  author={Stephen McLoughlin and Christiane Pott and Ian H. Sobbe},
  journal={Palaeobiodiversity and Palaeoenvironments},
Several dispersed reproductive organs of bennettitopsid gymnosperms are described and illustrated from Triassic to Cretaceous strata of Australia: Williamsonia eskensis sp. nov. (Middle Triassic), Williamsonia ipsvicensis sp. nov. (Upper Triassic), Williamsonia durikaiensis sp. nov. (Lower Jurassic), Williamsonia sp. (Lower Jurassic), Williamsonia rugosa sp. nov. (Middle Jurassic), Williamsonia gracilis sp. nov. (Lower Cretaceous), Cycadolepis ferrugineus sp. nov. (Lower Jurassic), Cycadolepis… 

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

Palynology of Jurassic (Bathonian) sediments from Donbas, northeast Ukraine

A palynological and sedimentological study of an outcrop succession adjacent to the village of Kamyanka within the Kharkiv region of northeast Ukraine was carried out. The successions occur within

A hidden cradle of plant evolution in Permian tropical lowlands

Mixed plant-fossil assemblages from Permian equatorial lowlands in present-day Jordan are presented that harbor precocious records of three major seed-plant lineages that all became dominant during the Mesozoic, including the oldest representative of any living conifer family.

Early Cretaceous polar biotas of Victoria, southeastern Australia—an overview of research to date

All bennettitalean reproductive structures identified to date are dealt with and the systematic affinities of these taxa are discussed, as well as aspects related to their stratigraphy and palaeocology.

Williamsonia carolinensis sp. nov. and Associated Eoginkgoites Foliage from the Upper Triassic Pekin Formation, North Carolina: Implications for Early Evolution in the Williamsoniaceae (Bennettitales)

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.

Middle Triassic megafossil plants from Long Gully, near Otematata, north Otago, New Zealand

Abstract The Long Gully Formation of the Corbies Creek Group contains abundant remains of the low-diversity coastal vegetation characteristic of the Middle and Late Triassic Pacific margins of

Triassic species of Dictyophyllum from eastern Australia

Three species of dipteridacean ferns occur in the Triassic of eastern Australia: Dictyophyllum davidii Walkom 1917, D. bremerense Shirley 1898 and D. shirleyi (Herbst) comb. nov.; the descriptions of

Late Palaeozoic Foliage from China Displays Affinities to Cycadales Rather than to Bennettitales Necessitating a Re-Evaluation of the Palaeozoic Pterophyllum Species

The epidermal anatomy of Pseudoctenis samchokense is described revealing non-bennettitalean characters of these leaves from the Permo-Carboniferous of China (and Korea). The specimens were originally

Early Cretaceous mesofossils from Portugal and eastern North America related to the Bennettitales-Erdtmanithecales-Gnetales group.

Four new genera and six new species of fossil seed are described from five Early Cretaceous mesofossil floras from Portugal and eastern North America, suggesting that this newly recognized complex of extinct plants, together with Bennettitales, Erdtmanithecales, and Gnetales (the BEG group), is phylogenetically closely related.
