@richard-lee – have you played around in Macrostrat? It’s a cool digital geologic bedrock map: https://macrostrat.org/map/#/z=1.5/x=16/y=23/bedrock/lines/ you can move around to find what you are looking for.
They also have an option to search for strata: https://macrostrat.org/sift/#/strat_name_concept/9342
I think @mackenzie-smith was agreeing with your ID – I do too but am less familiar with fossil flora.
How big was your file? I think the size limit is 50 mb for fossil specimens but not sure about in forum posts.
