a detailed study of the lower cretaceous dasyclad algae of the shahkuh formation was done in the chahpalang stratigraphic section (its name comes from the mountain in studied area). according to the study of the 101 thin sections, for the first time, we recognized 7 genus and 8 species of dasyclad algae from shah kuh formation in chah palang section including angioporella cf. fouryae, griphopor...

The Cretaceous family Spathiopterygidae (Hymenoptera: Diaprioidea), containing five species in four genera, showed a wide distribution from the upper Barremian to Turonian. We describe two new representatives of Albian San Just outcrop eastern Iberian Peninsula that correspond Diameneura marveni gen. et sp. nov. Santer and Álvarez-Parra female member Mymaropsis turolensis Engel Ortega-Blanco, 2...

We present a new tracksite with multiple dinosaur tracks from the lowermost Barremian (Lower Cretaceous) of Cape Espichel (Sesimbra, Portugal). The are localized on three beds top carbonate Areia do Mastro Formation. Those bioclastic, nodular limestones were deposited in very shallow subtidal-intertidal, restricted lagoon environment. track surfaces dinoturbated, substantial number tracks. Seve...

The species Coniopteris laciniata and Sphenopteris wonnacottii are heterophyllous ferns recovered from two Spanish Barremian localities, Las Hoyas El Montsec respectively. similarities between these species, observed in a study of total 66 hand specimens both indicate that they conspecific. Following the rule priority botanical nomenclature, because there doubts about assignment this to higher ...

The Tirgan Formation (Barremian – Aptian) is exposed in the Kopet Dagh in northeast Iran. One stratigraphic section in Zavin was measured with a thickness of 110 meters. This Formation in section consists of three parts (including lower carbonate, limy shale – marl and upper carbonate rocks). Based on the study of 94 thin sections, 10 carbonate and 2 siliciclastic lithofacies have been identifi...

For the microbiostratigraphical studies, a stratigraphical section (named Dareh-Goshayesh) has been selected in southeast of Maragheh, Northwestern Iran. The thickness of successions in the selected stratigraphic section is measured about 223.6 m. The mentioned studied stratigraphic section is composed of two clastic and carbonate units. This succession unconformably overlies the Lar Formation ...
