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… Expand

A late Wenlock flora from Co. Tipperary, Ireland
TLDR
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.

An Early Devonian flora, including Cooksonia, from the Paraná Basin (Brazil)
We report here the presence of an extensive flora from an early Lochkovian (Lower Devonian: ∼406 million years) locality in the Parana Basin (Brazil). The exceptional macrofossil assemblage includes… Expand
Plant assemblages from the Silurian of southern Bolivia and their palaeogeographic significance
TLDR
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.

New observations of the early land plant Eocooksonia Doweld from the Pridoli (Upper Silurian) of Xinjiang, China
Abstract As an early land plant previously reported from the Upper Silurian (Pridoli) of Xinjiang, Northwest China and Central Kazakhstan, the circumscription of Eocooksonia sphaerica (Senkevitsch)… Expand
An exceptional specimen of the early land plant Cooksonia paranensis, and a hypothesis on the life cycle of the earliest eutracheophytes
TLDR
This fossil is evidence that reduced thalloid gametophytes and branched axial sporophytes are plesiomorphic among the earliest eutracheophytes, and it is suggested that a major difference in life cycle defines a basal dichotomy in tracheophyte. Expand
Silurian fungal remains: probable records of the Class Ascomycetes
TLDR
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. Expand
Late Silurian plant microfossil assemblage from Guangyuan, Sichuan, China
Abstract A dispersed plant microfossil assemblage is described from Late Silurian deposits from Guangyuan, Sichuan, China. These strata are interpreted as nearshore, shallow marine deposits, and… Expand
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… Expand
An early origin of secondary growth: Franhueberia gerriennei gen. et sp. nov. from the Lower Devonian of Gaspé (Quebec, Canada).
TLDR
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. Expand
First record of Early Devonian (Lochkovian) flora from the Santa Rosa Formation - Alarache, Southern Bolivia
TLDR
The abundance of fragmented stems of varied size and parallel to bedding planes, along with the isolated sporangia in the plant assemblage suggests a short distance transportation under low energy conditions, probably from marginal palaeoenvironments to low energy marine settings. Expand

The oldest vascular land plants: A note of caution
TLDR
The oldest fossil proven to be a vascular land plant is Cooksonia, from the Pridolian Stage of the Silurian Period in Wales, and it is pointed out that these microfossils may originate from algae, bryophytes, or groups now extinct or from animals. Expand
