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.
Revision of the Mesozoic genus Mesotipula Handlirsch (Limoniidae, Diptera) from Asia extending its evolutionary history up to the Cretaceous
Abstract Genus Mesotipula (Limoniidae) has been recorded to date only from Jurassic localities. This paper presents results of investigation of the Asiatic species of the genus. New fossil finds from
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
The Khasurty locality (Lower Cretaceous of Transbaikalia, Russia) is one of the largest fossil insect sites in the region. Over the entire period of study, more than 6000 insect imprints have been

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
:  This study involves bryophyte fossils from the Teresina Formation (Permian–Guadalupian) collected in the Rio Preto Quarry in the state of Parana, southern Brazil. Two new genera are proposed, with
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.
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.
Phylogeny of haplolepideous mosses — challenges and perspectives
It is concluded that further phylogenetic analyses based on new combinations of markers are necessary at different taxonomic levels, especially to resolve the backbone of the Dicranidae phylogeny, but also to tackle large and taxonomically complex genera that are severely understudied.
