Abstract
ABSTRACT. This paper is the first illustration of Late Ordovician- Early Silurian, Early Devonian and Middle Carboniferous- Early Permian calcareous marine algae from Uzbekistan. Chlorophyta are very prolific and diverse. They are associated with some cyanophytes and rhodophytes. Taxa have been previously recorded. The flora is typically Central Tethyan and compares easily with that of Central and Southern Urals. Most algae have a wide stratigraphie range, are facies sensitive, and thus have only local age significance.
