0lderthandirt Posted November 17, 2017 Share Posted November 17, 2017 Arizona, Redwall limestone, Mooney member. I've found several examples of what look like plants but because they are around crinoids I'm thinking possibly crinoid arms. Anyone know what these are? Thanks Will your next answer to my question be no? Link to comment Share on other sites More sharing options...

FossilDAWG Posted November 17, 2017 Share Posted November 17, 2017 I suspect they are cross sections of bryozoans. Don 2 Link to comment Share on other sites More sharing options...
abyssunder Posted November 17, 2017 Share Posted November 17, 2017 Maybe they are eroded crinoid holdfast parts. 4 " 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.

I don't think this applies to these fossils however this definitely answers my next question to other fossils found the same day! Thank you very much. Will your next answer to my question be no?

I found several bryozoans the same day but I don't see how that can be this at all, the cross sections are very thin, like 1/16th inch with a totally predictable pattern. This has what looks like a vein in the middle of a 1/4 inch wide leaf with little veins coming out on each side. Even the stem going to each "leaf" is about 1/8 inch wide with tiny hairs. That's much thicker than what I thought bryozoans are. If you have a picture of bryozoan that resembles this I would love to see it. Thanks Will your next answer to my question be no?

abyssunder Posted November 18, 2017 Share Posted November 18, 2017 It's a very intriguing specimen! Other possibilities resembling the specimen(s) in question might be my far guesses: Crinoid (or similar) arms (if it was not ruled out from the beginnig), sea cucumbers (which came to my mind) not leaving the echinoderm realm.

0lderthandirt Posted November 18, 2017 Author Share Posted November 18, 2017 I just cleaned up a crinoid on its side that I found today. I see similarities. I'm now leaning towards the fossil being crinoid stems on their side going in and out of the rock, unless anyone is confident in it being something else. Will your next answer to my question be no?

I see what you mean and I think you are absolutely right, not only that this also explains patterns in the large pieces of limestone on my property that are too worn to even be sure they were fossils. Thank you for taking the time to find that! Much appreciated. 2 Will your next answer to my question be no? Link to comment Share on other sites More sharing options...

abyssunder Posted November 19, 2017 Share Posted November 19, 2017 just two more images of crinoid root system, these ones having also portions revealing the internal structure: original pictures from here " 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.
