I know figuring out the IDs of bug wings can be very difficult, but if anyone on here can help I'd greatly appreciate it! I've found these and some others (that I put somewhere I would definitely remember) near Humboldt, Nebraska in the Indian Cave sandstone member of the Towne Formation which puts their age late Pennsylvanian to early Permian. To be completely honest I've wondered if a couple of them might actually be leaf impressions, but I'll let y'all help me figure that out.
