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

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.

Diversification of Eupolypods in Mid-Cretaceous—Evidenced by Myanmar Amber Forest

The evolutionary history of Eupolypods still remains unclear, especially on its diversification scenarios. In recent years, it has been found that approximately 100 million-year-old Myanmar amber

Monotypic colonies of Clathropteris meniscioides (Dipteridaceae) from the Early Jurassic of central Patagonia, Argentina: implications for taxonomy and palaeoecology

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

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.

Assessing the evolutionary history of the fern family Dipteridaceae (Gleicheniales) by incorporating both extant and extinct members in a combined phylogenetic study.

Dipteridaceae was found to be monophyletic and characterized by highly anastomosing minor veins forming a meshwork of areoles with free-included veinlets.

REASSIGNMENT OF ASPIDIUM HETEROPHYLLUM TO A NEW GENUS IN THE FAMILY M ATONI ACE AE

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.

A comparison with other azollaceous and salviniaceous genera, particularly Azolla, is provided, together with a discussion of some evolutionary trends within the family.
