Abstract. We describe Equisetum dimorphum sp. nov. from the Lower Jurassic of Chubut Province, Patagonia, Argentina. This new species Is based on fertile and vegetative remains preserved as Impressions of stems, leaves, strobili, transversal sections of the stems showing their anatomy, and terminal pagoda-like structures. The fine-grained sedimentary matrix also preserved detailed Impressions of epidermal features. The morphological characters allow a whole-plant reconstruction and assignment… Expand
Origin of Equisetum: Evolution of horsetails (Equisetales) within the major euphyllophyte clade Sphenopsida.
A combined approach to parsimony phylogenetic analyses to address relationships of 43 equisetalean species using a combination of morphological and molecular characters provides useful tests of hypotheses about overall phylogenetic relationships of euphyllophytes and foundations for future tests of molecular dates with paleontological data.

New fossil material of Equicalastrobus (Equisetales) and associated leaves from the Late Triassic of Baojishan basin, Gansu Province, China
ABSTRACT A new species of Equicalastrobus pusillus L. Zhang et D.F. Yan sp. nov. and associated leaves Schizoneura koningensis were reported from the Late Triassic of Baojishan basin, Gansu Province,Expand
Towards a whole plant reconstruction for Austrohamia (Cupressaceae): New fossil wood from the Lower Jurassic of Argentina
Permineralized woods from the same strata where Austrohamia minuta was found in the Canadon Asfalto Basin, Chubut Province, Argentina are described, and a new specific taxon for the Patagonian specimens is proposed. Expand
The unexpected, recent history of horsetails in Australia
This specimen provides the youngest evidence of the genus from Australia and indicates that Equisetum survived for at least another 50 million years after it was thought to be extinct in Australia. Expand
Fossil flora of Middle Jurassic Grojec clays (southern Poland). Raciborski’s original material reinvestigated and supplemented. I. Sphenophytes
Sphenopsid remains from Grojec clays collected and described by Raciborski in 1894 are re-examined for the first time and supplemented by RacIBorski’s unpublished material housed at the Jagiellonian University (Institute of Botany) and by Stur's preliminarily described material stored at the Geological Survey of Austria. Expand
Biogeography and genome size evolution of the oldest extant vascular plant genus, Equisetum (Equisetaceae).
The most extensive phylogenetic analysis to date is used as a framework to evaluate Horsetails' age, biogeography and genome size evolution, finding that differences in genome size between subgenera may be related to the number of sperm flagellae. Expand
Fossil flora of Middle Jurassic Grojec clays (southern Poland). Raciborski’s original material reinvestigated and supplemented. II. Pteridophyta. Osmundales
Abstract In the second part of the series dealing with the flora of the Grojec clays (Poland, Middle Jurassic), macroremains of Osmundales are introduced. The re-examined and supplemented materialExpand
Middle-Late Jurassic megaflora of Laguna Flecha Negra locality in Santa Cruz Province, Patagonia, and floristic assemblages of the Bahía Laura Complex
Abstract A Middle-Late Jurassic fossil plant assemblage is described from the Bahia Laura Complex at the Laguna Flecha Negra locality, Santa Cruz Province. The fossil assemblage is autochthonous,Expand
The first Cenozoic Equisetum from New Zealand
Abstract Equisetum is described for the first time from Cenozoic deposits of New Zealand. The fossils derive from two early to earliest middle Miocene assemblages in South Island, New Zealand. TheExpand
Origin of horsetails and the role of whole-genome duplication in plant macroevolution
Support for at least one WGD event shared among the majority of extant Equisetum species is confirmed and the need for a review of the proposed roles of WGDs in biological innovation and extinction survival in angiosperm and non-angiosperm lineages alike is precipitate. Expand


Equisetum thermale sp. nov. (Equisetales) from the Jurassic San Agustín hot spring deposit, Patagonia: anatomy, paleoecology, and inferred paleoecophysiology.
E. thermale supports the hypothesis of a Mesozoic origin for the crown group of Equisetum, because it is preserved in situ with intact anatomy and provides clear paleoecological, biological, plus inferred paleoECophysiological evidence of adaptations known in extant species. Expand
Phylogenetic diversification of Equisetum (Equisetales) as inferred from Lower Cretaceous species of British Columbia, Canada.
Three types of anatomically preserved vegetative shoots with features that characterize crown group Equisetum have been discovered in Lower Cretaceous deposits (≈136 Ma) of British Columbia, Canada,Expand
A new genus of the Cupressaceae (sensu lato) from the Jurassic of Patagonia: Implications for conifer megasporangiate cone homologies
This conifer possesses a combination of characters indicating placement within the basal Cupressaceae ( i.e. the former “Taxodiaceae”) and is supported by a phylogenetic analysis that places the Argentinean fossil close to the extant genera Athrotaxis and Cunninghamia and the fossil genera Elatides and Sewardiodendron. Expand
The Equisetalean Genus Cruciaetheca nov. from the Lower Permian of Patagonia, Argentina
The use of the genus Phyllotheca is reevaluate in light of finding Phylletheca foliar whorls associated with completely distinct reproductive characters, as well as the significance of its cruciate sporangiophores and other characters. Expand
Phylogenetic Relationships and Evolution of Extant Horsetails, Equisetum, Based on Chloroplast DNA Sequence Data (rbcL and trnL‐F)
The Equisetum crown group appears to have diversified in the early Cenozoic, whereas theEquisetaceae total group is estimated to have a Paleozoic origin, in remarkable agreement with current interpretations of the fossil record. Expand
A new marattiaceous fern from the Lower Jurassic of Patagonia (Argentina): the renaissance of Marattiopsis
It appears that essentially modern marattioid ferns, including Marattiopsis, which are commonly considered to be typical elements of tropical areas of the northern hemisphere during the Mesozoic, may have left an important but largely ignored fossil record in subtropical Gondwana. Expand
Phylogeny of Horsetails (Equisetum) based on the Chloroplast rps4 Gene and Adjacent Noncoding Sequences
On the basis of the present phylogeny, bisexuality would not be the ancestral state in the Equisetum genus, but characters shared among species of the subgenus Equisettum, such as superficial stomata and protruding antheridia, could be ancestral in the genus. Expand
A new equisetalean plant from the early Permian of Patagonia, Argentina
The sphenophyte Peltotheca furcata, nov. gen. et sp., is described based on vegetative and reproductive organs. Unbranched vegetative axes bear foliar whorls of Barakaria-type leaves, whileExpand
A reappraisal of Neocalamites and Schizoneura (fossil Equisetales) based on material from the Triassic of East Antarctica
Sphenophytes are a common floral element in the Triassic of Gondwana. Most sphenophyte compression fossils have been conventionally assigned to a few, presumably very widespread species ofExpand
Morphology of Equisetum laterale Phillips, 1829, and E. bryanii sp. nov. from the Mesozoic of South-Eastern Queensland
