Structurally preserved fossil ferns are extremely significant for exploring the origin and evolution of this plant clade; however, they are quite scarce and limited in the Mesozoic. Here, we report some well-preserved fern rhizomes and rachides with anatomical details from the Upper Jurassic Manketouebo Formation in Inner Mongolia, NE China. Two taxa, including Ashicaulis liaoningensis (Zhang et Zheng) Tidwell referred to Osmundaceae and Gleicheniorachis sinensis sp. nov. referred to…

Plenasium xiei sp. nov. from the Cretaceous of Northeast China: Additional evidence for the longevity of osmundaceous ferns
A new species of the Osmundaceae, Plenasium xiei sp. nov., is herein described from the Cretaceous of Northeast China. The specimens examined here represent the earliest unequivocal record of the
Two new species of Mesozoic tree ferns (Osmundaceae: Osmundacaulis) in Eurasia as evidence of long-term geographic isolation
The fossil records suggest that Osmundacaulis species may have evolved from a common ancestor, which first appeared in the Australian portion of Pangaea, and then spread to ancient northern North America and ancient East Asia.
A permineralized thamnopteroid rhizome (Osmundaceae) with coprolites from the Permian of Heilongjiang Province, Northeast China: The most primitive record of Osmundaceae in Asia
Abstract The earliest and most primitive fossil trunk or rhizome taxa of the family Osmundaceae, as important evidence for understanding its early evolutionary history, have so far all come from the

A new structurally preserved fern rhizome of Osmundaceae (Filicales) Ashicaulis wangii sp. nov. from the Jurassic of western Liaoning and its significances for palaeobiogeography and evolution
Osmundaceous rhizome fossils from China show endemic anatomical characteristics and significances for palaeobiogeography, and Comparisons of anatomical features suggest that A. wangii sp.
A new structurally preserved fern rhizome of Osmundaceae (Filicales) Ashicaulis wangii sp. nov. from the Jurassic of western Liaoning and its significances for palaeobiogeography and evolution
Permineralized osmundaceous rhizome with anatomical and phylogenetic information plays a significant role in understanding the origin, evolution, and diversity variation of the fern family
Ashicaulis beipiaoensis sp. nov., a New Osmundaceous Fern Species from the Middle Jurassic of Liaoning Province, Northeastern China
A new structurally preserved fern rhizome species, Ashicaulis beipiaoensis (Osmundaceae), is described from the Middle Jurassic Tiaojishan Formation in Beipiao City, Liaoning Province, northeastern
A new species of osmundaceous fern rhizome, Ashicaulis macromedullosus sp. nov., from the Middle Jurassic, northern China
This is the third structurally preserved rhizome of Ashicaulis from the Mesozoic in northern China and adds to the knowledge of fern diversity in China.
A specialized new species of Ashicaulis (Osmundaceae, Filicales) from the Jurassic of Liaoning, NE China
Recognition of the peculiar structure of this new fossil species enriches anatomical diversity of permineralized osmundaceous ferns, indicating that the family Osmundaceae might have experienced a remarkable diversification during the Middle Jurassic in NE China.
Gleichenia appianensis sp. nov. (Gleicheniaceae): A Permineralized Rhizome and Associated Vegetative Remains from the Eocene of Vancouver Island, British Columbia
A permineralized gleicheniaceous rhizome with an attached stipe base has been identified from the Appian Way locality on Vancouver Island, British Columbia, Canada, and represents the first record of Gleicheniaceae in the Tertiary of North America.
A new species of Ashicaulis (Osmundaceae) from the Mesozoic of China: A close relative of living Osmunda claystoniana L.
A new species is established based on two specimens collected from Middle Jurassic sediments near Duanmugou, Changgao Village, Beipiao County, west Liaoning Province of China, suggesting that the morphogenera Millerocaulis and Ashicaulis are closely related, and the new species may be a transitional form between the Mesozoic M. preosmunda and Osmunda claytoniana.
A New Species of Millerocaulis (Osmundaceae) from the Middle Jurassic of China and Its Implication for Evolution of Osmunda
A new species, Millerocaulis preosmunda, is established based on specimens collected from the Lanqi Formation (Middle Jurassic) near Changgao, Liaoning Province, China, and provides evidence for
