Recently published diatom biochronologies provide accurate (to 0.1 m.y.) determination of the ages of appearances and disappearances of planktonic diatoms during the past 18 m.y. in the equatorial Pacific, North Pacific, and Southern Ocean. Comparisons of these records reveal the age of evolutionary appearance and extinction of species and their region of origin. Extinct planktonic diatom species have a mean longevity of 3.4 ± 2.8 m.y. (SD, n = 53) in the equatorial Pacific, 2.5 ± 2.1 m.y. (n…

Neogene diatoms from the Southern Ocean; tiny fossils, big questions

The Neogene (c. 23-2.6 Ma) is the most recent period of Earth history in which atmospheric CO2 was last >400 ppm; possibly associated with dramatic fluctuations in Antarctic ice volume and thus

Neogene Radiolarian Biostratigraphy and Faunal Evolution Rates in the Eastern Equatorial Pacific ODP Sites 845 and 1241

Radiolarians from Sites 845 and 1241 in the eastern equatorial Pacific were examined in order to evaluate the role of paleoceanographic perturbations upon the general faunal evolutionary pattern of

Evolutionary Trajectories and Biogeochemical Impacts of Marine Eukaryotic Phytoplankton

TLDR
The evolutionary succession of marine photoautotrophs began with the origin of photosynthesis in the Archean Eon, and three groups of chlorophyll c–containing eukaryotes, the dinoflagellates, coccolithophorids, and diatoms began evolutionary trajectories that have culminated in ecological dominance in the con...

New Miocene Sulid Birds from Peru and Considerations on their Neogene Fossil Record in the Eastern Pacific Ocean

TLDR
Three new species of sulids are described, relatives of the living genus Sula, which represents medium and large-sized boobies, from the early Late Miocene of the Pisco Formation (Peru), finding current analysis and knowledge of the fossil record unsuitable to evaluate properly seabird diversity changes through time.
