Algae (Dasycladales) from the Upper Triassic Nayband Formation (northeast Iran)

Dasycladales are relatively abundant in the bedded limestones of the Bidestan and Howz-e Khan members of the Late Triassic Nayband Formation in central Iran. In a locality south of the town of Naybandan (northwest of Dig-e Rostam), several Rhaetian dasycladacean algae were found in thin sections. The following taxa are described: Diplopora phanerospora Pia, Naybandoporella rhaetica nov. gen. nov. sp., Naybandoporella cf. rhaetica. The species Probolocuspis sarmeikensis Senowbari-Daryan is replaced and attributed to the genus Naybandoporella. The microfacies characteristics of the limestones as well as the associated organisms are mentioned.
