VISEAN CORALS OF THE KIYASAR AREA, SOUTH OF SARI, NORTHERN IRAN

Corals from the middle part of the Mobarak Formation, exposed in the Kiyasar area of northern Iran, were examined for descriptions, age determination and indications of the paleoenvironment. New genera for the families Adamanophyllidae and Clisiophyllidae/ Amygdalophyllinae were established and three new species were described for the Bifossularia, Clisiophyllum and Spirophyllum genera. The age of studied corals is generally consistent with the early-middle Visean as previously was determined based on foraminifera. The absence of colonial rugose and syringoporid is a notable feature of these coral communities.
