A complete reconstruction of Caytonia nathorstii plant Retallack and Dilcher 1988
Description[]
Caytonia has berry like cupules with numerous small seeds arrayed along axes
Whole plant reconstructions[]
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.
- Caytonia nathorstii may have been produced by the same plant as (pollen organs) and Sagenopteris phillipsii (leaves).
