Pennsylvanian seed fern fossils

The following are images of Pennsylvanian seed fern fossils in my collection.  Members of the Fossil Forum have generously provided comments, insights and corrections to many of these images; comments/suggestions/corrections from readers are welcome!  It should be noted species names followed by a question mark indicate that these names are likely but not definitive.  Specimens from eastern Kentucky were found in abandoned coal mines on private farms

I am including images of the following specimens:

1)   Alethopteris serlii(?) from the Pennsylvanian in eastern Kentucky

2)   Crenulopteris acadica(?) from the Pennsylvanian in Mazon Creek, IL

3)   Diplazites(?) unita(?) from the Pennsylvanian in Mazon Creek, IL

4)   Eusphenopteris rotundiloba(?) from the Pennsylvanian in eastern Kentucky

5)   Eusphenopteris obtusiloba  Brongniart from the mid Pennsylvanian  (~310 MYA) in the Westphalian B from Upper Silesia         in Poland

6)   Laveineopteris rarinervis(?) from the Pennsylvanian in eastern Kentucky

7a)  Lyginopteris hoeninghausi is from the Pennsylvanian Pottsville formation in Jefferson County AL  

7b)  Closeup of the Lyginopteris hoeninghausi specimen in 7a

8)    Mariopteris nervosa (?) from the Pennsylvanian in eastern Kentucky

9)    Senftenbergia plumosa from the Pennsylvanian in Upper Silesia, Poland

10)  Sphenopteris spinosa (?) from the Pennsylvanian in eastern Kentucky

11)  Pecopteris(?) from the Pennsylvanian in eastern Kentucky

12)  Macroeuropteris scheuchzeri(?) from the Pennsylvanian in Mazon Creek, IL

 

Lastly I have included one image of a Devonian Glossopteris(?) specimen possibly by Australia?

      Sorry for a little confusion. The fish is NOT Palaeoniscum, it is Paramblypterus... Better to do not too many things at the same time..., photographed and archieved lot of Permian Material from Harz (Kupferschiefer with Palaeoniscum) and Permian Material from Pfalz Region (with Paramblypterus)... So, due to this and because I've always been a bit absent-minded , things got mixed up...
    • Paravian (microraptorine?) tooth

      Interesting, it does look like it could be the same morphology. Too bad the enamel's gone.

      Yes, each photo will be treated as a separate entry in the album, as that is the way the software is configured.

      I meant like how when you go to make a new entry in Collections it provides a ton of fields for you to fill in but it also allows you to add multiple images of the same specimen to an entry so for example if i search "RWC1" it would show a single entry for the rock designated RWC1 like heref

      from the way it looks currently if i were to add additional images to the album each photo will be treated as a separate entry and id have to manually copy paste the specimen data for it to appear on both pictures

      If you mean if there is some kind of template here, then no, there isn't. You just type in all of the detailed info yourself. Simple as that.

      im experimenting atm. just trying to figure out how it works. Is there any way to add entries with detailed info like in the Collections? or adding several images of the same specimen with one overall entry? so the file structure is 
      >collection
        >specimen 1
          >description
           >photo 1
           >photo 2
      instead of
       
      >collection
         >image 1
            >specimen 1
                >description 1
         >image 2
            >specimen 1
               >description 2
       
      with two separate descriptions for specimen 1
       
      there is a description on the other photo of the specimen currently but it doesnt show up on this one
       
      I do want to add detailed info regarding taxonomic id, date, location, leg, etc but first off im trying to establish the structure so the process will be uniform without double entries

      Please add a detailed description here in the body of the text instead of just filling up the tags.
    • Partial Cladodont tooth

      UPDATE:  I now believe that this might be a Ctenacanthus sp. tooth with feeding wear.
