A Middle to Late Miocene Trans-Andean Portal: Geologic Record in the Tatacoa Desert
Frontiers in Earth Science, 2021 Integration of several geologic lines of evidence reveals the prevalence of a lowland trans-Andean portal communicating western Amazonia and the westernmost Andes from at least middle Miocene until Pliocene times.

Middle Miocene long-term continental temperature change in and out of pace with marine climate records. [PDF]
Sci Rep, 2020 Reconstructing long-term continental temperature change provides the required counterpart to age equivalent marine records and can reveal how terrestrial and marine temperatures were related during times of extreme climate change such as the Miocene ...

Ocean Carbon Storage across the middle Miocene: a new interpretation for the Monterey Event. [PDF]
Nat Commun, 2020 The Miocene Climatic Optimum (MCO, 14–17 Ma) was ~3–4 °C warmer than present, similar to estimates for 2100. Coincident with the MCO is the Monterey positive carbon isotope (δ13C) excursion, with oceans more depleted in 12C relative to 13C than any time ...

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Middle Miocene Climate and Stable Oxygen Isotopes in Europe Based on Numerical Modeling
Paleoceanography and Paleoclimatology, 2022 The Middle Miocene (15.99–11.65 Ma) of Europe witnessed major climatic, environmental, and vegetational change, yet we are lacking detailed reconstructions of Middle Miocene temperature and precipitation patterns over Europe.

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 ...

Decrease in coccolithophore calcification and CO2 since the middle Miocene. [PDF]
Nat Commun, 2016 Marine algae are instrumental in carbon cycling and atmospheric carbon dioxide (CO2) regulation. One group, coccolithophores, uses carbon to photosynthesize and to calcify, covering their cells with chalk platelets (coccoliths).

Initiation of the Western Pacific Warm Pool at the Middle Miocene Climate Transition?
Paleoceanography and Paleoclimatology, 2020 Across the middle Miocene, Earth's climate underwent a major cooling and expansion of the Antarctic ice sheet. However, the associated response and development of the tropical climate system is not fully understood, in part because this is influenced by ...
