Analysis of the environmental magnetic properties of the 624.15-m CRP-2/2A core, from McMurdo Sound, Antarctica, suggests that the core can be divided into three intervals, based on the nature and abundance of the magnetic minerals in the sedimentary sequence. These variations in magnetic parameters do not appear to be directly related to lithological variations in the core. Above 270 metres be...

a total of 12 species of marine gastropods, among which two taxa are new, is reported for the first time from the miocene deposits of khavich section, south of sirjan, kerman. gastropods assemblage in khavich area indicates deposition in shallow, warm ramp-type carbonate platform. the miocene and even oligocene gastropod assemblages, relatively similar to khavich section, reported from the othe...

Three independent methods: paleomagnetic investigation, analysis of reflection seismic sections and structural study of outcrops have been applied to MesozoicTertiary rocks of the Mecsek and Villány Mts (SW Hungary), which form inselbergs in the southern part of the Pannonian Basin. The structural history is marked by Late OligoceneEarly Miocene NW-SE shortening (in present cooridinates); late ...

A Fossil Mounded Sedimentary Body (MB) has been identified in the sedimentary record on the central continental rise west of Adelaide Island, on the Antarctic Peninsula Pacific margin. The growth patterns of the MB are defined through a detailed regional stratigraphic analysis using multichannel seismic reflection profiles. The MB has an elongated NE trend. It overlaps and continues to the NE o...

New compression leaf material of Ceratozamia (Zamiaceae) has been recognised in the European Cenozoic. A leaflet of Ceratozamia floersheimensis (Engelhardt) Kvaček was recovered among unidentified material from the Oligocene of Trbovlje, former Trifail, Slovenia, housed in old collections of the Austrian Geological Survey, Vienna. It is similar in morphology and epidermal anatomy to other speci...

A new genus and species of hipposiderid bat is described from an early Miocene cave deposit (Bitesantennary Site) in the Riversleigh World Heritage fossil property, northern Australia. Eight hipposiderid genera are now recorded from Riversleigh’s Miocene sediments: Hipposideros, Brachipposideros, Rhinonycteris, Riversleigha, Xenorhinos, Miophyllorhina, Archerops and Brevipalatus gen. nov. The n...

A series of Oligocene through Early Miocene terrestrial deposits preserved in the foothills of the Zinda Pir Dome of western Pakistan produce multiple, superposed fossil mammal localities. These include small mammal assemblages that shed light on the evolution of rodent lineages, especially Muroidea, in South Asia. Nine small mammal localities span approximately 28-19 Ma, an interval encompassi...

Although the permanently to seasonally ice-covered Arctic Ocean is a unique and sensitive component in the Earth's climate system, the knowledge of its long-term climate history remains very limited due to the restricted number of pre-Quaternary sedimentary records. During Polarstern Expedition PS87/2014, we discovered multiple submarine landslides along Lomonosov Ridge. Removal of younger sedi...
