Three well - known source rocks of the Zagros basin and the Persian Gulf are Mesozoic in age.The Jurassic Sargelu, Albian Kazhdumi and Neocomian-Coniacian Garau formations have charged the Cretaceous reservoirs of this area. The northwest part of the Persian Gulf is strongly influenced by two major N-S trending paleohighs (Hendijan- Bahregansar-Regesafid-Izeh and Kharge- Mish) and surrounding p...
Brachiopod faunas from the Aptian- Cenomanian Vezk section in southwesternIran comprise ten species in six genera, namely Sellithyris cenomanensis, Sellithyris tornacensis, Sellithyris phaseolina, Phaseolina phaseolina, Tropeothyris sp., Concinnithyris subundata, Kingena arenosa, Cyclothyris difformis, Cyclothyris sp. and Cyclothyris compressa. All species are recorded for the first time from t...
A new palaeocorystid crab, Joeranina houssineaui n. sp., is described from upper Cenomanian strata in southwest France, Being apparently derived from J. broderipii, the new species inhabited a sandier substrate environment than its predecessor. The incomplete holotype reveals portions of the internal pleurites, which are rarely seen in extinct crabs.
A new species of the extinct genus Serphites Brues (Proctotrupomorpha: Bipetiolarida: Serphitidae) is described from two individuals preserved in Late Cretaceous (Cenomanian to Santonian) amber from Vendée, northwestern France. Serphites fannyae n. sp., is distinguished from its congeners and brief comments are made on the significance of finding a serphitid wasp in Vendean amber as well as pot...
Peneroplis turonicus Said and Kenawy is a poorly known benthic foraminifer that was originally described based on isolated specimens from the Upper Cretaceous of Egypt. Specimens Cenomanian Sarvak Formation Iran indicate presence finely agglutinated test wall displaying pseudo-keriothecal texture, therefore, excluding this taxon porcelaneous Miliolida, namely family Peneroplidae. Based morpholo...
A new braconid wasp from the Upper Cretaceous (Cenomanian) amber of the Hukawng Valley in Kachin State, Myanmar is described and figured from a unique female. Seneciobracon novalatus Engel & Huang, gen. et sp. n., is placed in a distinct subfamily, Seneciobraconinae Engel & Huang, subfam. n., owing to the presence of a unique combination of primitive protorhyssaline-like traits, with an otherwi...

The uppermost Albian and lowermost Cenomanian succession at Abouda Plage, north of Agadir, in the Agadir Basin, western Morocco, is described detail, ammonites, microcrinoids planktonic foraminifera are recorded illustrated. lower part Ait Lamine Formation yields ammonites indicative the Pervinquieria (Subschloenbachia) rostrata P. ( S. ) perinflata ammonite zones, Thalmanninella appenninica f...
A new species of fossil ray spider, Baalzebub? mesozoicum n. sp. (Araneae: Theridiosomatidae), is described from Mesozoic amber from the Cretaceous (Middle Cenomanian to Early Santonian) deposits of La Garnache, Vendée, NW France. The palpal structures, especially the highly sclerotized claw-shaped retrolateral ‘paracymbium’ originating as an outgrowth of the cymbium basally and the basal cymbi...
چکیده: به منظور بررسی سنگ- زیست چینه نگاری، ریزرخساره ها، محیط رسوبی و چینه نگاری سکانسی سازند سروک در شمال شرق گچساران یک برش چینه ای در تنگ گرگدار مورد مطالعه قرار گرفته است. این برش به ضخامت 450 متر و عمدتاً از لایه های آهکی متوسط تا ضخیم لایه و توده ای تشکیل شده است. در این برش، مرز بین سازند سروک و سازند زیرین آن (کژدمی) به صورت پیوسته و مرز آن با سازند بالایی(گورپی) ناپیوسته می باشد. بر ا...
