Material from the Rhaetian of Tasmania
referred to Thinnfeldia pinnata Walkom is described.
The leaf is of thick substance, once
pinnate, and probably abscissed. It shows a
moderately thick cuticle with most stomata on the
lower leaf surface, papil1ae over the stomatal pit,
an unmodified leaf margin, and irregular subsidiary
cells. With this information the leaf fits better
in Pachypteris Brongniart than Thinnjeldia
Ettingshausen, and is transferred to Pachypteris.
It is readily distinguishable from other adequately
known species of the genus.
