Mark Kmiecik Posted February 15, 2022 Share Posted February 15, 2022 (edited) A couple of head scratchers and three that I would have called Pecopteris in the past. Calling on the usual MC gang @stats @deutscheben @bigred97 @Nimravis @fiddlehead @flipper559 @connorp @RCFossils and anyone else who would care to take a stab at ID.

Nimravis Posted February 15, 2022 Share Posted February 15, 2022 I am with you on the name Pecopteris , I cannot get into the new names and I still like to call Mazonomya mazonensis , Edmondia or clam-clam. I have no clue what the second pic is, if anything at all. 1 Link to comment Share on other sites More sharing options...

I have no clue what the second pic is, if anything at all. What do you think of the 4th one? Have you looked at an enlarged view of it? There seems to be more than coprolite there. The second one is an oddly-shaped lump inside of a concretion shaped like what you would expect to contain a single Macroneuropteris pinnule. Edited February 15, 2022 by Mark Kmiecik added info Mark.

Mark Kmiecik Posted February 17, 2022 Author Share Posted February 17, 2022 (edited) Would appreciate your opinion on genus and possibly species ID on any of these. I would like to put an accurate label on these if I can. @bigred97 @connorp @deutscheben @fiddlehead @flipper559 @RCFossils @stats @TheRocksWillShoutHisGlory Thank you in advance for any help you can give me. The recent changes in nomenclature of what I used to know as Pecopteris have thrown me for a loop. I'd love to get at least down to genus on the plant fossils.

stats Posted February 18, 2022 Share Posted February 18, 2022 (edited) I think the first 2 ferns are Diplazites unita and the last one is Crenulopteris acadica. All those pecopterid varieties are mindnumbing.... It's all in the veins and veinlets, if there are any and how many. Then, it matters how the veinlets meet the edge of the pinnule. I'm sure @fiddlehead or someone else will correct me here. Cheers, Rich Edited February 18, 2022 by stats 1 1 Link to comment Share on other sites More sharing options...

You've hit the nail square on the head with this statement. Thanks for your input. I was thinking Diplazites on the first two as well but really have no clue on the third. Edit: The third fern (E0095) has pinnules with a crenulated margin. Edited February 18, 2022 by Mark Kmiecik fix typo & add info Mark.

Plantguy Posted February 19, 2022 Share Posted February 19, 2022 Finally got the new book this week and its gonna be a long while before I read it all and even more time to digest and understand/retain any of the new stuff/revisions. Its quite fascinating and I love all the photos/examples! Nice Jack! Been staring at 3 for awhile and I'm wondering what's going on in this area below...seems to show the lobes and has some of the veination and splitting we need....I'm not sure if Fig1 on page 90 is similar or dissimilar to your specimen. Ill tentatively go with Crenulopteris as you all have already stated. Wish the preservation was sharper.. Will wait for the better versed to supply a definitive ID... Nice finds!

Mark Kmiecik Posted February 19, 2022 Author Share Posted February 19, 2022 Thanks for taking a look, Chris. I've had the book for a couple of years (almost?) and I've begun to wear out the spine, but I'm still extremely shaky on the Psaroniaceae, and I've got a boatload in my collection, hopefully less than it takes to sink it. I wish I could post photos that show what I can see thru a loupe at 10x or 15x, but I can't afford the hardware to do that. Thank you again. Mark.
