The earliest plants generally accepted to be angiospermous are known from the Early Cretaceous Epoch (about 145 million to 100.5 million years ago), though angiosperm-like pollen discovered in 2013 in Switzerland dates to the Anisian Age of the Middle Triassic (about 247.2 million to 242 million years ago), suggesting that angiosperms may have e. 2011; Parham et al.

Potential for paralagous copies of phyA were assessed by a comparison of maximum parsimony analyses that included only phyA sequences to those that included only cpDNA data.

Although a most comprehensive set of fossils is used to estimate ages, and a single fossil should have little impact on the overall age estimations, single fossil inclusion versus exclusion still results in rate alternation of proximal nodes and thus in discrepant age estimates between independent analyses (Figs.

Criteria for selecting a fossil were that it could be placed unambiguously among extant taxa according to synapomorphies or a combination of apomorphies, or that confirmation by phylogenetic analysis is available (on morphological data or combined morphological-molecular analyses) (Gandolfo et al.

This fossil pollen has all the essential features of angiosperm pollen (p. 1, Hochuli and Feist-Burkhardt 2013). Cycadaceae: Therefore, five individual monophyly constraints were set to enforce outgroup position, APG III and APG IV conformity, and comparability between individual analyses comprising: 1) angiosperms, 2) Nymphaeaceae, 3) monocots, Ceratophyllales, eudicots, 4) Magnoliids, and 5) Aristolochiaceae, Lactoridaceae, Asaraceae.

Additionally, the influence of individual calibrations was analyzed as single constraints that were independently excluded from the general analysis (Table 3). The uncorrelated log-normal (UCLN) model, the GTR model and a birth-death process for incomplete sampling as implemented in BEAST were applied to all partitions and analyses. An uncorrelated relaxed-clock analysis suggests an earlier origin for flowering plants. This timeline suggests that the rise of bees coincided with the largest flowering plant clade, the eudicots. Due to the lack of fossils representing the root as well as high likelihood of numerous extinct stem lineages, an exceptionally long branch between extant angiosperms and their extant sister groups persists.
