The beginnings of the Sargasso assemblage in the Tethys
Abstract An assemblage of organisms, here termed “quasi-Sargasso”, occurs in the Oligocene menilite beds of the Carpathian flysch. It is suggested that this assemblage migrated into the Atlantic Ocean, probably during the Miocene. Its further evolution, which gave rise to the present-day Sargasso assemblage, took place in the middle Atlantic area.
