ehh, modern biology doesn't construct evolutionary history from fossil records, but from genetic similarities.

It's impossible to compare genetics from fossils and we can't study ancient long dead species besides fossil records for the most part.

yeah that's not what i meant. phylogenetic trees are constructed by considering the genetics of recent (living) species, not from fossils.

And this post is about ancestors of ferns which are unknown so I'm not sure what are you suggesting
