Fossils preserved in amber may provide significant palaeoevolutionary and biogeographical data regarding the evolution of life on Earth1. Although amber is particularly noted for its detailed preservation of arthropods, the same degree of preservation can be found for vascular plant remains2. Mid-Tertiary Dominican amber is a rich source for such fossils, and representatives of several angiosperm families have been described. However, no fossilized examples of the large asterid plant clade have… Expand
New clues on anuran evolution: the oldest record of an extant hyloid clade in the Oligocene of Patagonia
TLDR
The Oligocene Odontophrynidae record represents the single pre-Neogene certain record of an extant clade deeply nested in Hyloidea, providing an exceptional high-quality calibration point to temporally frame the anuran phylogeny. Expand
100-million-year-old conifer tissues from the mid-Cretaceous amber of Charente (western France) revealed by synchrotron microtomography.
TLDR
An exquisitely preserved conifer leafy axis from 100-million-year-old opaque amber of western France that is assignable to Glenrosa carentonensis Moreau, Néraudeau, Tafforeau & Dépré is reported. Expand
Colourful cones: how did flower colour first evolve?

TLDR
How the ancestral flowering plants could have overcome the inevitable trade-off that exists between attracting pollinators and minimising herbivory is investigated, and the possible evolutionary and biological inferences from the colours that occur in some living gymnosperms are explored. Expand

Hymenaea protera sp.n. (Leguminosae, Caesalpinioideae) from Dominican amber has African affinities
TLDR
It is proposed that at least the majority, if not all, of the amber recovered from La Toca mine and other mines in the vicinity with similar-aged deposits originated from H. protera and is interpreted as supporting a hypothesis that the genusHymenaea arose in the late Cretaceous on the combined South American-African continents.

Phylogenetic relationships of the mycoheterotrophic genus Voyria and the implications for the biogeographic history of Gentianaceae.
TLDR
The results suggest that migration of tropical taxa through Laurasia during the Early Eocene has played an important role in shaping the current global distribution of Gentianaceae. Expand
A metacalibrated time-tree documents the early rise of flowering plant phylogenetic diversity.
TLDR
This time-frame documents an early phylogenetic proliferation that led to the establishment of major angiosperm lineages, and the origin of over half of extant families, in the Cretaceous. Expand

TLDR
The updated age estimates for major groups of Rubiaceae provide a significant step forward towards the long term goal of establishing a robust temporal framework for the divergence of this biologically diverse and fascinating group of plants. Expand
Phylogeny and biogeography in Solanaceae, Verbenaceae and Bignoniaceae: a comparison of continental and intercontinental diversification patterns
TLDR
A comparison of clades in each family shows success in most clades at dispersing to, and diversifying in, North America and/or the Caribbean, a mix of adaptation to novel ecological zones and niche conservation, and no association between long-distance dispersal and fleshy, animal-dispersed fruits.
