The origin and early evolution of plants on land
The origin and early evolution of land plants in the mid-Palaeozoic era, between about 480 and 360 million years ago, was an important event in the history of life, with far-reaching consequences forExpand

The timescale of early land plant evolution
Significance Establishing the timescale of early land plant evolution is essential to testing hypotheses on the coevolution of land plants and Earth’s System. Here, we establish a timescale for earlyExpand

EARLY EVOLUTION OF LAND PLANTS: Phylogeny, Physiology, and Ecology of the Primary Terrestrial Radiation
▪ Abstract The Siluro-Devonian primary radiation of land biotas is the terrestrial equivalent of the much-debated Cambrian “explosion” of marine faunas. Both show the hallmarks of novelty radiationsExpand

Water-Conducting Cells in Early Fossil Land Plants: Implications for the Early Evolution of Tracheophytes
Wall structure in the water-conducting cells of Rhynia gwynne-vaughanii and Asteroxylon mackiei from the Lower Devonian Rhynie Chert was examined and compared using thin sections and scanningExpand

A timeline for terrestrialization: consequences for the carbon cycle in the Palaeozoic
The geochemical carbon cycle is strongly influenced by life on land, principally through the effects of carbon sequestration and the weathering of calcium and magnesium silicates in surface rocks andExpand

Evolution of Lycopodiaceae (Lycopsida): estimating divergence times from rbcL gene sequences by use of nonparametric rate smoothing.
By use of nonparametric rate smoothing and nucleotide sequences of the rbcL gene, divergence times in Lycopodiaceae are estimated. The results show that much extant species diversity in LycopodiaceaeExpand

Phylogenetic relationships in Selaginellaceae based on RBCL sequences.
A phylogenetic framework is developed for the clubmoss family Selaginellaceae based on maximum parsimony analyses of molecular data. The chloroplast gene rbcL was sequenced for 62 species, whichExpand

Cryptospores and cryptophytes reveal hidden diversity in early land floras.
Cryptospores, recovered from Ordovician through Devonian rocks, differ from trilete spores in possessing distinctive configurations (i.e. hilate monads, dyads, and permanent tetrads). TheirExpand
