Middle Jurassic theropods have a scanty record worldwide, especially from Gondwana. In India, where are particularly rare and only represented by few isolated teeth some badly preserved bones, there is currently no of the western India. Here we report first theropod dental material marine carbonate rocks Jaisalmer Basin, north-western The specimen consists an incomplete shed tooth crown recover...

The Kyunetsa section, 2.5 km west of Kosharevo, exposes mainly pelagic Upper Cretaceous marly limestones and marls the Srednogorie Zone, part intermediate Balkanides in Bulgaria. Melove Formation Coniacian to early Campanian age involves a prominent Santonian-Campanian boundary interval grey reddish sediments, including CORBs (Cretaceous Oceanic Red Beds). base can be discerned bed 7c by first ...

Abstract. Permian–Triassic boundary sections at Baghuk Mountain (Central Iran) are investigated with respect to their lithological succession, biostratigraphy (particularly conodonts, nautiloids and ammonoids) as well chemostratigraphy (carbon isotopes). The rock successions consist of the Late Permian Hambast Formation, youngest Member (new name for “Boundary Clay”) Early Triassic Claraia beds...

The Sistan orogen (Eastern Iran) separates the Afghan and Lut continental blocks stretches along ?700 km from north to south, at a high angle with respect other, dominantly E-W trending Alpine-Himalayan orogens. This study reappraises tectono-metamorphic evolution of northern part orogen, as well its significance within Neotethyan realm. Detailed inspection ophiolite indicates that Ocean was sl...

The Paleogene evolution of the NW margin African Plate (Western External Rif Zone) was studied by means multidisciplinary analyses twenty-one stratigraphic logs, including tectofacies recognition, petro-mineralogical results, and thicknesses analysis. Four intervals were recognized separated three unconformities coarsely aligned with Cretaceous–Paleogene, Eocene–Oligocene Oligocene–Miocene boun...

Petrological, geochemical, and biostratigraphical investigations have been conducted on seventy-nine samples from four selected sections in Jordan to understand the factors that influenced enrichment deposition of massive phosphorite deposits. The calcareous nannofossil marker species Broisonia parca constrica Reticulofenestra bisecta, assigned 1 2 (Hawar Al Dhahikiyya), were indicative Campani...
