Decapod crustaceans from the lower Miocene Qom Formation of the Isfahan area, Central Iran

From the lower Miocene (Burdigalian) of the Qom Formation, exposed in three sections (Kuh-e-Donbeh, Bagher-Abad, and Vartun) in Central Iran, a deca-pod crustacean assemblage is described. The specimens exhibit two modes of preservation: carapaces (either isolated or with attached appendages) and isolated cheliped elements. All studied specimens are fractured and/or eroded. Based on this moderately preserved material, three brachyuran crab taxa are identified, including Mursia cf. lienharti (Bachmayer, 1962), Palaeocarpilius rugifer Stoliczka, 1871, and Necronectes sp. The occurrence of P. rugifer represents the youngest confirmed occurrence of the species, whereas other two taxa represent the first confirmed Iranian occurrences of respec-tive genera. This report enriches our knowledge on Miocene decapod assemblages of Iran, and thus helping to better understand the decapod migratory patterns along the Tethyan Sea-way.

One New Species

A study of bryozoans and brachiopods from the Varton, Zefreh and Kuh-e-Charkheh sections from the Esfahan-Sirjan fore-arc basin of the Qom Formation of Central Iran has yielded 30 bryozoan taxa, including one new species Gigantopora vartonensis, and six brachiopod species. Both assemblages co-occur with large oyster shells with some of the ventral valves of brachiopods directly attached to their shells. The paleoenvironment is interpreted as an oyster bank ('oyster reef') in shallow, tropical-subtropical marine waters, producing cryptic habitats for other groups of organisms.
