The paleobiogeography of the extant leptosporangiate fern families present in the Mesozoic is reviewed based mainly on data from megafossils that possess enough characters to be assigned to a family. Times of first appearances are discussed for each family, followed by their distribution throughout the Mesozoic. Paleolatitudes and climatic conditions indicate that first appearances of many fern families occur about or above 30° and in conditions of higher moisture. Much of fern distribution in… 
First megafossil evidence of Cyatheaceous tree fern from the Indian Cenozoic
A part of the compressed tree fern axis with leaf and adventitious root scars in unusual arrangement from Plio–Pleistocene sediments of Arunachal Pradesh, India is described as Cyathea siwalika sp.
Fossil evidence of eupolypod ferns in the mid-Cretaceous of Myanmar
TLDR
H. burmensis represents the first unequivocal fossil of a representative of the eupolypods from the middle Cretaceous and Reconstruction of ancestral character states suggests affinities of Holttumopteris to the Thelypteridaceae; however, several taxonomically relevant characters are not preserved.
Davallia (Polypodiales: Davalliaceae) macrofossils from Early Miocene Otago (New Zealand) with in situ spores
Abstract Fossil fern fronds referable to the extant fern genus Davallia (Polypodiales: Davalliaceae) bearing sporangia with in situ spores are described from the Early Miocene Foulden Maar diatomite
Monotypic colonies of Clathropteris meniscioides (Dipteridaceae) from the Early Jurassic of central Patagonia, Argentina: implications for taxonomy and palaeoecology
TLDR
A collection of over 130 specimens of the fossil dipterid fern Clathropteris meniscioides (Brongn. 1825) from in-situ colonies in the Lower Jurassic of Chubut, Argentina, provides evidence for the presence of dipterids in the Jurassic.
Cainozoic ferns and their distribution
The phytogeographic distribution of Cainozoic ferns is reported based upon a critical re-appraisal of the macrofossil and mesofossil record also taking account of evidence from a few highly
Fertile Osmundaceae from the Early Jurassic of Patagonia, Argentina
TLDR
It is demonstrated that two main osmundaceous reproductive morphologies; i.e., differentiated reduced or unreduced fertile laminae were already present and widespread in Gondwana by this time, and suggested that fossil representatives are better placed in morphotaxa than in any current genus.
A new fossil record of Thyrsopteridaceae (Cyatheales) from the mid-Cretaceous amber of Myanmar
Abstract Paleopalynology evidence and megafossil records indicated that tree fern order Cyatheales, played an important role in Mesozoic terrestrial ecosystem. Few fossil records of the family
Assessing the evolutionary history of the fern family Dipteridaceae (Gleicheniales) by incorporating both extant and extinct members in a combined phylogenetic study.
TLDR
Dipteridaceae was found to be monophyletic and characterized by highly anastomosing minor veins forming a meshwork of areoles with free-included veinlets.
Burmese amber fossils bridge the gap in the Cretaceous record of polypod ferns
TLDR
It is shown that diverse polypod ferns existed in the mid-Cretaceous woodlands of Myanmar, and integration of the new fossil evidence in a phylogenetic framework provides support to the hypothesis of a Cretaceous diversification of poly Podiales.
Simultaneous diversification of Polypodiales and angiosperms in the Mesozoic

TLDR
The estimated divergence patterns of Polypodiales and angiosperms converge to a scenario in which their main lineages were established simultaneously shortly before the onset of the Cretaceous Terrestrial Revolution, and further suggest a pre‐Cretaceous hidden history for both lineages.

REASSIGNMENT OF ASPIDIUM HETEROPHYLLUM TO A NEW GENUS IN THE FAMILY M ATONI ACE AE
TLDR
A fossil fern described originally by W. Fontaine as Aspidium heterophyllum has been reexamined and a new genus (Delosorus) is proposed; thus, the number of plants within the Lower Cretaceous Potomac Group that belong in the Matoniaceae is increased.
Paleoazolla, a new heterosporous fern from the Upper Cretaceous of Argentina.
TLDR
A comparison with other azollaceous and salviniaceous genera, particularly Azolla, is provided, together with a discussion of some evolutionary trends within the family.
The occurrence of the fern Hausmannia Dunker (Dipteridaceae) in the Cretaceous of Alexander Island, Antarctica
Hausmannia papilio Feruglio is a widespread component of Albian fossil floras on Alexander Island, Antarctic Peninsula. Hausmannia cannot be separated from extant Dipteris and is best regarded as a

TLDR
It appears that species differentiation of the tree ferns in the late Cretaceous age of Hokkaido was rather high, as it is now in tropical and subtropical regions.
The lower cretaceous ferns in the genus Anemia (Schizaeceae), Potomac group of Virginia, and relationships within the genus
TLDR
Based on characters of the fertile fronds, two species of fossil ferns from the Lower Cretaceous Potomac Group of the U.S.A., originally described as species of Osmunda by Fontaine in 1889, are transferred to the genus Anemia, suggesting possible phylogenetic arrangements and delimination of three taxonomic units within Anemia.
Eogonocormus—A new early cretaceous fern of Hymenophyllaceae from China
TLDR
A new Early Cretaceous fern of Hymenophyllaceae from north-eastern China is described based upon the type species Eogonocormus cretaceum sp.
Reexamination of the fossil fern genus Dryopterites Berry based on reproductive characteristics
TLDR
Details of the reproductive characters including the spores are described for the first time and comparisons with Sporae Dispersae suggest a later Cretaceous occurrence of ferns related to the modern dryopterids.
A NEW SPECIES OF MARSILEA FROM THE DAKOTA FORMATION IN CENTRAL KANSAS
TLDR
A new fossil species from the Cenomanian of Kansas extends the megafossil record of the genus Marsilea back to the mid-Cretaceous when previously only megaspores attributed to the family occurred during this time.
Cainozoic ferns and their distribution
The phytogeographic distribution of Cainozoic ferns is reported based upon a critical re-appraisal of the macrofossil and mesofossil record also taking account of evidence from a few highly
