The timing of the origin of angiosperms is a hotly debated topic in plant evolution. Molecular
dating analyses that consistently retrieve pre‐Cretaceous ages for crown‐group …

Recently, evolutionary relationships among the five major lineages of the basal
angiosperms, ie, Amborellanae, Nymphaeanae, Austrobaileyanae, Magnolianae, and …

Premise of research. Discoveries of fossil flowers in Cretaceous rocks offer improved
evidence for relationships with living clades, but for more secure inferences formal …

The classic leaf fossil floras from the Cretaceous of the Lusitanian Basin, Portugal, which
were first described more than one hundred years ago, have played an important role in the …

Abstract An Early Cretaceous mesofossil flora is described from the lower part of the
Almargem Formation (late Barremian-early Aptian) from Torres Vedras (NE of Forte da …

Chloranthaceae were one of the first common lines during the early radiation of
angiosperms, possibly reflecting adaptation to more open habitats. Phylogenetic analyses …

In comparison to the early and middle Eocene, the late Eocene and particularly the
Oligocene floral record is sparse in North America. Changing tectonic, environmental and …

Monocots, with ca. 65,000 species in 78 families and 12 orders as classified by the
Angiosperm Phylogeny Group (Angiosperm Phylogeny Group III, 2009), have traditionally …

One inaperturate and 16 monosulcate pollen types are described from the latest Campanian
to earliest Maastrichtian sediments of the Vilui basin, Siberia, using both light and scanning …

The small aquatic family Hydatellaceae was recently assigned to the early‐divergent
angiosperm order Nymphaeales. Pollen morphology is described using both SEM and LM …
