High-precision U-Pb ages in the early Tithonian to early Berriasian and implications for the numerical age of the Jurassic-Cretaceous boundary [PDF]
, 2019 The numerical age of the Jurassic-Cretaceous boundary has been controversial and difficult to determine. In this study, we present high-precision U-Pb geochronological data around the Jurassic-Cretaceous boundary in two distinct sections from different ...

Migration Routes of the Aptian to Turonian Ostracod Assemblages from North Africa and the Middle East [PDF]
Paleontology Journal, 2014 Quantitative paleobiogeography is a powerful tool for detecting the migration routes of microfossils. This is factual and applicable when we select appropriate analyses for proper problems in the following manner. The quantitative study of 43 selected ostracod species (total of 136 species) from 11 countries of North Africa and the Middle East led to ...

Environmental changes during marl-limestone formation: evidence from the Gargasian (Middle Aptian) of La Marcouline Quarry (Cassis, SE France) [PDF]
Carnets de géologie (Notebooks on geology), 2007 Limestone-marl alternations are usually interpreted to reflect cyclic paleoenvironmental fluctuations linked to Milankovitch-scale climate variations. However, the impact of diagenesis on lithological differentiation can be overprinted on the primary signal.In order to evaluate environmental variations during the deposition of the Gargasian hemipelagic

Cretaceous Research, 2020 Abstract A low relief middle Aptian (Gargasian) reef built by platy corals is described from the Lower Cretaceous succession of the Resiţa–Moldova Noua zone (Southern Carpathians, SW Romania). Two coral-bearing units, 16–17 and 38–42 m thick, discontinuously cover ca. 1100 m. This is an unusually thick fossil reef to be built by platy corals.

Response and Recovery of the Comanche Carbonate Platform Surrounding Multiple Cretaceous Oceanic Anoxic Events, Northern Gulf of Mexico [PDF]
, 2015 The ubiquity of carbonate platforms throughout the Cretaceous Period is recognized as a product of high eustatic sea-level and a distinct climatic optimum induced by rapid sea-floor spreading and elevated levels of atmospheric carbon-dioxide.
