Article: Transported algae as indicators of different marine habitats in the English Middle Jurassic

A microflora of red, green, and blue-green algae is recorded from the Middle Jurassic Great Oolite (Bathonian) White Limestone Division, near Cirencester, Gloucestershire. New genera described are Apophoretella (Myxophyceae) and Dobunniella (Chlorophyceae, Dasycladaceae). The fossils are not found where they grew: their probable original environments are discussed, and these suggest conditions like those of the present-day Great Bahama Bank.
