• Late Eocene continental climate in Central Asia remains poorly understood. Tibetan lake deposits preserve records of palaeoenvironmental changes. Saline lakes east-central Tibet existed a cool and semi-arid desert-steppe. aridification caused shift Asia. palaeoclimate was primarily influenced by regional to global drivers. Ancient detailed Cenozoic environmental changes, providing information...
The late Miocene evolution of the Mediterranean Basin is characterized by major changes in connectivity, climate and tectonic activity resulting unprecedented environmental ecological disruptions. During Messinian Salinity Crisis (MSC, 5.97-5.33 Ma) this culminated most scenarios first precipitation gypsum around margins (Stage 1, 5.97-5.60 subsequently > 2 km halite on basin floor, which forme...
Abstract The first deep-sea drilling expedition in the Mediterranean chanced upon unanticipated discoveries when recovering deeply buried sediments of Late Miocene age that had once accumulated ultra-shallow water and later experienced subaerial exposure. Among these deposits were potassium magnesium chlorides, desiccation cracks, fluvial gravels shale bearing bottom-dwelling diatoms requiring ...
The Messinian Salinity Crisis (MSC) successions record extreme fluctuations in the Mediterranean's environmental conditions. However, some of scenarios that are thought to have caused these environments contentious. One prominent example this is Mediterranean water level during Lago-Mare stage MSC, which interpreted either as being very low a largely desiccated punctuated by endorheic lakes (la...
Sirenia are marine mammals that colonized the European shores up to 2.7 Ma. Their biodiversity evolution follows the climate evolution of the Cenozoic. However, several climate events, as well as the global climate trend of this Era are still struggling to be understood. When considering only Earth processes, the climate evolution of the Cenozoic is hard to understand. If the galactic environme...
Clinoforms and clinothems are important common architectural elements in the sedimentary record of many basins worldwide. The influence that they exert on chronostratigraphic interpretations, however, is often underestimated. This especially true non-marine basins, such as Central European to Asian Neogene Paratethyan where division correlation usually based fossils environmentally sensitive mo...
Cross-correlation between insolation intensities and a combination of sedimentary characters is introduced to obtain precise time calibration of sedimentary cycles. The first step is to transfer the section scale into ages using power spectra comparing the main periods with orbital cycles, while in the second step the standardized values of sedimentary signals are cross-correlated with the stan...
Toadfishes (Batrachoidiformes) are benthic fishes often burying in the sand or under rocks that occur worldwide in tropical to temperate marine and brackish waters. The Batrachoididae, the only known family of the order Batrachoidiformes, includes 23 extant genera and about 80 species arranged in four subfamilies. A new genus and species of toadfish, yZappaichthys harzhauseri, gen. et sp. nov.,...
