(2015) predict angiosperm occurrences in Anisian times and places, which are supported by Hochuli and Feist-Burkhardt palynological data (2004, 2013), and a calibrated phylogenomic timescale (C. Further, Hochuli and Feist-Burkhardt data (2004, 2013) are unequivocal. (2005) underscore the importance of studying poorly known Mesozoic gymnosperms in order to elucidate the roots of the angiosperm stem group. Stem group flowering plants are almost completely unknown except for tantalizing clues to their existence from fossil finds of angiosperm palynomorphs, which were recovered from deeply buried Middle Triassic sediments and later discussed by Hochuli and Feist-Burkhardt (2013). Pictured to the left is a flower of Protea compacta (Proteaceae, Proteales, Proteanae) photographed by the author. Despite considerable discussion in the literature on angiosperm phylogeny and evolution by M. Time-calibrated phylogenies, which are based on chloroplast genomes from several angiosperm species, paint a different evolutionary scenario (C. Permian delnorteas and evolsonias probably fit this bill but more paleobotanical field work is needed to match the detached pieces to the whole mother plant. (2015) supporting Triassic age estimates for flowering plants. The clade probably first appeared during Triassic times, possibly as a result of the re-setting of plant evolutionary history following the devastating global extinction event of the Permian Triassic boundary ..." (4. Detailed studies of the reproductive morphology of Sanmiguelia have been published (Cornet 1989). (2017) should have re-evaluated the morphology and anatomy of Sanmiguelia lewisii before publishing their review in Nature. Detailed discussion is published in Chapter 22 of the most recent comprehensive treatise on fossil angiosperms (T. Certain fossil species reported in the scientific literature are not assignable to any extant angiosperm subclass.
