The Paleocene flora from Seymour Island, Antarctica, is one of the most diverse floras of this age in the Southern Hemisphere. First collected on the Swedish South Polar Expedition (1901–1903), it was described by Dusén in 1908 as having 87 leaf taxa. Forty-seven angiosperm taxa were described and/or illustrated. Many species are based on single specimens, and the flora has not been re-examined in its entirety since it was first described. This study is the first reassessment of the flora… 

Revision of Frenguelli's (1941) Patagonian Angiosperm Fossil Leaf Collection with Comments on the Original Localities (Eocene–Miocene)

Abstract. Frenguelli described a fossil leaf assemblage of 36 taxonomic units (nine gymnosperms and 27 angiosperms) collected from ten localities in southwestern Patagonia. Frenguelli's article has

Paleofloristic assemblage from the Paleogene Río Guillermo Formation, Argentina: preliminary results of phylogenetic relationships of Nothofagus in South America

The preliminary results support the hypothesis that fossil species of Nothogafus are closely related to the modern species as well as characteristic species from a temperate-cold climate such as the genus Nothofagus.

First South American Record of Winteroxylon, Eocene of Laguna del Hunco (Chubut, Patagonia, Argentina): New Link to Australasia and Malesia

Premise of research. Winteraceae, a family within the Canellales, is composed of tropical trees and shrubs broadly distributed in the Southern Hemisphere. The family is found today in eastern


Early Paleocene macrofloras from the Southern Hemisphere are little known, despite their significance for understanding plant evolution, biogeography, and global variation in recovery after the

Fossil plants in the Tierra del Fuego Province, Argentinean Patagonia, are known since the expedition of Charles Darwin to the Beagle channel. However, only a few fossil plants have been described.

The first exciting clues that Antarctica had not always been ice-covered were the leaf fossils of Glossopteris plants that Scott’s party brought back from the Beardmore Glacier region in 1912.



Paleocene flora from Seymour Island, Antarctica: revision of Dusén's (1908) pteridophyte and conifer taxa

The Paleocene flora from Seymour Island, Antarctica, first collected by Nordenskjöld on the Swedish South Polar Expedition (1901–1903), was described by Dusén (1908) as having 87 leaf taxa making it

Monimiaceae sensu lato, an element of Gondwanan polar forests: Evidence from the late Cretaceous-early tertiary wood flora of Antarctica

Two previously unrecognised morphotypes, which can be assigned to the Monimiaceae sensu lato, are described, and represents the first record of this family in the wood flora of Antarctica.

Systematics of cretaceous and tertiary Nothofagoxylon: implications for Southern Hemisphere biogeography and evolution of the Nothofagaceae

Temporal and spatial patterns of occurrence of the Nothofagoxylon wood type help support current views that the centre of origin of theNoth ofagaceae was within the Antarctic Peninsula–South America region during the Campanian followed by radiation into the lower southern latitudes throughout the Tertiary.


New elements of the La Meseta Formation megaflora are described. This unit crops out on the northern third of Marambio (Seymour) Island, Antarctica. Fossil leaves were collected from the middle part

Cretaceous angiosperm leaf floras from Antarctica

Late Cretaceous angiosperm leaf floras from the Antarctic Peninsula have been studied and described for the first time. The Hidden Lake Formation (Coniacian) and Santa Marta Formation

Maastrichtian to Paleocene dinocysts from the Clarence Valley, South Island, New Zealand

A palynological study of uppermost Maastrichtian to lower Paleocene marine strata from two stratigraphic sections in the Clarence Valley, Marlborough, New Zealand, revealed diverse organic-walled

A Paleocene lowland macroflora from Patagonia reveals significantly greater richness than North American analogs

Few South American macrofloras of Paleocene age are known, and this limits our knowledge of diversity and composition between the end-Cretaceous event and the Eocene appearance of high floral

Paleogene phytogeography and climatology of South America

The purpose of the present work is to review the Paleogene taphofloras of South America and to analyze their paleophytogeographical and paleoclimatical significance, and to agree on the terminology used in biogeographical discussions, especially among paleobotanists.

Fossil nothofagaceous leaves from the Eocene of western Antarctica and their bearing on the origin, dispersal and systematics of Nothofagus

  • Liang Hao

It is concluded that Nothofagus probably originated in high latitudes of the Southern Hemisphere during the middle-late Late Cretaceous and diversified, dispersed gradually to the lower latitude of the same hemisphere and leaf morphological characters are significant for the systematics of the family Noth ofagaceae.
