Here we attempt to provide first inventory fossil conids from late Crete (Greece). This paper deals with genera Conilithes Conus (Kalloconus) da Motta, 1991 will be followed by papers presenting other family. Using UV light, described residual...

Paleoenvironmental reconstruction of the Mediterranean Basin at end Messinian Salinity Crisis is contentious. One section that records this final phase (Stage 3) Pollenzo Section in Piedmont (NW Italy). Here, we present new stratigraphic, sedimentological, petrographic, micropaleontological (ostracods, calcareous nannofossils, foraminifera, dinoflagellates) and geochemical (87Sr/86Sr ratios) da...
Numerous planktonic species have disjunct distribution patterns in the world's oceans. However, it is unclear whether these are truly unconnected by gene flow, or whether they are composed of morphologically cryptic species. The marine planktonic chaetognath Sagitta setosa Müller has a discontinuous geographic distribution over the continental shelf in the northeastern Atlantic, Mediterranean S...
The Qaidam Basin in the core area of arid Inner Asia has been considered undergoing continuous aridification over Cenozoic. However, is marked with expanded lacustrine sedimentation during Oligocene, which contrasts fluvial or deltaic facies stratigraphically below (Eocene) and above (Miocene-present). Oligocene expansion challenges idea persistent aridification. To solve conundrum, we reconstr...
