E volution has done wonders with mass extinctions. Organic diversity has rebuilt itself at least five times during the history of life on Earth, fashioning novelty from the organic remnants of each catastrophe (1). Modern biodiversity arose from a global extinction event at the end of the Cretaceous period (the ‘‘K-T’’ extinction) that probably was caused by an asteroid or comet impact. This pe...

Despite the extensive fossil record of higher crabs (Eubrachyura) from Late Cretaceous and Cenozoic rocks worldwide, their Early Cretaceous occurrences are scarce and fragmentary, obscuring our understanding of their early evolution. Until now, representatives of only two families of eubrachyuran-like crabs were known from the Early Cretaceous: Componocancridae and Tepexicarcinidae fam. nov., b...

Modern amphibians (lissamphibians) are highly sensitive indicators of environmental disturbance. As such, fossil lissamphibians are an excellent model for testing causal hypotheses of the Cretaceous-Paleogene mass extinction and secondary effects of Deccan volcanism and a bolide impact (e.g., acid rain). We quantitatively analyzed high-resolution temporal changes in diversity and community stru...

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...

Detrital zircon U-Pb ages for 30 Late Jurassic and Cretaceous sandstones from the Eastern Province of eastern New Zealand, combined with previously-published geochronological and palaeontological data, constrain the time of deposition in the Pahau and Waioeka terranes of the Cretaceous accretionary margin of Zealandia, and their adjacent cover strata. The zircon age patterns also constrain poss...

A synthesis of our current knowledge erymoid lobsters is presented. The superfamily Erymoidea includes two families, Erymidae Van Straelen, 1925 and Enoploclytiidae Devillez, Charbonnier & Barriel, 2019, together encompassing 81 species within six genera. Our examination the palaeobiodiversity this group its evolution has revealed some variations through Mesozoic with three important peaks, at ...

The Grajcarek Unit of the Pieniny Klippen Belt (PKB), at boundary between Central (Inner) and Outer Carpathians, resulted from convergence ALCAPA (the Alps–Carpathians–Pannonia) block European plate. strongly deformed slices consist Jurassic–Cretaceous sedimentary rocks associated with Late Cretaceous–Middle Palaeocene synorogenic wild-flysch, breccias olistoliths. Maximum burial temperatures d...

Commercial hydrocarbon discoveries in the Cretaceous of the southern Persian Gulf basin provide direct evidence that there is an effective petroleum system associated with the Cretaceous series. The revised models of thermal maturity in this region are needed to investigate lateral and stratigraphic variations of thermal maturity, which have not so far been addressed in detail for this part of ...

The intrusive age ranges of Linglong, Guojialing, Weideshan, and Laoshan granites in the Jiaodong Peninsula are 155–154 Ma, 131–130 118–111 116 respectively. Together with Shidao granite (227–200 Ma), five phases magmatism can be classified by time, all which have different degrees gold polymetallic mineralization. type evolved from A–, S–type to I–, A–type Late Triassic Early Cretaceous, thus ...
