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.

Late middle Miocene caviomorph rodents from Tarapoto, Peruvian Amazonia. [PDF]

open access: yesPLoS One, 2021
Miocene deposits of South America have yielded several species-rich assemblages of caviomorph rodents. They are mostly situated at high and mid- latitudes of the continent, except for the exceptional Honda Group of La Venta, Colombia, the faunal composition of which allowed to describe the late middle Miocene Laventan South American Land Mammal Age ...

Systematic taxonomy of middle MioceneSphaeroidinellopsis(planktonic foraminifera) [PDF]

open access: yesJournal of Systematic Palaeontology, 2021
The taxonomy and phylogeny of the Miocene to Recent genus Sphaeroidinellopsis have been documented in previous studies, but the evolution of this lineage remains unclear. Some authors have debated this genus in the past, choosing a variety of parameters to discriminate the morphospecies.

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 ...

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 ...
