Several recent palaeobotanical studies claim to have found and described pre-Cretaceous
angiosperm macrofossils. With rare exceptions, these papers fail to define a flower, do not …

Abstract The Toploje Member chert is a Roadian to Wordian autochthonous–
parautochthonous silicified peat preserved within the Lambert Graben, East Antarctica. It …

We review the diversity and development of archegonia, the female reproductive organs of
land-plant gametophytes. The archegonium is a uniquely land-plant structure, and studies of …

Background Guangdedendron micrum is the Late Devonian tree lycopsid that made up
Xinhang fossil forest in Anhui, China, showing the earliest stigmarian rooting system. Based …

Abstract Paralycopodites Morey & Morey, a Carboniferous‐age arboreous lycopsid that
grew in the tropical wetlands of Pangea, is the phylogenetically basalmost member of the …

Diminutive, silica-permineralized lycopsid axes, from a Guadalupian (Middle Permian)
silicified peat in the Bainmedart Coal Measures of East Antarctica are described and …

A unique Guadalupian (mid-Permian) megaspore assemblage has been recovered from
permineralised peats capping a coal seam in the Bainmedart Coal Measures, Prince …

In Scotland, the base of the Ballagan Formation has traditionally been placed at the first grey
mudstone within a contiguous Late Devonian to Carboniferous succession. This convention …

A new genus of bisporangiate sigillarian strobili Bisigillariostrobus with the only species
Bisigillariostrobus prolificus is proposed. A large number of strobili originates from the Wuda …
