Three new fossil bryophytes are described from Jurassic and Lower Cretaceous deposits of the Transbaikalia region of Russia. The complex thalloid hepatic Khasurtythallus monosolenioides gen. et sp. nov. belongs to the Marchantiidae, but its combination of characters precludes unequivocal placement in any of the five orders of this subclass, representing most likely an extinct lineage. Paleaethallus squarrosus gen. et sp. nov. is a thalloid plant with scales similar to those of complex thalloid… 

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.

A new phylogeny of the cladoxylopsid plexus: contribution of an early cladoxylopsid from the Lower Devonian (Emsian) of Quebec.

The sequence of character change recovered by the phylogenetic analysis supports a transition from actinostelic protosteles to dissected steles, associated with an increase in xylem rib number and medullation generating a central parenchymatous area.

Fossil mosses: What do they tell us about moss evolution?

The moss fossil records from the Paleozoic age to the Eocene epoch are reviewed and their putative relationships to extant moss groups discussed. The incomplete preservation and lack of key

The Khasurty Fossil Insect Lagerstätte

In terms of the composition of the fauna and flora, the Khasurty locality is very peculiar, it includes both Jurassic and Cretaceous taxa, but in general it can be attributed to the Jehol biota.

Recent Literature on Bryophytes — 123(1)

Three new moss species in the bryophyte flora of Montenegro and the key to the Campylopus complex (Leucobryaceae) in South American páramos are reported.

Early Land Plants Today: Index of Liverwort and Hornwort names published 2019–2020

A widely accessible authoritative list of known plant species is a fundamental requirement for local, regional, and global biodiversity conservation efforts. The longstanding index series of

This special issue celebrates the unique diversity of seed‐free land plants (SFLP) and in particular the contribution of Jochen Heinrichs (1969–2018), who dedicated his research to the study of the

The first discovery of mosses (Bryopsida) in the Lower Jurassic of Eastern Siberia

Most of the known diversity of Jurassic mosses comes from the Upper Jurassic of China, Mongolia, and Asiatic Russia. The Early Jurassic mosses are not known in Siberia. According to the study of



Exploring the fossil history of pleurocarpous mosses: Tricostaceae fam. nov. from the Cretaceous of Vancouver Island, Canada.

This new moss adds the first bryophyte component to an already diverse assemblage of vascular plants described from the Early Cretaceous at Apple Bay and, as the oldest representative of the Hypnanae, provides a hard minimum age for the group (136 Ma).

Extending the fossil record of Polytrichaceae: Early Cretaceous Meantoinea alophosioides gen. et sp. nov., permineralized gametophytes with gemma cups from Vancouver Island.

Meantoinea alophosioides enriches the documented moss diversity of an already-diverse Early Cretaceous plant fossil assemblage and represents the first occurrence of gemma cups in a fossil moss.

Hepatophytes from the Early Cretaceous of Alexander Island, Antarctica: Systematics and Paleoecology

The distribution of in situ liverworts, and a clear association of taxa with a variety of foliage types, indicated that the hepatophytes occupied a wide range of ecological niches during the Cretaceous.

Permian bryophytes of Western Gondwanaland from the Paraná Basin in Brazil

The discovery of such a fragile structure demonstrates that no prefossilization displacement took place and that the sediments accumulated in a low‐energy, fresh‐water environment, similar to a lake fed by rain, and isolated from the direct influence of the sea.

Grimmiaceae in the Early Cretaceous: Tricarinella crassiphylla gen. et sp. nov. and the value of anatomically preserved bryophytes

Discovery of Tricarinella re-emphasizes the importance of paleobotanical studies as the only approach allowing access to a significant segment of biodiversity, the extinct biodiversity, which is unattainable by other means of investigation.

Mosses from Rovno amber (Ukraine), 3. Pottiodicranum, a new moss genus from the Late Eocene

The Eocene moss fossil possesses a unique combination of characters and apparently belongs to an extinct group of Dicranidae, while the family relationships remain unclear.

Krassiloviella limbelloides gen. et sp. nov.: Additional Diversity in the Hypnanaean Moss Family Tricostaceae (Valanginian, Vancouver Island, British Columbia)

Krassiloviella limbelloides is the second bryophyte described as a result of ongoing studies of the Early Cretaceous Apple Bay flora of Vancouver Island and is also the second genus of family Tricostaceae, which provides the oldest unequivocal evidence for the pleurocarpous superorder Hypnanae and a hard minimum age for the group.

Sporophytes and Gametophytes of Polytrichaceae from the Campanian (Late Cretaceous) of Georgia, U. S. A.

These fossils, which represent the first unequivocal polytrichaceous sporophytes known from the fossil record, provide the first definitive evidence of modern families of mosses in the Cretaceous and demonstrate that mosses were already diverse by approximately 80 million years before present.

Bryophytic fossil remains in the Permian Gondwana formations are extremely rare. The rarity of fossil bryophytes is generally attributed to their delicate nature and small size of the plants. Fossil

Sporophytes and gametophytes of Dicranaceae from the Santonian (Late Cretaceous) of Georgia, USA.

Campylopodium allonense unequivocally provides the earliest evidence of Dicranaceae in the fossil record, and along with other fossil mosses from this late Santonian locality, indicates the presence of modern families of mosses in the Cretaceous.
