The exine ultrastructure of Williamsoniella coronata Thomas from the Bajocian of Yorkshire (United Kingdom) was investigated with light, scanning electron, and transmission electron microscopy. The pollen averages 16.5 μm along its short axis and 24.5 μm along its long axis and is monosulcate, and the nonapertural sculpturing is distinctly verrucate. The pollen wall is homogeneous, and the sulcus membrane is composed of thin exine with scattered small granules. The pollen grains differ in exine… 
The ultrastructure of fossil dispersed monosulcate pollen from the Early Cretaceous of Transbaikalia, Russia
Abstract The general morphology, surface sculpturing, and exine ultrastructure have been studied in dispersed monosulcate pollen from the Early Cretaceous of Transbaikalia, Russia. The pollen grains
The fine morphology of pollen grains from the pollen chamber of a supposed ginkgoalean seed from the Middle Jurassic of Uzbekistan (Angren locality)
Pollen grains of Cycadopites-type were found in the pollen chamber of a supposed ginkgoalean seed Allicospermum sp. from the Middle Jurassic deposits of Uzbekistan (Angren locality). The pollen
Ultrastructure and Probable Botanical Affinity of the Enigmatic Sporomorph Froelichsporites traversei from the Norian (Late Triassic) of North America
TLDR
Froelichsporites traversei is a prominent palynomorph in the Upper Triassic of North America that always occurs in tetrahedral permanent tetrads and represents most likely a gymnosperm.
A lyginopterid pollen organ from the upper Permian of the Dead Sea region
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
Lunzia austriaca – a bennettitalean microsporangiate structure with Cycadopites-like in situ pollen from the Carnian (Upper Triassic) of Lunz, Austria
TLDR
It is revealed that Lunzia austriaca is a pollen organ resembling structures assigned to Weltrichia, and its structure is compared with several contemporary bennettitaleans; sterile foliage and ovulate structures most likely associated with Lunziale are Pterophyllum filicoides and Westersheimia pramelreuthensis, respectively.
Williamsonia carolinensis sp. nov. and Associated Eoginkgoites Foliage from the Upper Triassic Pekin Formation, North Carolina: Implications for Early Evolution in the Williamsoniaceae (Bennettitales)
TLDR
The unique features of W. carolinensis, along with the probable affinity with Eoginkgoites foliage, expands the known diversity of the Williamsoniaceae and supports previous suggestions of remarkably high levels of morphological disparity in the earliest history of the Bennettitales.

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.
IN SITU GYMNOSPERM POLLEN FROM THE MIDDLE JURASSIC OF YORKSHIRE
TLDR
The morphology of pollen grains yielded by male Gymnosperm fructifications from the Jurassic flora of Yorkshire is studied and discussed and it is suggested that all members of the Hirmerella-group have an epidermis with a special type of stoma.
The ultrastructure of three monosulcate pollen grains from the triassic chinle formation, western United States
  • M. Zavada

TLDR
The occurrence of pre‐Cretaceous dispersed pollen from the Chinle Formation with convergent an‐giosperm characters suggests that these Triassic palymomorphs may have been functionally similar to some angiosperms.
Is the anthophyte hypothesis alive and well? New evidence from the reproductive structures of Bennettitales.
TLDR
Characters of bennettitalean plants are summarized and new evidence for the structure of cones and seeds is presented that help clarify relationships of Bennettitales to flowering plants, Gnetales, and other potential angiosperm sister groups.
Phase-contrast X-ray microtomography links Cretaceous seeds with Gnetales and Bennettitales
Over the past 25 years the discovery and study of Cretaceous plant mesofossils has yielded diverse and exquisitely preserved fossil flowers that have revolutionized our knowledge of early
Bennettitales from the Grisethorpe Bed (Middle Jurassic) at Cayton Bay, Yorkshire, UK.
TLDR
Bennettitales, a key group in discussions of how angiosperms may be related to other seed plants, are especially well represented among mesofossils from the Grisethorpe Bed and provide new information on these extinct plants.
