A new fossil dolphin Dilophodelphis fordycei provides insight into the evolution of supraorbital crests in Platanistoidea (Mammalia, Cetacea) [PDF]

open access: yesRoyal Society Open Science, 2017
Many odontocete groups have developed enlarged facial crests, although these crests differ in topography, composition and function. The most elaborate crests occur in the South Asian river dolphin (Platanista gangetica), in which they rise dorsally as ...

Depositional characteristics and evolution of Miocene deep-water channel systems in block A of Lower Congo-Congo Fan Basin, West Africa

open access: yesShiyou shiyan dizhi, 2021
Researches on the depositional characteristics, evolution and constraining factors of deep-water channel systems are the key factors to reveal the "source-sink" process at continental margin and make big breakthroughs in deep-water hydrocarbon ...

A mid-miocene age for the Slanci formation near Belgrade (Serbia), based on a record of the primitive antelope Eotragus cf. Clavatus from Višnjica [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2007
In a borhole at Veliko Selo near Belgrade in the Miocene lacustrine sediments Slanci, which are locally known as the Slanačka Serija, a mammal tooth was found. The age of these deposits is under discussion.

The relative roles of CO2 and palaeogeography in determining Late Miocene climate: results from a terrestrial model-data comparison [PDF]

open access: yes, 2012
The Late Miocene (∼11.6–5.3 Ma) palaeorecord provides evidence for a warmer and wetter climate than that of today and there is uncertainty in the palaeo-CO2 record of at least 150 ppmv.

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 revision of the fossil genus Miocepphus and other Miocene Alcidae (Aves: Charadriiformes) of the Western North Atlantic Ocean [PDF]

open access: yes, 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 ...
