The Palaeogeography of Lake Pannon During Deposition of the Congeria rhomboidea Beds
نویسنده
چکیده
Lake Pannon covered the area of the Pannonian Basin during the Late Miocene. Because of its wide-range distribution, economic importance and unique, mostly “caspi-brackish” endemic biota, its lacustrine deposits have attracted much scientific attention in the past hundred years. According to the latest stratigraphic division accepted for the area and bioprovince of the Western or Central Paratethys these deposits belong to the PannonThe Palaeogeography of Lake Pannon During Deposition of the Congeria rhomboidea Beds

Sub-Decadal Resolution in Sediments of Late Miocene Lake Pannon Reveals Speciation of Cyprideis (Crustacea, Ostracoda)
Late Miocene "Lake Pannon" (~11.3 Ma) was a remnant of the Central Paratethyan Sea. Successive freshening and constantly changing environmental conditions, like oxygenation, nutrition and substrate led to a well-documented radiation in molluscs and ostracods. Among ostracods (small crustaceans), Cyprideis is one of the most common genera in "Lake Pannon", as well as in several other ancient lak...
