Angiosperms first appeared in northern Gondwana during the Early Cretaceous,
approximately 135 million years ago. Several authors have hypothesised that the origin of …

The isolation of land areas by sea-floor spreading, the uplift of new cordilleras, the
emergence of new archipelagos and the disappearance of old ones, and the shifting …

Morphological, stratigraphic, and sedimentological analyses of Early Cretaceous pollen and
leaf sequences, especially from the Potomac Group of the eastern United States, support the …

Better understanding of the functional biology of early angiosperms may clarify ecological
factors surrounding their origin and early radiation. Phylogenetic studies identify Amborella …

One of the major problems in the study of the evolution of higher plants is the paucity of
evidence from the fossil record on the origin and evolution of the angiosperms. Because of …

This study describes the compositional changes of Mesozoic–Cenozoic palynologic
assemblages in Patagonia, the succession of phytogeographic scenarios and some …

A re-assessment of the Cretaceous succession in the Dakhla area, central Egypt, is
presented on the basis of new palynological evidence from the Six Hills and Maghrabi …

To investigate relationships and character evolution in the angiosperm family
Chloranthaceae, and to integrate fossil specimens into the phylogeny of extant taxa, a …

In this report, we analyze the angiosperm fossil record (micro-and megafossil) from the
central and southern basins of Argentina, southern South America, deposited between the …

Well-preserved and diverse Early Cretaceous palynological assemblages were studied from
an outcrop section of the Springhill Formation at the Río Correntoso locality (PRC), close to …
