During the mid-Piacenzian, Nordic Seas sea surface temperatures (SSTs) were higher than today. While SSTs provide crucial climatic information, on their own they do not allow a reconstruction of potential underlying changes in water masses and currents. A new dinoflagellate cyst record for Ocean Drilling Program (ODP) Site 642 is presented to evaluate changes in northward heat transport via the Norwegian Atlantic Current (NwAC) between 3.320 and 3.137Ma. The record is compared with vegetation and SST reconstructions from Site 642 and SSTs from Iceland Sea ODP Site 907 to identify links between SSTs, ocean currents, and vegetation changes. The dinocyst record shows that strong Atlantic water influence via the NwAC corresponds to higher-than-present SSTs and... |

A description is given of the fossil small mammal remains that were found during dredging activities in the Oosterschelde estuary, the Netherlands. The following taxa are encountered in the samples: Mimomys pliocaenicus, Mimomys reidi, Mimomys tigliensis, Mimomys newtoni, Trogontherium sp., Beremendia fissidens, Sorex (Drepanosorex) praearaneaus, and Galemys kormosi. The find of one m1 of Microtus oeconomus is considered to be a contamination. The fauna is of Late Pliocene age, and may appear slightly older than the classic Tegelen fauna. In terms of mammal zonation, we consider the age to be MN17. |
