Paleontological studies allow a subdivision of the Kirchberg beds (Ottnangian, Lower Miocene) in the vicinity of Leipheim on the Danube. The succession corresponds to horizons 2b to 8 at the type-locality Illerkirchberg. A new charophyte species(Chara venusta n. sp.) is described from horizon 2b, and its relation to theChara notata/Ch. microcera- group is discussed. 相似文献
