Abstract Here we report a pollen organ from the upper Permian of the Dead Sea region with in situ pollen showing a wall structure typical for lyginopterid seed ferns. The single specimen resembles the dispersed seed-fern pollen organs Dictyothalamus and Melissiotheca in being composed of numerous densely positioned, radiating pollen sacs that together form a characteristic honeycomb-like surface pattern. The small, rounded to oval, non-saccate cryptaperturate in situ pollen grains have a…

Bennettitalean Leaves From the Permian of Equatorial Pangea—The Early Radiation of an Iconic Mesozoic Gymnosperm Group
Bennettitaleans are an extinct group of gymnosperms that are among the most iconic plants of Earth’s vegetation during the Mesozoic Era. The sudden appearance and rise to dominance of the
ATLAS OF SELECTED KINNEY QUARRY PLANT FOSSILS, LATE PENNSYLVANIAN, CENTRAL NEW MEXICO
During the Late Pennsylvanian, seasonality and rainfall increased in western Pangea, which led to the expansion of “mixed” floras composed of a combination of wetland and drought-tolerant plants. One

In this paper we report the first occurrence of permineralized plant fossils in volcaniclastic lithologies from China and in doing so describe a new species of cardiocarpalean ovule permineralized
POLLEN MORPHOLOGY AND ULTRASTRUCTURE OF THE BENNETTITALES: IN SITU POLLEN OF CYCADEOIDEA'
TLDR
Pollen morphology and ultrastructure are compared with those of the bennettitalean genus Leguminanthus and the dispersed genus Monosulcites, and the fine structure of Cycadeoidea pollen is compared to that of the gymnosperm groups with which the Bennettitales are regarded to be most closely related.

TLDR
Studies of b Bennettitalean reproductive organs from Scania (Sweden), Jameson Land (Greenland), and Yorkshire (United Kingdom) facilitated reevaluation of the disputed architecture of bennettitalan seeds, and the findings clearly indicate that early bennett italean seeds can be interpreted as unitegmic.
The Pollen Ultrastructure of Williamsoniella coronata Thomas (Bennettitales) from the Bajocian of Yorkshire
TLDR
The exine ultrastructure of Williamsoniella coronata Thomas from the Bajocian of Yorkshire (United Kingdom) was investigated with light, scanning electron, and transmission electron microscopy, supporting the bennettitalean affinity of these dispersed pollen grains.
A Revision of the Pennsylvanian‐Aged Eremopteris‐Bearing Seed Plant
TLDR
Inclusion of the reconstruction of E. artemisiaefolia in a cladistic analysis of lignophytes suggests that it represents a distinct clade within a paraphyletic complex of basal pteridosperms and that it diverges after hydrasperman and medullosalean taxa and before the Callistophytales.
Anatomically Preserved Pteridosperm Stems and Rachises from Permian Floras of China
TLDR
Extending the geographical and stratigraphical ranges of these pteridosperm taxa means that each should now be considered as potentially important to seed plant evolution and phylogeny during the Permian as well as the Carboniferous.
