- relatively large pinnules, which are parallel-sided and often
somewhat contracted at the base - the pinnules are standing
obliquely upward and close together (often touching each other)
- they have a round apex and are often somewhat convex - the
midvein is firm and sunken - the lateral veins are forked close
to the midvein and afterwards again By far the most of the
Pecopteris fossils belong to this species. Rather large leaves
(up to 30 cm) occur. Width of the photo 5 cm.
