Abstract Ophiolitic mélanges in Anatolia represent Mesozoic subduction-accretion complexes, which are unusually poor land-derived coarse-clastic rocks. A segment of the ophiolitic mélange Beynam region south Ankara was studied. The consists three accretionary units (AUs), distinguished by lithology, structure, age and geochemistry. At base there is a serpentinite mélange, overlain semi-intact U...

statistical studies on palynology contents of late cretaceous to paleocene age gurpi formation in a surface section in zagros basin,sw iran indicate changes in abundance, species diversity, ratio of spiniferites to cyclonephelium (s/c), palynological marine index(pmi) values and organic facies. these palynological variations clearly reflect fluctuations in relative sea-level and depositionalenv...

Abstract The Upper Cretaceous–Pliocene strata of New Zealand record ~100 m.y. Zealandia's evolution, including development the Hikurangi convergent margin and Alpine transform plate boundary. A comprehensive, new detrital zircon U-Pb data set (8315 analyses from 61 samples) was generated along a ~700 km transect East Coast Basin Zealand. Age distributions were analyzed interpreted in terms publ...

We studied Upper Cretaceous and Lower Paleogene benthic foraminifera from the Agost section (southeastern Spain) to infer paleobathymetrical changes and paleoenvironmental turnover across the Cretaceous/Paleogene (K/P) transition. Benthic foraminifera indicate uppermost bathyal depths at Agost during the Abathomphalus mayaroensis Biochron (from about 400 kyr before the K/P boundary) through the...

Australian dinosaurs have played a rare but controversial role in the debate surrounding the effect of Gondwanan break-up on Cretaceous dinosaur distribution. Major spatiotemporal gaps in the Gondwanan Cretaceous fossil record, coupled with taxon incompleteness, have hindered research on this effect, especially in Australia. Here we report on two new sauropod specimens from the early Late Creta...
