definately leaves. wings from this time period have very pronounced veination. it is similar to macroneuropteris, but not exactly. i will see if i can find a better id for you.

well, i am still not certain, i would need a better pictures that shows the veins. here is what William Tidwell says in "common fossil plants of western north america"

Neuropteris,

Neuropteris pinnules were produced by medullosan seed ferns. they have a single-point attachment to the rachis and the midvein extends about 3/4th the distance to the apex. leteral veination is open and arises acutely from the midvien. the lateral veins strike the margin obliquely or at right angles. linopteris is a similar genus but exhibits net veination.

this is the closest thing that i can find. there is also anothe genus Mixoneura, which is similar but is only known from utah as far as i can tell.

hope this helps.
