Did Late Cretaceous cooling trigger the Campanian–Maastrichtian Boundary Event?
The Campanian–Maastrichtian (83–66 Ma) was a period of global climate cooling, featuring significant negative carbon-isotope (δ13C) anomalies, such as the Late Campanian Event (LCE) and the Campanian–Maastrichtian Boundary Event (CMBE). A variety of factors, including changes in temperature, oceanic circulation and gateway opening, have been invoked to explain these δ13C perturbations, but no p...
متن کاملCampanian and Maastrichtian Biostratigraphy and Paleoenvironment in Jorband Section, North of Iran
The study of planktonic foraminifera in Jorband section reveals two major events in Campanian- Maastrichtian boundary and early-late Maastrichtian bio-diversification. In this study, occurrence and species richness of planktonic foraminifera in Jorband area show the warm marine environment dominant during early to late Campanian and it could be correlating by tropical and subtropical biozones. ...
متن کاملLate Maastrichtian pterosaurs from North Africa and mass extinction of Pterosauria at the Cretaceous-Paleogene boundary
Pterosaurs were the first vertebrates to evolve powered flight and the largest animals to ever take wing. The pterosaurs persisted for over 150 million years before disappearing at the end of the Cretaceous, but the patterns of and processes driving their extinction remain unclear. Only a single family, Azhdarchidae, is definitively known from the late Maastrichtian, suggesting a gradual declin...
متن کاملSpecies Richness and Evidence of Random Patterns in Assemblages of South American Titanosauria during the Late Cretaceous (Campanian–Maastrichtian)
The Titanosauria were much diversified during the Late Cretaceous, but paleobiological information concerning these sauropods continues to be scarce and no studies have been conducted utilizing modern methods of community analysis to infer possible structural patterns of extinct assemblages. The present study sought to estimate species richness and to investigate the existence of structures in ...
متن کاملTrace Fossils from the Campanian - Maastrichtian Enugu Formation of the Anambra Basin, South-eastern Nigeria: Implications for Paleoenvironmental Interpretation
The Enugu Formation is a member of the Nkporo Group, and forms part of the basal stratigraphic unit of the Anambra Basin in south-eastern Nigeria. The Enugu Formation has been the subject of many studies concerning stratigraphy [1], depositional environments [2; Onuigbo et al. [3], organic geochemistry [4-6], paleoecology [7], palynology [7-9] and ichnology [10]. Nwajide & Reijers [2] were the ...
