ID of first plant impressions Coleraine Formation

[Irongiant97]

Plant impressions i found in material from the Coleraine formation of Northern Minnesota, which dates to 100-90mya, i confirmed with a paleontologist that these are first known plant impressions ever found up here which has me excited but neither of us know anymore than that theyre plant impressions, can anyone here maybe give more specific information from my pictures? 

i hope these pictures are good enough, i donated it for further study so I can’t get more. 
Even if you can’t ID them i still want to know what you guys think!

Not sure there is much there to identify - I see a lot of  impressions,  some look like leaves, some look like stems. They look like plants, but that is all I can really say. 

I think an actual paleobotanist familiar with the time period, may be required here.

I see what looks like a couple of Pecopteris sp. pinnules in one photo. I see lots of unidentifiable bits and pieces in all the others. These are definitely plant parts, though. Nice find.

Thanks! I didn’t think they’d be easy to identify, they aren’t the greatest fossils but finding any plant fossils here(besides wood) is extremely rare  so i can’t be picky.

My pictures aren’t great, irl they’re more…i can’t think of the word, but yeah. Hopefully i can make an update later on if the lab i donated to has anything on it.

Pecopteris died out in the Permian, and weren't around in the Cretaceous.

I understand, but the resemblance exists:

Cladophlebis sp. is a good possibility:
