Insect wing or Cyclopteris?


Strepsodus

Strepsodus

I found this fossil today when splitting upper Carboniferous nodules I found earlier this year in West Yorkshire, UK.  I can’t decide whether this is a Cyclopteris leaf or an insect wing.  I think Cyclopteris leaf is more likely but I’m not sure.  It measures 2.5cm long.  Does anyone know what this is?
Thanks,

Don't think it's a wing. I'm not seeing any indication of veins & it looks like it might be a bit too thick. But I could be wrong. :shrug:

Thanks for the comment.  I think you are probably correct.  There is one area of possible veins but I forgot to take a clear photo of it.  Here is a low quality photo.  I will take a better photo tomorrow.

Don't insect wing veins normally form closed cells? I don't see any here.

I believe so.  There are some closed cells on the part in the above photo but they are not very clear on the photo.

A Cyclopteris  will have radiating veins, but none will come back together to form a closed cell. I see some branching in the specimen, but none that come back together. Of course it may be some other plant. I don't get a wing "vibe" from this specimen, but that's just from what I can see in the photos, so take it with a grain of salt -- I may be wrong.

Thanks for the help.  The more I look at it the more I think it is plant.  The preservation of the plants in the nodules wasn’t great, so it would probably be unlikely for an insect to be preserved.
