A pan-cheloniid turtle from the Middle Miocene of Portugal. [PDF]

open access: yesAnat Rec (Hoboken)
AbstractCurrently, there is no information on the fossil record of Pan‐Cheloniidae from the Neogene of the Iberian Peninsula. A well‐preserved partial skeleton attributable to this lineage of turtles, from the Middle Miocene of Portugal, is presented here.

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical 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.

A Middle to Late Miocene Trans-Andean Portal: Geologic Record in the Tatacoa Desert

open access: yesFrontiers 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.

Stratigraphic implications of the Middle Miocene of the Despotovac area: Recognition of two geological formations [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva
The Middle Miocene of the Despotovac area contains sediments of the lower Middle Miocene (Badenian) and upper Middle Miocene (Sarmatian). The Middle Miocene deposition shows different local variations, but generally fits the evolution of the Central ...

The identification of Oligo-Miocene mammalian palaeocommunities from the Riversleigh World Heritage Area, Australia and an appraisal of palaeoecological techniques [PDF]

open access: yesPeerJ, 2017
Fourteen of the best sampled Oligo-Miocene local faunas from the Riversleigh World Heritage Area, north-western Queensland, Australia are analysed using classification and ordination techniques to identify potential mammalian palaeocommunities and ...

Decrease in coccolithophore calcification and CO2 since the middle Miocene. [PDF]

open access: yesNat Commun, 2016
AbstractMarine 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). How ocean acidification influences coccolithophore calcification is strongly debated, and the effects of carbonate ...

A new Middle Miocene selachian assemblage (Chondrichthyes, Elasmobranchii) from the Central Paratethys (Nyirád, Hungary): implications for temporal turnover and biogeography

open access: yesGeologica Carpathica, 2016
A new Middle Miocene (Langhian - early Serravallian) assemblage with shark and ray teeth from Nyirád (Hungary, Transdanubia, Veszprém County) consists of nine families, with 15 different species. The assemblage shares many common genera with other Middle

Sedimentary responses of tectonic events in Miocene, western margin of South China Sea: a case study of Wan'an Basin

open access: yesShiyou shiyan dizhi, 2021
The Wan'an Basin is located on the southwestern margin of the South China Sea, and its unique tectonic position has made its filling evolution an important window to study the expansion of the southwest submarine basin and the strike-slip faults on the ...

Simulation of the Middle Miocene Climate Optimum [PDF]

open access: yesGeophysical Research Letters, 2009
Proxy data constraining land and ocean surface paleo‐temperatures indicate that the Middle Miocene Climate Optimum (MMCO), a global warming event at ∼15 Ma, had a global annual mean surface temperature of 18.4°C, about 3°C higher than present and equivalent to the warming predicted for the next century.
