid Flower from an estate sale collection from the early 1960's.  It's listed(?) find location is Iowa, USA.  It was originally purchased from Ralph E, Mueller and Son Phoenix, AZ in the early 1960's and was displayed in their store for several years until being sold.  Help please!

The modular look is a bit like crinoid plates. I can see it being a reproduction strategy in such a simple being.

Thanks for your help guys, but  I'm kinda lost, sorry.  Is it a Sponge?

A sponge can be put through a sieve and it's cells will reorganize into smaller sponges.

I've no idea as to the species and, yes, I would gently try to remove the matrix with a pin vice, see what happens.

Sorry about the silly questions guys.  I freely admit "I don't know diddly nor squat" about sponges.  Except SpongeBob because I had to sit through so many episodes with the Grand Kids over the years.  I assume you did as well, right Grandpa? LOL

Rockwood, thanks for putting your response in layman's terms.  I only have about 5-10 sponges in my entire collection because I don't understand them or the varieties.

Tidgy' dad, Thanks for the advice on further detailing, I always wondered what was in there...

What I saw was a video of the actual experiment in condensed time.

I doubt Mr. Green Jeans could have pulled that one off.

Well, I guess I CAN move this from the unidentified draw to a display shelf after all.  Thanks so much for your time and patience.  Opps, Did I say display shelf...…  Don't have any with room on them and the missus won't let me start another.  Hummmmmm, this action may require some strategic planning.  I may have to contact Mr. Green Jeans for advice;)

If you're planning on scraping off some matrix, then look through the microscope to see if you can discover any spicules. For one thing, this would confirm the id as sponge and they can apparently also be helpful with identification altogether.

Ludwidia, I don't have an electron microscope or even a decent microscope to assist in the confirmation of spicules in the matrix.  So, I may just have to resign myself to the fact that it will remain an unidentified species of sponge.  Thanks again.

Spicules are not necessarily that small. I have a few sponges and I can see detail with just a 20X loop magnifier.

The specimen looks like a aponge to me also, so I'm in the camp of those who have the same feeling.:)

Ok  folks.  The matrix was too hard for me to get out with a pick and my dremel tool is too wide to fit into the aperture.  So, I did the next best thing and took some close up photos of the maxtix contents.  Hope this helps those interested in the matrix.

Found its double here in the Devonian rocks of New York. I thought at first that it was a crinoid calyx as well. It turned out to be the heavily mineralized section of an exploded nautiloid shell. I think you have the same type of fossil here.

Many times I've wondered how much there is to know.
