Phytoplankton dynamics from the Cambrian Explosion to the onset of the Great Ordovician Biodiversification Event: a review of Cambrian acritarch diversity [PDF]
, 2015 Most early Palaeozoic acritarchs are thought to represent a part of the marine phytoplankton and so constituted a significant element at the base of the marine trophic chain during the ‘Cambrian Explosion’ and the subsequent ‘Great Ordovician ...

Tropical Warming and Intensification of the West African Monsoon During the Miocene Climatic Optimum
Paleoceanography and Paleoclimatology, Volume 39, Issue 5, May 2024.Abstract Studying monsoon dynamics during past warm time periods such as the Miocene Climatic Optimum (MCO; ∼16.9–14.5 Ma) could greatly aid in better projecting monsoon intensity, in the context of future greenhouse warming. However, studies on regional MCO temperature change and its effect on the monsoons during this time period are lacking. Here, we

Acritarchs of the Ediacaran Frecheirinha Formation, Ubajara Group, Northeastern Brazil
Anais da Academia Brasileira de Ciências, 2015 We report for the first time the occurrence of organic-walled microfossils in Ediacaran limestones and marls of the Frecheirinha Formation, Ubajara Group, and the first Precambrian acritarchs so far reported for northeastern Brazil. The assemblage of the
