Data from: Origin of angiosperms and the puzzle of the Jurassic gap

Angiosperms are by far the most species-rich clade of land plants, but
their origin and early evolutionary history remain poorly understood. We
reconstructed angiosperm phylogeny based on 80 genes from 2,881 plastid
genomes representing 85% of extant families and all orders. With a
well-resolved plastid tree and 62 fossil calibrations, we dated the origin
of the crown angiosperms to the Upper Triassic, with major angiosperm
radiations occurring in the Jurassic and Lower Cretaceous. This estimated
crown age is substantially earlier than that of unequivocal angiosperm
fossils, and the difference is here termed the ‘Jurassic angiosperm gap’.
Our time-calibrated plastid phylogenomic tree provides a highly relevant
framework for future comparative studies of flowering plant evolution.
