Caytonia nathorstii is an extinct species of seed ferns.

Caytonia has berry like cupules with numerous small seeds arrayed along axes

Different organs attributed to the same original plant can be reconstructed from co-occurrence at the same locality and from similarities in the stomatal apparatus and other anatomical peculiarities of fossilized cuticles.
