Two stratigraphic sections (Kuh-e-Rahmat and Kuh-e-Sabz) of Upper Cretaceous strata in the Interior Fars region (SW of Iran) were selected. Lower Cretaceous succession of Kuh-e-Rahmat was consisted of Dariyan, Kazhdumi Sarvak and Ilam Formations. The lower contact of the Sarvak Formation with Kazhdumi Formation is described as a transitional type whereas the upper contact of Sarvak Formation wa...

An organic geochemical investigation combined with sequence stratigraphy was performed in the Ceará Basin, an offshore basin located Northeastern Brazil. The information available from 30 well logs (gamma-ray, resistivity, density), besides (TOC, and pyrolysis indexes) isotopic (?13C) data, aided preparation of a dataset for this study. application sequence-stratigraphic methods helped classify...

The first megaspores recovered from Ukrainian Lower Cretaceous strata are described and illustrated by reflected light scanning electron micrography. Four lycopsid megaspore taxa identified in core samples north of Kherson (Khersons'ka Oblast), the Black Sea Basin, southern Ukraine. Miospore assemblages same reveal a slightly higher diversity microspores and, conjunction with previous foraminif...

The Partizansk and Razdolnaya coal basins of Primorye, Far East Russia, contain diverse early angiosperm fossils (pollen, leaves, fruits). In this paper, we revise the previous data on angiosperms region summarize results our latest research. Age plant-bearing deposits was clarified using isotopic U-Th-Pb LA-ICP-MS U-Pb ID-TIMS methods. upper part Lipovtsy Formation is 118 ± 1.4 Ma, which corre...

Early Cretaceous body and trace fossils in Victoria, Australia, establish the oldest known presence of parastacid crayfish (Decapoda: Astacidea, Parastacoidea) in freshwater environments of Australia, and the oldest known crayfish in Gondwana. Parastacid body fossils, comprised of a partial abdomen (Palaeoechinastacus australianus, gen. et sp. nov.) and two chelae, are from a fluvial deposit in...

The record of Gondwanan Mesozoic lizards is very poor. Among the few species described for this region there is Tijubina pontei, an Early Cretaceous lizard from the Crato Formation (late Aptian) of northeast Brazil. Its description is very brief and lacks most of its diagnostic characters and clear delimitation from other lizard species. Here, a full redescription of the holotype is provided. T...

The Aptian Jiufotang Formation of northeast China is a Konservat Lagerstätte particularly rich in pterosaurs, notably azhdarchoids. Here we describe a new genus and species of toothed pteranodontoid pterosaur, Ikrandraco avatar gen. et sp. nov., based on two laterally flattened specimens. Ikrandraco avatar is diagnosed by a suite of features, including a very low and elongate skull, strongly in...
