Angiosperms (flowering plants) are the most diverse of all major lineages of land plants and the dominant autotrophs in most terrestrial ecosystems. Their evolutionary and ecological appearance is therefore of considerable interest and has significant implications for understanding patterns of diversification in other lineages, including insects and other animals. More than half a century ago, influential reviews showed that while angiosperms are richly represented in sediments of Late… 

Origin of angiosperms and the puzzle of the Jurassic gap

A study reconstructed angiosperm phylogeny on the basis of plastome data representing 2,351 angiosperm and 187 gymnosperm species, and dated the origin of crown angiosperms to be significantly earlier than the estimates based on fossil data.

How deep is the conflict between molecular and fossil evidence on the age of angiosperms?

Paleobotanical evidence on the age of angiosperms is evaluated, showing how fossils provide crucial data for clarifying the situation and examining recently recognized biases in molecular dating to argue that a thoughtful integration of fossil and molecular evidence could help resolve these conflicts.

When and Why Nature Gained Angiosperms

Flowering plants, the angiosperms, are the most diverse group of plants on our planet. Today, they dominate most vegetation types, but their origin continues to remain a mystery. However, we continue

Evidence for an extinct lineage of angiosperms from the Early Cretaceous of Patagonia and implications for the early radiation of flowering plants.

Whereas many Early Cretaceous angiosperms fall within the morphological range of extant taxa, Mesodescolea reveals unexpected early morphological and ecophysiological trends.

Reinvestigating an enigmatic Late Cretaceous monocot: morphology, taxonomy, and biogeography of Viracarpon

The character mosaic observed in Viracarpon and the broad distribution of the genus provide new data relevant to understanding early monocot evolution and suggest that the (thus far) largely invisible Late Cretaceous monocots diversification was characterized by enigmatic and/or stem taxa.

Angiosperms are the single most important plant group in the current ecosystem. However, little is known about the origin and early evolution of angiosperms. Jurassic and earlier traces of

The Early Cretaceous Mesofossil Flora of Torres Vedras (Ne of Forte Da Forca), Portugal: A Palaeofloristic Analysis of an Early Angiosperm Community

An Early Cretaceous mesofossil flora is described from the lower part of the Almargem Formation from Torres Vedras (NE of Forte da Forca), Portugal and shows a marked underestimation of angiosperm diversity in the palynoflora.

Fossil data support a pre-Cretaceous origin of flowering plants.

A Bayesian method is developed to estimate the ages of angiosperm families on the basis of the fossil record (a newly compiled dataset of ~15,000 occurrences in 198 families) and their living diversity and indicates that several families originated in the Jurassic, strongly rejecting a Cretaceous origin for the group.

The delayed and geographically heterogeneous diversification of flowering plant families

A new study of the divergence time of angiosperm families shows that the diversification of families into extant diversity was delayed until the Palaeocene, this time lag being geographically heterogeneous, and longer in tropical than in temperate and arid biomes.

Mitochondrial genes from 18 angiosperms fill sampling gaps for phylogenomic inferences of the early diversification of flowering plants

The early diversification of angiosperms is thought to have been a rapid process, which may complicate phylogenetic analyses of early angiosperm relationships. Plastid and nuclear phylogenomic



The earliest angiosperms: evidence from mitochondrial, plastid and nuclear genomes

This study demonstrates that Amboreella, Nymphaeales and Illiciales-Trimeniaceae-Austrobaileya represent the first stage of angiosperm evolution, with Amborella being sister to all other angiosperms, and shows that Gnetales are related to the conifers and are not sister to the angios perms, thus refuting the Anthophyte Hypothesis.

Molecular and Fossil Evidence on the Origin of Angiosperms

Molecular data on relationships within angiosperms confirm the view that their increasing morphological diversity through the Cretaceous reflected their evolutionary radiation. Despite the early

Angiosperm diversification and Cretaceous floristic trends: a comparison of palynofloras and leaf macrofloras

In the latest Cretaceous, macrofloras and palynofloras both indicate that "pteridophytes," conifers, and other "gymnosperms" are generally less diverse than angiosperms, whereas conifer diversity shows no marked temporal trend.

A boreal early cradle of Angiosperms? Angiosperm-like pollen from the Middle Triassic of the Barents Sea (Norway)

The origin of flowering plants is still a matter of dispute. Several lines of evidence suggest that their origin may go back to the Triassic. This paper reports on pollen grains with angiosperm-like

Associated flowers indicate that palmately lobed ‘platanoids’ and Sapindopsis are both stem relatives of Platanus, while Nelumbites was related to Nelumbo (also Proteales) and Spanomera to Buxaceae.

Integrating Early Cretaceous Fossils into the Phylogeny of Living Angiosperms: ANITA Lines and Relatives of Chloranthaceae

The results reaffirm the early diversity of Chloranthaceae and clarify their floral evolution, in which a shift to unisexual flowers preceded loss of the perianth.

Resolution of deep angiosperm phylogeny using conserved nuclear genes and estimates of early divergence times

The molecular clock estimates of Mesangiospermae diversification during the late to middle Jurassic correspond well to the origins of some insects, which may have been a factor facilitating early angiosperm radiation.

Evolution of the angiosperms: calibrating the family tree

Angiosperm divergence times are estimated using non–parametric rate smoothing and a three–gene dataset covering ca.

Exceptional preservation of tiny embryos documents seed dormancy in early angiosperms

The discovery of embryos and their associated nutrient storage tissues in exceptionally well-preserved angiosperm seeds from the Early Cretaceous support hypotheses based on extant plants that tiny embryos and seed dormancy are basic for angiosperms as a whole.

Schmeissneria: An angiosperm from the Early Jurassic

The syntype and new materials of Schmeissneria collected previously in Germany and recently in China are studied and it is shown that the fruits in these infructescences have in situ seeds enclosed, and that the ovaries are closed before pollination, which will extend the record of angiosperms up to the Early Jurassic.
