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… Expand
Origin of angiosperms and the puzzle of the Jurassic gap
TLDR
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. Expand
How deep is the conflict between molecular and fossil evidence on the age of angiosperms?
TLDR
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. Expand
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 continueExpand
Evidence for an extinct lineage of angiosperms from the Early Cretaceous of Patagonia and implications for the early radiation of flowering plants.
TLDR
Whereas many Early Cretaceous angiosperms fall within the morphological range of extant taxa, Mesodescolea reveals unexpected early morphological and ecophysiological trends. Expand
Reinvestigating an enigmatic Late Cretaceous monocot: morphology, taxonomy, and biogeography of Viracarpon
TLDR
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. Expand
The Early Cretaceous Mesofossil Flora of Torres Vedras (Ne of Forte Da Forca), Portugal: A Palaeofloristic Analysis of an Early Angiosperm Community
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 Forca), Portugal. The floraExpand
Fossil data support a pre-Cretaceous origin of flowering plants.
TLDR
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. Expand
The delayed and geographically heterogeneous diversification of flowering plant families
TLDR
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. Expand
Phylogenomic Insights into Deep Phylogeny of Angiosperms Based on Broad Nuclear Gene Sampling
TLDR
The analyses suggest that a fully bifurcating species tree may not be the best way to represent the early radiation of angiosperms and that eudicots, Ceratophyllales, and Chloranthales form a clade, with magnoliids and monocots being the next successive sister lineages. Expand
An unexpected noncarpellate epigynous flower from the Jurassic of China
TLDR
Evidence of an actinomorphic flower with a dendroid style, cup-form receptacle, and angiospermy, is consistent with Nanjinganthus being a bona fide angiosperm from the Jurassic, an inference that it is hoped will re-invigorate research intoAngiosperm origins. Expand

The earliest angiosperms: evidence from mitochondrial, plastid and nuclear genomes
TLDR
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 earlyExpand
Angiosperm diversification and Cretaceous floristic trends: a comparison of palynofloras and leaf macrofloras
TLDR
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. Expand
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-likeExpand
Recognising angiosperm clades in the Early Cretaceous fossil record
TLDR
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. Expand
Integrating Early Cretaceous Fossils into the Phylogeny of Living Angiosperms: ANITA Lines and Relatives of Chloranthaceae
TLDR
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. Expand
Resolution of deep angiosperm phylogeny using conserved nuclear genes and estimates of early divergence times
TLDR
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. Expand
Exceptional preservation of tiny embryos documents seed dormancy in early angiosperms
TLDR
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. Expand
Evolution of the angiosperms: calibrating the family tree
TLDR
Angiosperm divergence times are estimated using non–parametric rate smoothing and a three–gene dataset covering ca. Expand
Schmeissneria: An angiosperm from the Early Jurassic
TLDR
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.
