Ruger9a Posted December 1, 2019 Share Posted December 1, 2019 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!

Al Dente Posted December 1, 2019 Share Posted December 1, 2019 Not a crinoid. Looks like a sponge. 6 Link to comment Share on other sites More sharing options...
Rockwood Posted December 1, 2019 Share Posted December 1, 2019 The modular look is a bit like crinoid plates. I can see it being a reproduction strategy in such a simple being. 1 Link to comment Share on other sites More sharing options...
Ruger9a Posted December 1, 2019 Author Share Posted December 1, 2019 Thanks for your help guys, but I'm kinda lost, sorry. Is it a Sponge? Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted December 2, 2019 Share Posted December 2, 2019 Yup, I'm fairly certain it's a sponge. Very nice specimen too. 3 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Ruger9a Posted December 2, 2019 Author Share Posted December 2, 2019 Thanks, any idea what species? Or should I just put it back in unidentified draw? Link to comment Share on other sites More sharing options...
Ruger9a Posted December 2, 2019 Author Share Posted December 2, 2019 Should I try to remove the rest of the matrix in the throat or leave it as it? Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted December 2, 2019 Share Posted December 2, 2019 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. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Ruger9a Posted December 2, 2019 Author Share Posted December 2, 2019 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... 1 Link to comment Share on other sites More sharing options...

Carl Posted December 2, 2019 Share Posted December 2, 2019 I, too, see a sponge. And don't apologize for questions like these! This is what we are waiting for! 2 Link to comment Share on other sites More sharing options...
Ruger9a Posted December 2, 2019 Author Share Posted December 2, 2019 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;) Link to comment Share on other sites More sharing options...

Ludwigia Posted December 3, 2019 Share Posted December 3, 2019 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. 2 Greetings from the Lake of Constance.

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. Link to comment Share on other sites More sharing options...

I have a few sponges and I can see detail with just a 20X loop magnifier. 3 Link to comment Share on other sites More sharing options...
abyssunder Posted February 24, 2020 Share Posted February 24, 2020 The specimen looks like a aponge to me also, so I'm in the camp of those who have the same feeling.:) 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Ruger9a Posted February 26, 2020 Author Share Posted February 26, 2020 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. Link to comment Share on other sites More sharing options...
mikeymig Posted February 26, 2020 Share Posted February 26, 2020 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. led zeppelin Link to comment Share on other sites More sharing options...
