The Romanium (also Ruman, Roumanien) is a regional chronostratigraphic stage in the central Paratethys area, which is correlated with the global stages of the Piacenzian ( Neogene ) and the Gelasian ( Quaternary ).

Naming

The stage is named after the Eastern European state Romania . It was introduced into literature in 1932 by Karl Krejci-Graf .

definition

The lower limit of the Romanium is defined by the first occurrence of the snail species Viviparus bifarcinatus . The stage itself is characterized by Süßwasserfaunen: Dreissena polymorpha (Pallas), Pseudohyriopsis Problematica (Cobalcescu), UAC sp. Pisidium sp. Theodoxus licherdopoli scriptus (Stefanescu) Valvata (Valvata) sulekiana (Brusina) Bulimus (Bulimus) vukotinovici ( Brusina), Melanopsis (Melanopsis) pterochilla pterochilla (Brusina), Lithoglyphus sp. and Viviparus bifarcinatus (Bielz).
