    Summary
    Early Cretaceous shallow carbonate deposits in the Zagros fold-thrust belt, SW Iran, are being studied for a high-resolution stratigraphic pattern and detailed environmental analysis. These carbonates contain diversified assemblages of dasycladalean algae, indicating shallow subtidal depositional environments. A new dasycladalean alga and interesting marker is described as Mizzia zagarthica sp. nov. from Late Berriasian-Early Valanginian deposits of the Fahliyan Formation. Focusing on the presence of reproductive organs (cysts) in the laterals, the genus, which so far has been reported only from the Permian, is emended. Based on newly described material from Greece and New Mexico, the genus Mizzia is re-assessed. The paper also includes a critical revision of the genera Neomizzia and Banciloporella.
