The recently discovered amber biota from Zhangpu, China, offers a unique window into the tropical ecosystem of an Asian rainforest during the Mid-Miocene Climatic Optimum (MMCO). Here, the first flat wasp (Bethylidae) from this deposit is documented: Parascleroderma palaeosinica n. sp. is described and figured from a single male, and is the first f...
The Miocene fossil record of Chrysidoidea is particularly scarce despite numbers of insect-bearing deposits available. Their record is here summarized, highlighting the overwhelming proportion of fossils from Dominican Republic amber while other deposits, e.g., Zhangpu, Mexican or Ethiopian ambers, seem promising for the study of the group but suff...
Despite their ecological importance, Darwin wasps (Ichneumonidae) are among the most poorly studied groups of organisms. It is therefore not surprising that their fossil record is even more poorly understood than their extant diversity. The early Eocene seems rather fossil-poor regarding Ichneumonidae in amber and only one species, Palaeometopius e...
The fossil record of octocorals from Cenozoic marine strata of western North America is quite limited, and they have not been reported previously from rocks in Washington State, USA. Two late Oligocene specimens from the upper part of the Lincoln Creek Formation in western Washington, referred to Radicipes? sp., are the first fossil record of the f...
The fossil diversity of Diapriidae in Baltic amber, dated Upper Eocene, has been poorly investigated. However, some studies suggest that this family was already diversified at this time. This is supported by our present study of the Baltic amber collection of the Natural History Museum of Denmark, from which we describe and figure ten new species b...

The Cenozoic tectonic evolution of the North Qaidam-Qilian Shan fold-thrust belt in the northern Tibetan Plateau is important to understanding the tectonic rejuvenation of orogeny and growth of the plateau. However, the deformation processes in this region remain controversial. This study presents new apatite fission track (AFT) data from Paleogene...

The chemical weathering of sulfide-bearing rocks can result in the dissolution of carbonate rocks leading to degassing of (Formula presented.) to the atmosphere. While this process has been argued to be a significant geologic source of (Formula presented.), it also perturbs the geological cycles of oxygen and sulfur, triggering a cascade of geochem...
