Review questions attribution of Devonian taxa to ferns while treating Lower Carboniferous filicalean evidence as substantially firmer.
Claim ledger
fossil-range · lowFilicopsida has no supported scalar range here: the historical class concept is not aligned with a single crown or total group, and the review questions Devonian fern assignments while recognizing firmer Lower Carboniferous filicalean evidence; the former 360–0 Ma display is withheld.
