New Constraints on the Onset of Antarctic Glaciation From Combined Radiogenic Hafnium and Neodymium Isotopes

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The drawdown of atmospheric CO2 likely triggered Antarctic glaciation during the Eocene‐Oligocene Transition (34 Ma). Accurately constraining this shift from “greenhouse” to an “icehouse” climate is essential for understanding global carbon cycle dynamics.

Calcareous Nannofossils in Middle Triassic (Anisian) - A preliminary note

Geologija, 1991
In this note nannofossils of Anisian age are reported in a Middle Triassic flysch sequence in southern Montenegro (Dinarides). The rich and various nannofossils are largely different from those described either in Paleozoic-Upper Triassic or in younger rocks.

Orbital Control of Reticulofenestra (Calcareous Nannofossils) Assemblages During the Early Pliocene

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Orbital changes have shaped Earth's climate system and influenced the evolution and spatial distribution of marine plankton, including coccolithophores. Some studies have assessed eccentricity's impact on the diversity and morphological evolution of Noelaerhabdaceae taxa during the Quaternary.
