t-tree Posted July 16, 2016 Share Posted July 16, 2016 Nice find ....it reminds me of Cordaitanthus sp. John Be happy while you're living for you're a long time dead. Link to comment Share on other sites More sharing options...
abyssunder Posted July 22, 2016 Share Posted July 22, 2016 Looks like Cordaianthus to me. https://www.fieldmuseum.org/node/5126 http://fossilworks.org/?a=collectionSearch&taxon_name=cordaianthus&max_interval=Carboniferous&country=United%20States&state=Ohio&is_real_user=1&basic=yes&type=view&match_subgenera=1 Upper Pennsylvanian Compression Floras of the 7-11 Mine, Columbiana County, Northeastern Ohio - McComas, Melissa Ahttps://kb.osu.edu/dspace/bitstream/handle/1811/23238/V088N1_048.pdf;jsessionid=04E6EB8774EFD07BC5C943888562155E?sequence=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.

saysac Posted July 22, 2016 Author Share Posted July 22, 2016 Abyssunder I believe you are correct! Looks exactly like it to me. Can you tell me what it is from? I assume it is the seed? Sherry Link to comment Share on other sites More sharing options...
Fossildude19 Posted July 22, 2016 Share Posted July 22, 2016 Abyssunder I believe you are correct! Looks exactly like it to me. Can you tell me what it is from? I assume it is the seed? Sherry, I looked at the PDF abyssunder posted - it lists the Cordaianthus under Cordaitales. The same order that includes Cordaites. And yes, these would be the seeds/cone?.

abyssunder Posted July 22, 2016 Share Posted July 22, 2016 Yes, looks to be that, the reproductive structures of Cordaites.http://www.ucmp.berkeley.edu/IB181/VPL/CorCon/CorCon2.htmlhttp://www.georgesbasement.com/Langford-WilmingtonCoalFlora/Webpage/CordaitesPP44-45.htm " 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.

doushantuo Posted July 22, 2016 Share Posted July 22, 2016 I don't suppose anyone has noticed the multiple Cordaites revisions online? Isn't Cordaianthus a form genus? Link to comment Share on other sites More sharing options...
abyssunder Posted July 22, 2016 Share Posted July 22, 2016 As it is stated in the first link of post #7 :" The form genus Cordaianthus includes both pollen- and ovule-bearing strobili. (...)

saysac Posted July 22, 2016 Author Share Posted July 22, 2016 Thank you everyone. When I googled Cordaitanthus, this link came up, and I found it very interesting. I found these "circles" which have yet to be identified, and wonder if all of you can take a look at figure 481 and see what you think? It definitely resembles the figure, at least to me....

abyssunder Posted July 26, 2016 Share Posted July 26, 2016 I believe you are correct. Also, the one on the right side of the first picture, could be one in longitudinal/lateral view, like D in the document page.

saysac Posted July 27, 2016 Author Share Posted July 27, 2016 Thank you so much abyssunder for looking at this and giving your opinion. I have thought that the "circles" were perhaps looking at a cross section but when I saw the view on the document I really think it is the same. Thank you very much for your confirmation! This is pretty exciting for me! Sherry Link to comment Share on other sites More sharing options...
Stocksdale Posted July 27, 2016 Share Posted July 27, 2016 I don't think they are the same. The pieces on the outside of your circles don't look very foliar (plant-like) to me. But I could be wrong....... My personal leaning for the circles are that they are a microbial or algae mats like a stromatolite but a little different since it was freshwater. Now some circles could also be different things. And I could be wrong. They might be a cross-section of a stem or some plant part. I'd posted a thing in Researchgate on the circle-things and received a few responses. But nothing very definitive. https://www.researchgate.net/post/What_are_these_circle_things_Armoured_Mud_Balls_or_something_else Somewhere, something incredible is waiting to be known.–Carl Sagan Link to comment Share on other sites More sharing options...
saysac Posted July 27, 2016 Author Share Posted July 27, 2016 Well Paul. you may be correct. Now that I read the description it appears that the photos are very small portions, not the root as I was thinking. I have no idea again, but really thought it looked like it. Does anyone know if there were plants like modern cane that were hollow in the middle? Sherry Link to comment Share on other sites More sharing options...
abyssunder Posted July 27, 2016 Share Posted July 27, 2016 The isolated "circles" looks like they are cross section of something and are embedded in the matrix . I don't think that stromatolites could be like these, so I remain in the Cordaianthus assumption.

Stocksdale Posted July 27, 2016 Share Posted July 27, 2016 Ok. I'm having second thoughts on this. I think you two could be right with the cross-section of Cordaianthus. (or cross-section of something else) It would make much more logical sense with the abundance of Cordaites at Sherry's location. I still think the shape looks too "rocky" (for lack of a better work).... like bits of stone as opposed to an impression of a cordaites "flower-cone".

saysac Posted July 28, 2016 Author Share Posted July 28, 2016 Paul, do you have links that show what the outside of the stem or trunks look like of what I have been finding? Sherry Link to comment Share on other sites More sharing options...
Stocksdale Posted July 28, 2016 Share Posted July 28, 2016 Could some of them be cross-section of a pith of a small Cordaites branch? http://www.skamienialky.nazwa.pl/galeria/polskaeng.html Somewhere, something incredible is waiting to be known.–Carl Sagan Link to comment Share on other sites More sharing options...

Stocksdale Posted August 9, 2016 Share Posted August 9, 2016 Thinking about these circles.... could they simply be bubbles in the mud surface? The area was likely a valley inundated with freshwater to the point where valley sides form a mudslide. I would assume pockets of air would be trapped during a mudslide. Just a random thought....
