Hitherto the earliest record of a fossil flora containing Cooksonia type sporangia was from a mid-Ludlow (Silurian) locality in Wales1. The compression fossils illustrated here (Figs 1–4) come from strata assigned to the highest graptolite zone of the Wenlock Series characterized by Monograptus ludensis. They were collected (by J. F.) in the Devilsbit Mountain district of County Tipperary, Ireland. But this is not just a record of the first appearance of a genus which extends to the end of the… 

A late Wenlock flora from Co. Tipperary, Ireland

It is concluded that these plants provide the earliest record of erect fertile land plants of possible pteridophyte affinity and sedimentological and palaeontological studies of the region provide little direct evidence for the habitats of the plants which are considered to have been terrestrial.

Plant assemblages from the Silurian of southern Bolivia and their palaeogeographic significance

Their overall morphological grade is closer to material collected from circum-northern Atlantic localities than from assemblages in Australia and Kazakhsta/nChina, which translates into floristic similarities between Gondwanan high latitudes and equatorial Laurussia rather than with low latitude, north-eastern Gondwana or with a low latitude Kazakhstan/ Xinjiang micro-palaeocontinent.

Silurian fungal remains: probable records of the Class Ascomycetes

It is suggested that these microfossils obtained from the late Silurian Burgsvik Sandstone represent the remains of the imperfect stages of terrestrial Ascomycetes, and provide evidence for an origin of this group at least contemporaneous with the earliest land plants.

GRAPTOLITE BIOSTRATIGRAPHY OF EARLY LAND PLANTS FROM VICTORIA, AUSTRALIA

SUMMARY After a complete re-examination and reappraisal of all the plants and graptolites at the two critical localities of Limestone Road and Ghin Ghin, it is concluded that the overwhelming

An early origin of secondary growth: Franhueberia gerriennei gen. et sp. nov. from the Lower Devonian of Gaspé (Quebec, Canada).

Franhueberia is one of the three oldest euphyllophytes exhibiting secondary growth documented in the Early Devonian, and represents basal lineages that predate the evolution of stem-leaf-root organography and indicates that underlying mechanisms for secondary growth became part of the euphllophyte developmental toolkit very early in the clade's evolution.

Evolutionary Floras ‒ revealing large-scale patterns in Palaeozoic vegetation history

The overarching trajectory of Palaeozoic vegetation history can be interpreted as the sequential replacement of the Eotracheophytic, Eophytic, Palaeophytic and Mesophytic evolutionary floras. Each

The invasion of the land surface by plants, particularly vascular plants, occurred in Late Silurian and Early Devonian time, approximately 405 to 370 million years ago (Table 1). During more than a
