I once saw a suggestion that, in addition to ferns, quillworts
(Isoetes and relatives) made up a large part of the ground cover
before sedges and grasses.
At first I was skeptical, as quillworts rely upon water for pollination.
However, it apparently doesn't take much, as I recently discovered that
they live in some unlikely places still (like alpine meadows).
The peace of God be with you.
