| Abstract |
A new diatom species, Entogonia briggeri n. sp. is described from Middle Miocene sediments of Romania. Detailed morphological investigations are presented using scanning electron microscopy with particular attention for internal coil system. This new species is compared with two related taxa E. formosa (Truan & Witt) Bergon described from the Middle Eocene sediments from Conset, Barbados and E. hungarica Holmes & Brigger 1979 from the Miocene sediments from Szurdokpüspöki, Hungary. This new species allows extending occurrences area of the genus and its time span distribution, as well as some remarks on some morphological elements of the genus. |
