Another four more Mazon Creek for ID

[Mark Kmiecik]

And another four that I need help with. Thank you in advance.

E0021 - Pecopteris? Other?

E0040 - Mariopteris? Neuropteris? Best guess? Venation not clearly visible.

E0098 - Cyclopteris obicularis? This one I'm fairly sure of.

I0002 - Paleocaris typus? Acanthotelson? Other?

Still need some help with these.

I would be grateful for your assistance with confirmation, ID, or even a guess at what these are. Thank you.

@Mark Kmiecik Could you get a clearer picture of, or describe, the venation of E0021? It looks like the lateral veins are forking near the base and that's it, but it's hard to tell from the current picture.

[Mark Kmiecik]

@connorp   Easier to see in the negative view. Veins fork once only, near the midvein of the pinnule. Venation is sparse with no intermediate non-forking veins.

Now look what you made me do! This is going to be very time-consuming.

Very nice! I'd probably lean towards Pecopteris oreopteridia.

I think you have E0021 sorted.  E0098 is an orbicular pinnule from a Macroneuropteris scheuchzeri.  I0002 is a Paleocaris typus.  The tail gives it away.  https://www.esconi.org/esconi_earth_science_club/2021/06/mazon-monday-65-species-spotlight-paleocaris-typus-fossil-mazoncreek-mazonmonday-paleontology-shrimp.html

Thank you @stats. I was waiting for someone else to notice the telson on I0002.
