Calcareous algae from the Jurassic and Cretaceous of Lebanon

Carbonate strata of Middle Jurassic to Late Cretaceous age, sampled from outcrops in Mount Lebanon, have been found to contain a wide variety of marine calcareous algae. These consist predominantly of green algae (Chlorophyceae), which are most numerous in the Lower Cretaceous limestones. Species here identified as occurring in Lebanon include cosmopolitan representatives of the families Dasycladaceae and Codiaceae of the green algae, and Corallinaceae and Solenoporaceae of the red algae. Each algal species is apparently confined to a certain stratigraphic interval and a certain paleoenvironment.
