The age of the earliest club mosses: the Silurian <i>Baragwanathia</i> flora in Victoria, Australia

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 &amp; Cookson and its associated flora persisted through the Přídolí and into the early Devonian, showing some changes during this time.
