The turnover of continental planktonic diatoms near the middle/late Miocene boundary and their Cenozoic evolution. [PDF]
PLoS ONE, 2018 Fossil evidence indicates that modern assemblages of temperate nonmarine planktonic diatoms began near the middle/late Miocene boundary when the genus Actinocyclus, an important constituent of lacustrine planktonic diatom assemblages during the early to ...

A revision of the fossil genus Miocepphus and other Miocene Alcidae (Aves: Charadriiformes) of the Western North Atlantic Ocean [PDF]
, 2009 This study reviews and describes all known fossils of Alcidae from the Miocene of the western North Atlantic. Because the majority of alcid fossils recovered from Miocene sediments are allied with the genus Miocepphus Wetmore, 1940, the genus is revised ...

Late miocene magnetobiostratigraphy of Crete
Marine Micropaleontology, 1984 Six Upper Miocene marine clay sections on Crete (Greece) have been subjected to a detailed magnetobiostratigraphic analysis. Six correlatable polarity zones are recognized and these demonstrate the regional synchrony of planktonic foraminiferal biohorizons.

Seismic stratigraphy and history of deep circulation and sediment drift development in Baffin Bay and the Labrador Sea [PDF]
, 1989 Drilling results and seismic-reflection records at and across Ocean Drilling Program (ODP) Sites 645 (western Baffin Bay), 646, and 647 (Labrador Sea) provide important constraints on the history of deep-water circulation and sedimentation in response to

Late Miocene climate cooling and intensification of southeast Asian winter monsoon
Nature Communications, 2018 The late Miocene offers the opportunity to assess the sensitivity of the Earth’s climate to orbital forcing and to changing boundary conditions, such as ice volume and greenhouse gas concentrations, on a warmer-than-modern Earth.

Tectonic evolution of the southern part of Central Viet Nam and the adjacent area
Геодинамика и тектонофизика, 2018 Interpretations of seismic, gravity and magnetic anomalies and structural data on the coastal zone of southern part of Central Viet Nam (SCVN) and the adjacent Tertiary basins suggest several phases in the tectonic evolution of the study region since the
