ABSTRACT Several new gametophytes are described from the Early Devonian Rhynie chert. The new monotypic genus Remyophyton, being the gametophyte of Rhynia, is represented by a dense stand of in situ preserved gametophytes with antheridia- and archegonia-bearing axes. The gametophytes are remarkably small in comparison to those of other Rhynie chert plants. The generic diagnoses of Lyonophyton and Langiophyton are emended to include archegonia- and antheridiabearing axes. All essential stages of… Expand
Filamentous green algae from the Early Devonian Rhynie chert
A relatively neglected element of the biota of the Lower Devonian Rhynie chert Lagerstätte are filamentous green algae exceptionally preserved by silicification. Palynological processing of sedimentsExpand
Reproductive Organs and In Situ Spores of Asteroxylon mackiei Kidston & Lang, the Most Complex Plant from the Lower Devonian Rhynie Chert
TLDR
Asteroxylon mackiei is the largest and most complex vascular land plant from the Lower Devonian Rhynie Chert and several fertile axes from longitudinal and transverse thin sections are document, suggesting a periodicity of growth. Expand

The Early Devonian Rhynie chert and the nearby Windyfield chert contain the oldest in situ preserved terrestrial ecosystem. Two of the seven species of anatomically preserved land plants had nakedExpand
Spores of the Rhynie chert plant Aglaophyton (Rhynia) major (Kidston and Lang) D.S. Edwards, 1986
Abstract Detailed studies have been undertaken on in situ spores of the Rhynie chert plant Aglaophyton (Rhynia) major (Kidston and Lang) D.S. Edwards. The in situ spores exhibit a variety ofExpand
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
Paleomycology of the Princeton Chert. III. Dictyosporic microfungi, Monodictysporites princetonensis gen. et sp. nov., associated with decayed rhizomes of an Eocene semi-aquatic fern
TLDR
The fungal body fossils described here occur in decayed rhizomes of the extinct semi-aquatic fern Dennstaedtiopsis aerenchymata, providing new insight into the rapidity of initial phases of the fossilization process in this important paleobotanical locality. Expand
Further observations on the spores of the Rhynie chert plant Horneophyton lignieri (Kidston & Lang) Barghoorn & Darrah, 1938: Implications for palaeodiversity studies
TLDR
These findings show that the sporangia of a same plant species may deliver diverse taxa of coeval isolated spores, and highlights that caution is needed when comparing plant diversity with the dispersed spore fossil record. Expand
Lower Devonian plant and spore assemblages from Lower Old Red Sandstone strata of Tredomen Quarry, South Wales
Abstract Tredomen Quarry, near Brecon, South Wales, is regarded as a Lower Old Red Sandstone terrestrial lagerstatten and has yielded a palaeobotanical assemblage that illustrates the diversity andExpand
Palaeolyngbya kerpii sp. nov., a large filamentous cyanobacterium with affinities to Oscillatoriaceae from the Lower Devonian Rhynie chert
TLDR
All specimens of P. kerpii occur in a small area of clear chert intercalated between substrate layers, and thus support the hypothesis that substrate served as a conservation trap for delicate microbial life in the Rhynie setting. Expand

The first zosterophyll from the Lower Devonian Rhynie Chert, Aberdeenshire
TLDR
Fragmentary remains of a vascular sporophyte from the Rhynie Chert are described as a new genus and species, Trichopherophyton teuchansii, which is assigned to the Zosterophyllophytina, but lack of information on the arrangement of sporangia prevents its more precise positioning within the subdivision. Expand
Evidence for the sporophytic status of the lower devonian plant rhynia gwynne-vaughanii kidston and Lang
TLDR
It is shown that Rhynia gwynne-vaughanii was far more branched than originally suggested and evidence has been obtained which suggests that sporangia develop an “abscission layer” at their base after the spores are shed; this may lead to the development and growth of branches arising immediately below the abscissions layer. Expand
Aglaophyton major, a non-vascular land-plant from the Devonian Rhynie Chert
TLDR
The genus Aglaophyton is described to accommodate the plant formerly known as Rhynia major, re-examined using new material and techniques and cannot be considered a member of either group; at the present time it is not assigned to a higher category. Expand
The Gametophyte Generation of Some Early Devonian Land Plants
TLDR
Their construction indicates some degree of morphological similarity between haploid and diploid thalli in the life cycles of these entities, thus supporting to some extent an alternation of isomorphic generations and the homologous theory of sporophyte origin for land plants. Expand
Devonian Gametophytes with Anatomically Preserved Gametangia
TLDR
The oldest anatomically preserved and physiologically apparently independent gametophytes are described from the Lower Devonian of Scotland, with upright, leafless axes with terminally borne, bowl-shaped game-tangiophores. Expand
Observations on Nothia aphylla Lyon ex Høeg
TLDR
Nothia aphylla is described here in greater detail from new material collected from the Rhynie locality and systematically Nothia has similarities to both Zosterophyllophytina and Rhyniophytinas. Expand
New information on gametophytes and sporophytes of Aglaophyton major and inferences about possible environmental adaptations
TLDR
Serial sections of aerial axes of gametophytes and sporophytes of Aglaophyton have yielded new histological and developmental features, including cuticle structures, stomatal and substomatal features, and a hitherto undescribed type of specialized cortical tissue, arrested apices, and bulbil-like organs are documented. Expand
Studies in the flora of the Rhynie chert
TLDR
This work is entirely concerned with the fossil flora of the Rhynie chert bed in Scotland and it is suggested that Nothin sphylla should be classified in the family Zosterophyllaceae. Expand

TLDR
Oxygen isotope and organic geochemical data from the Rhynie cherts indicate a temperature apparently greater than the temperature at which elements of the biota were preserved and represents subsequent shallow burial in the hot spring system. Expand
Germinating Spores in the Rhynie Chert
TLDR
A small loose block of Rhynie Chert has been found to contain a number of isolated spores which appear to have been germinating at the time when the onset of conditions favouring their preservation occurred, in some cases it is clear that development had only just commenced. Expand
