Ribosomal DNA phylogenies and a morphological revision provide the basis for a revised taxonomy of the Prymnesiales (Haptophyta) (2011, background): “Reports of this species (e.g. Wang & Wang, 1992) have been scarce since its description by Massart (1920) and it has been suggested that P. parvum is identical to P. saltans (e.g. Moestrup, 1994; Guo et al., 1996).”
On the description of Tisochrysis lutea gen. nov. sp. nov. and Isochrysis nuda sp. nov. in the Isochrysidales, and the transfer of Dicrateria to the Prymnesiales (Haptophyta) (2013, background): “The first appearance of alkenones in the sediment archive extends down to the midCretaceous at ca. 120 Mya (Brassell and Dumitrescu 2004), suggesting that the evolutionary origin of the Isochrysidales occurred at or before this period.”
Poleward expansion of the coccolithophore Emiliania huxleyi (2014, background): “…occurring in Pleistocene fossil records 290 000 years BP (Raffi et al., 2006), descended from a lineage that has been phylogenetically separated from most other extant coccolithophores for 195 million years (Medlin et al., 2008) and it rose rapidly to global dominance (Thierstein et al., 1977).”
Environmental controls on coccolithophore calcification (2012, background): “This minimum age for the origin of coccolithophores comes from the fossil record (Falkowski et al. 2004), with the origin of heterococcoliths at least 215 million years ago and of holococcoliths at least 185 million years ago (Medlin et al. 2008).”
Diversity and Ecology of Eukaryotic Marine Phytoplankton (2012, background): “65 Mya, whereas non-calcifying haptophytes were not affected by the K/T extinction (Medlin et al., 2008).”
