A Survey on the condition of Micro Facies , Sedimentary Environment and the Cretaceous Deposits ( With Particular Reference to Central Iran )
Micro continent of central Iran is a part of middle Iran that is bounded with ophiolithic suture zones in Sistan, Naiin, Baft, Doruneh fault and Kashmar – Sabzevar ophiolites and is classifiable into Lut block, Shotori upland, Tabas subduction, Kalmard upland, Posht Badam block, Biaze Bardsir basin and Yazd block by means of long faults which are dextral strike – slip faults and have westwards inclination. In many regions of Iran, except to Zagros, in approximate boundary of early and late Cretaceous, it is observed evidences of tectonic events which are mainly as land generating and can be compared with worldwide Austrian event, in everywhere in Iran except to rare cases (east of Tehran and Yazd). Upper Cretaceous beds in Iran do not have identical facial characteristics and it seems that in contrast to equal sedimentary condition in early Cretaceous, sedimentary basins in upper Cretaceous have been separated from each other and special condition has been dominated in each basin. As a result of that, lithostratigraphic units except to Zagros and Kopet Dagh have not been named and or have local names in upper Cretaceous of Iran. This article is an overview of the condition of Micro-facies, sedimentary environment and the Cretaceous deposits in central Iran. [Mehran Arian, Hamideh Noroozpour.

Albian decapod Crustacea from Southeast Isfahan, Central Iran- Kolah-Qazi area
The first record for Cretaceous (Albian) crustaceans from Southeast Isfahan, Central Iran-Kolah-Qazi area is provided based on presence of the raninid crab Notopocorystes xizangensis Wang, 1981, as well as callianassoid remains and articles of ?Hoploparia sp. Details of the stratigraphic section were material was collected are provied, as well as a brief review on the previous geologic reports of the study area. Abstract
Systematics Of The Raninidae (Crustacea : Decapoda : Brachyura), With Accounts Of Three New Genera And Two New Species
—Reexamination of the Raninidae reveals revised relationships of raninid genera, both fossil and Recent. Symethis Weber is removed from the Raninidae and placed in the newly erected Symethidae under the Raninoidea. One subfamily is reestablished, Palaeocorystinae, and several subgenera are elevated to generic status: Notopocorystes McCoy, Eucorystes Bell, and Cretacoranina Mertin within the Palaeocorystinae. Lysirude Goeke, within the Lyreidinae, is distinguished as a discrete genus rather than as a subgenus of Lyreidus De Haan. Additionally, three new genera are described: Macroacaena, within the Lyreidinae and Carinaranina and Quasilaeviranina within the Raninoidinae. Two new raninid species, Laeviranina goedertorum and Carinaranina marionae, from the Eocene Hoko River Formation of Washington, U.S.A., are established. Descriptions of three species previously described by Rathbun are emended based upon new fossil material: Carinaranina willapensis (Rathbun) new combination, Laeviranina lewisanus (Rathbun) and L. vaderensis (Rathbun). The description of Eumorphocorystes sculptus Binkhorst is emend-
