UNLABELLED • PREMISE OF THE STUDY Understanding fern (monilophyte) phylogeny and its evolutionary timescale is critical for broad investigations of the evolution of land plants, and for providing the point of comparison necessary for studying the evolution of the fern sister group, seed plants. Molecular phylogenetic investigations have revolutionized our understanding of fern phylogeny, howe...

Background Ferns, originated about 360 million years ago, are the sister group of seed plants. Despite the remarkable progress in our understanding of fern phylogeny, with conflicting molecular evidence and different morphological interpretations, relationships among major fern lineages remain controversial. Results With the aim to obtain a robust fern phylogeny, we carried out a large-scale ...

Two excellently preserved small strobili were obtained from a Wealden plant debris bed in the Lower Cretaceous (Barremian) Wessex Formation, south-east of Chilton Chine, on Isle Wight, southern England. The are as compressions and show characteristic morphology sporangiophore heads Equisetales. Based strobili, attribution to certain species is not warranted. Therefore, have been left unassigned...

Jurassic deposits are discovered in the Shahreza area, southwest of Isfahan city, central Iran. They yield plant macrofossils belonging to 22 species assigned to 17 genera of various orders such as Equisetales, Filicales, Bennettitales, Cycadales, Ginkgoales and Coniferales. According to the occurrence of Annulariopsis simpsonii, Coniopteris hymenophylloides, Cladophlebis aktashensis, Nilssonia...
