the Pliozän is an earth-history epoch of the period Neogen. It began 5.33 million years ago and ended forwards1,8 million years, with the beginning of the Pleistozän, see also geological time scale (table).
Until 2004 the Pliozän was regarded as a last epoch of the Tertiary period before the quart acre, is pulled today the border between Tertiary period and quart acre toward end of the Pliozäns, thus before 2,6Millions years, with the beginning of the Gelasiums. Before the Pliozän the Miozän lies. After it the Pleistozän , the ice age, with a change from warm and cold times in the Holozän , follows the geological present.
Table of contents
the Pliozän within the geological time scale into three sections one divides:
- Gelasium (2.588 to 1.806 million years today ago)
- Piacenzium (3.600 - 2.588 million years today ago)
- Zancleum (5.332 - 3.600 million years before today)
the climate in the Pliozän was still warm in Europe, but announced a gradual cooling the forthcoming ice age . With the freezing up of the pole caps the ice age age quart acre in the Gelasium, the last stage of the Pliozäns , which persists until today, began.
the land bridge between north - and South America began itself to form, which stronger effects on the propagation of many animal kinds, e.g. the trunk animals of Africa over Asia to north and South America had. The South American animal world, itself in the isolation independentlyhad developed, changed. In Europe the Deinotherien became extinct, in Africa only in the lower Pleistozän in the middle Pliozän.
In the Neogen (particularly in the Miozän) the alpidische Gebirgsbildung running off of the alps, Karpaten and other mountains in Eurasien (Himalaya) was stopped nearly(there are small elevations until today). The large sediment masses in of Europe levels and tectonic basins were only covered in the Pliozän by a relatively thin formation, before the glaciers and crushed stone of the first large cold times coined/shaped the today's landscapes.
