5 Mazon Creek specimens that need confirmation or species ID

[Mark Kmiecik]

Calling on the usual members, again, to either confirm or refute my attempt at ID on these five Mazon Creek specimens. Thanks in advance.  @bigred97 @connorp @deutscheben @fiddlehead @flipper559 @Nimravis @Plantguy @RCFossils @Runner64 @stats @TheRocksWillShoutHisGlory

Agree on the Annularia species. The "unidentified flora" is a partial pecopterid pinnule. The venation looks well defined and thus a specific ID might be possible, however I cannot exactly make out the venation. Some closer pictures would help.

I'm guessing you mean J0011 and not J0012. I'll see if I can get a macro shot of it. It's less than 2cm long.

@connorp These are as good as it will get. Thanks for taking a look.

Much better. I would make two observations: the midveins arch irregularly, and the lateral veins fork once at various distances from the midvein. I would label this specimen as Crenulopteris subcrenulata.

Thanks for the info. I can use all the help I can get!
