Early Cretaceous dragonfly wing?

Here is a piece from the one of the Early Cretaceous formation in West Beijing.

I could not find any clues for ID.

I spliced the closeups .

Sorry. The pattern appears to be a cross section of a more dimensional shape.

I think it might be a wing

just found on internet  a pic of    Hemeroscopus baiscicus Pritykina,

my piece  looks close to the circled portion in the pic?

Very interesting. The outline is so detailed.
