The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
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 new genus of chemosymbiotic vesicomyid bivalves from the Oligocene of western North America [PDF]
We describe a new genus of the chemosymbiotic bivalve family Vesicomyidae, Squiresica, for two Oligocene species, previously assigned to Archivesica, from western North America.

An Early Oligocene Fossil Lagerstätten from the Lacustrine Deposits of the Luberon UNESCO Global Geopark [PDF]
The Luberon early Oligocene fossil Lagerstätte yields exquisitely well-preserved fossils as testified by the remains of articulated skeletons, skin outlines, feathers and original pigmentation patterns.

Oligocene climate dynamics [PDF]
A planktonic and benthic foraminiferal stable isotope stratigraphy of the Oligocene equatorial Pacific (Ocean Drilling Program, Site 1218) was generated at 6 kyr resolution between magnetochrons C9n and C11n.2n (∼26.4–30 Ma on a newly developed astronomically calibrated timescale).

New material of Epiaceratherium and a new species of Mesaceratherium clear up the phylogeny of early Rhinocerotidae (Perissodactyla) [PDF]
Reduction of the anterior dentition (i.e. incisors and canines) is a major adaptative trait of the Rhinocerotidae among Perissodactyla. However, the corresponding evolutionary sequence was lacking a robust phylogenetic frame to support it thus far. Here,

Paleovegetation and paleoclimate in the Baise Basin during Oligocene
To reconstruct the palaeovegetation and palaeoclimate in the Baise Basin during the Oligocene, in this work, we analyzed sporopollen fossils from the Fuping Formation in this region.
