Eocene Plant Diversity at Laguna del Hunco and Río Pichileufú, Patagonia, Argentina
The origins of South America’s exceptional plant diversity are poorly known from the fossil record. We report on unbiased quantitative collections of fossil floras from Laguna del Hunco (LH) and RíoExpand

Phylogenetic biome conservatism on a global scale
How and why organisms are distributed as they are has long intrigued evolutionary biologists. The tendency for species to retain their ancestral ecology has been demonstrated in distributions onExpand

Testing the impact of calibration on molecular divergence times using a fossil-rich group: the case of Nothofagus (Fagales).
Although temporal calibration is widely recognized as critical for obtaining accurate divergence-time estimates using molecular dating methods, few studies have evaluated the variation resulting fromExpand

Fossil evidence and phylogeny: the age of major angiosperm clades based on mesofossil and macrofossil evidence from Cretaceous deposits.
The fossil record has played an important role in the history of evolutionary thought, has aided the determination of key relationships through mosaics, and has allowed an assessment of a number ofExpand

Oldest Known Eucalyptus Macrofossils Are from South America
The evolutionary history of Eucalyptus and the eucalypts, the larger clade of seven genera including Eucalyptus that today have a natural distribution almost exclusively in Australasia, is poorlyExpand

Phylogenetics, divergence times and diversification from three genomic partitions in monocots
Resolution of evolutionary relationships among some monocot orders remains problematic despite the application of various taxon and molecular locus sampling strategies. In this study we sequenced andExpand

Divisestylus gen. nov. (aff. Iteaceae), a fossil saxifrage from the Late Cretaceous of New Jersey, USA.
Fossilized flowers and fruits from the Upper Cretaceous (Turonian, ca. 90 million years [my] before present) Raritan Formation of New Jersey are described as the new genus Divisestylus with twoExpand

Ontologies as integrative tools for plant science.
PREMISE OF THE STUDY Bio-ontologies are essential tools for accessing and analyzing the rapidly growing pool of plant genomic and phenomic data. Ontologies provide structured vocabularies to supportExpand
