Comment on “An early Miocene extinction in pelagic sharks” [PDF]

open access: yesScience, 2021
Sibert and Rubin (Reports, 4 June 2021, p. 1105) report an early Miocene extinction in pelagic sharks based on the loss of shark denticle diversity in two widely separated deep-sea sediment cores. We assert that the pattern observed is not a consequence of extinction but results from shifting species ranges induced by global current reorganization.

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.

Yellowstone plume drives drainage reorganization in the early Miocene. [PDF]

open access: yesSci Adv
The rise of the Yellowstone plume coincided with a shift from orogenic collapse of the Cordillera to Basin and Range extension in the northern Rocky Mountains, yet its impact on regional uplift, sediment dispersal, and drainage patterns remains largely unexplored.

Phylogenetically informative proteins from an Early Miocene rhinocerotid. [PDF]

open access: yesNature
In the past decade, ancient protein sequences have emerged as a valuable source of data for deep-time phylogenetic inference1-4. Still, even though ancient proteins have been reported from the Middle-Late Miocene5,6, the recovery of protein sequences providing subordinal-level phylogenetic insights does not exceed 3.7 million years ago (Pliocene)1 ...

Volcanic contribution to emergence of Central Panama in the Early Miocene. [PDF]

open access: yesSci Rep, 2019
AbstractFormation of the Panama Isthmus, that had global oceanographic and biotic effects in the Neogene, is generally associated with tectonic uplift during collision of the Panama volcanic arc with South America. However, new field, geochemical and geochronological data from the Culebra Cut of the Panama Canal suggest that volcanism also contributed ...

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.

Middle Miocene otoliths of freshwater fishes from the Vračević Lake (Serbian Lake System) [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2021
The Serbian Lake System (SLS) is a key area for early to middle Miocene freshwater environments in southeastern Europe. Here, we describe a rich fossil association of freshwater fish otoliths of late Badenian to early Sarmatian (Serravallian, MN 7+8 zone)

Antarctic ice sheet and oceanographic response to eccentricity forcing during the early Miocene [PDF]

open access: yes, 2011
Stable isotope records of benthic foraminifera from ODP Site 1264 in the southeastern Atlantic Ocean are presented which resolve the latest Oligocene to early Miocene (~24–19 Ma) climate changes at high temporal resolution (<3 kyr).

Provenance Shifts During Neogene Brahmaputra Delta Progradation Tied to Coupled Climate and Tectonic Change in the Eastern Himalaya

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The Bengal Basin preserves the erosional signals of coupled tectonic‐climatic change during late Cenozoic development of the Himalayan orogen, yet regional correlation and interpretation of these signals remains incomplete.
