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
Morphology and microstructure of Pellites hamiensis nov. sp., a Middle Jurassic liverwort from northwestern China and its evolutionary significance
TLDR
Pelliales is a basal lineage of the simple thalloid liverworts and its occurrence in the Middle Jurassic Xishanyao Formation of the Turpan–Hami Basin suggests that the divergence time of the Pelliaceae is not later than the Middleassic.

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

Marchantites huolinhensis sp. nov. (Marchantiales) - A new fossil liverwort with gemma cups from the Lower Cretaceous of Inner Mongolia, China
TLDR
The fossil liverwort species Marchantites huolinhensis, along with other fossil records from other localities and age, indicates that the Marchantiales was already diverse in the Early Cretaceous and its morphological evolution is very slow.
Riccardiothallus devonicus gen. et sp. nov., the earliest simple thalloid liverwort from the Lower Devonian of Yunnan, China
TLDR
The age of Riccardiothallus devonicus suggests that the differentiation of Jungermanniopsida and Metzgeriidae was in the Early Devonian, significantly earlier than the assumptions derived from analyses of chloroplast DNA sequences of modern liverworts and current total evidence phylogenies.
Earth's oldest liverworts—Metzgeriothallus sharonae sp. nov. from the Middle Devonian (Givetian) of eastern New York, USA
Abstract Liverworts are generally regarded as rare elements in Palaeozoic floral assemblages. However, a focus on dark gray to black shales and siltstones in the Middle–Late Devonian Catskill Delta
Illuminating the evolutionary history of liverworts (Marchantiophyta)—towards a natural classification
TLDR
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
TLDR
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.

Phylogeny and taxonomy of the complex thalloid liverwort family Cleveaceae cavers
TLDR
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
TLDR
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)
TLDR
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.
