  author={Ruiyun Li and Xuelian Wang and Jingwei Chen and Sheng-hui Deng and Zixi Wang and Junling Dong and Bainian Sun},
Here we described a fossil thalloid liverwort from the Middle Jurassic Xishanyao Formation, Turpan–Hami Basin, China, preserved as a carbonized compression in greyish-green siltstones. The fossil thalloid liverwort is characterized by the long and strap-like thallus with a well-defined costa, entire margins and polygonal cells in the thallus wings. Following comparisons of the present fossil with extant and other related fossil liverworts, a new species, Pallaviciniitessandaolingensis sp. nov… 

Ricciopsis sandaolingensis sp. nov., a new fossil bryophyte from the Middle Jurassic Xishanyao Formation in the Turpan-Hami Basin, Xinjiang, Northwest China

The liverwort family Ricciaceae has a very sparse fossil record in contrast to its large number of living species and its wide distribution. Fossil thalli collected from the Middle Jurassic Xishanyao

New Fossil Liverworts from the Lower Cretaceous of Western Liaoning, China

Sixteen liverwort specimens collected from the Lower Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, China are studied in this work. The plants are thalloid and preserved in

Two new species of Nilssoniopteris (Bennettitales) from the Middle Jurassic of Sandaoling, Turpan-Hami Basin, Xinjiang, NW China

The stratigraphic and geographical distributions of all 45 Jurassic Nilssoniopteris species worldwide have been summarized and analyzed to better understand their brief evolutionary history, indicating that Nilssoniaopteris might be able to grow not only in subtropical regions as the living cycads are, but also in warm climatic regions.

A New Species of Ginkgo with Male Cones and Pollen Grains in situ from the Middle Jurassic of Eastern Xinjiang, China

Well‐preserved Ginkgo pollen organs are analyzed from the Middle Jurassic Xishanyao Formation of the Turpan–Hami Basin, Xinjiang Uygur Autonomous Region, northwestern China, and are described as a

Defying death: incorporating fossils into the phylogeny of the complex thalloid liverworts (Marchantiidae, Marchantiophyta) confirms high order clades but reveals discrepancies in family‐level relationships

A total‐evidence analysis of Marchantiidae incorporating fossils challenges the widespread notion that bryophyte fossils are problematic for phylogenetic inference.

Ordovician land plants have long been suspected from indirect evidence of fossil spores, plant fragments, carbon isotopic studies, and paleosols, but now can be visualized from plant compressions in



Illuminating the evolutionary history of liverworts (Marchantiophyta)—towards a natural classification

The Jungermanniales are most probably a recently diversified group which has attained the greatest profusion of structure and the most remarkable diversity of leaf development and protective devices for maturing sporophytes.

Towards a natural classification of liverworts (Marchantiophyta) based on the chloroplast gene rbcL

The results indicate a subdivision of Marchantiophyta into three well sup- ported classes assigned as Haplomitriopsida, Marchantiopsida and Jungermanniopsida which may represent the oldest extant lineage of land plants.


Leptostrobus has been only reported in northeastern Sichuan, northern Qinghai and western Liaoning of China,which was with insufficient information. In this paper, the author reports the new

Phylogeny and taxonomy of the complex thalloid liverwort family Cleveaceae cavers

The study presents the first robust phylogenetic framework for the family, based on three chloroplast genes and one nuclear ribosomal region sequenced for 54 ingroup accessions representing a substantial part of the geographic range of the family and a large part of its morphological diversity.

Morphology and classification of the Marchantiophyta

This work states that liverworts are a heteromorphic life cycle in which the sporophyte is comparatively shortlived and nutritionally dependent on the free-living gametophyte, but differ from both in numerous anatomical features as detailed by Crandall-Stotler (1984).

Progress towards a robust phylogeny for the liverworts, with particular focus on the simple thalloids (Selected Papers Presented at the 15 World Congress on Bryology Held at Merida, Venezuela, January 12-16, 2004)

An eight locus analysis using sequences from the chloroplast rbeL, rps4, psbA, alp8 and trnLuAA regions for 64 liverworts, nine mosses and five hornworts resolves five well supported lineages within the Marchantiophyta.

A New Species of Sphenobaiera from Middle Jurassic of Junggar Basin,Xinjiang,China

A new species Sphenobaiera junggarensis sp. nov. from the Middle Jurassic Xishanyao Formation in western Junggar Basin of Xinjiang, China, is reported for the first time. The new species is
