Abstract

It is argued that there is overwhelming evidence from a good graptolite record that the earliest club mosses on Earth were of Gorstian (Ludlow, Silurian) age, and that Baragwanathia longifolia Lang & Cookson and its associated flora persisted through the Prídolí and into the early Devonian, showing some changes during this time.
