New late Cenozoic acritarchs: evolution, palaeoecology and correlation potential in high latitude oceans
Acritarchs have received limited attention in palynological studies of the Cenozoic, although they have much potential both for refining Neogene and Quaternary stratigraphy, especially in mid- and high northern latitudes, and developing palaeoceanographical reconstructions. Here we formally describe...
