an abrupt global warming event has been recorded in many parts of the world in sediments of latest maastrichtian age between 65.45-65.10 ma. this warm event was documented here at a section near ziyarat-kola in central alborz based on analysis of planktonic foraminifera. an unusual abundance of normally large-size species such as globotruncana arca, globigerinelloides subcarinatus, pseudoguembe...

The Campanian–Paleocene Jaworzynka Formation, a part of the Magura Nappe succession in Polish Outer Carpathians, is described terms its detailed litho- and biostratigraphy. formation stretches along marginal Siary Unit, from stratotype area Silesian Beskid Mts up to Mszana Dolna Wyspowy Mts. Its equivalent Moravskoslezske Beskydy the Czech Republic Solaň Formation. In area, displays complex str...

The Peirópolis paleontological site (Late Cretaceous, Maastrichtian) in Minas Gerais State, Brazil yielded an important assemblage of fossil vertebrates. The typical occurrence of South American widespread taxa in Peirópolis is important for correlation between the Brazilian Bauru Basin and Argentinean Late Cretaceous basins. The fishes, turtles, anuran, crocodilians and dinosaurs known from Pe...

The occurrence of a large number of fossil woods having resemblance in anatomical features with the modern palm genus, Phoenix L in Deccan Intertrappean fossil flora of Maastrichtian-Danian age (i. e. Late Cretaceous and Earliest Tertiary (65-67 my)) indicates the most primitive record of date palm. Present discovery of biocompounds from fossil wood of Phoenix collected from Deccan Intertrappea...

Dakotaraptor steini is a recently described dromaeosaurid dinosaur from the Upper Cretaceous (Maastrichtian) Hell Creek Formation of South Dakota. Included within the D. steini hypodigm are three elements originally identified as furculae, one of which was made part of the holotype specimen. We show that the elements described as D. steini 'furculae' are not theropod dinosaur furculae, but are ...

Abstract Besides nitrate deposits located in the Atacama Desert of Chile and Mojave California, present work documents, for first time, occurrence potassium as oval-suboval-shaped aggregations associated with Late Maastrichtian-Early Paleocene Dakhla Shale Paleocene-Early Eocene Esna encountered northeastern part Kharga Oasis, particularly at G. Um El-Ghanayem Ghaneima. Consequently, integrated...

In the previous paper, geological ages of Late Cretaceous, Paleocene, late Middle to Eocene, Oligocene and early Early Miocene were confirmed at first time, based on occurrences both age diagnostic larger foraminifera associated planktonic foraminifera, from Sashida Limestone included basalt pebbles, Sashida, Kamo-Gun, south Izu Peninsula. Therefore, was made up clastic carbonate rocks various ...

The South-Pyrenean Basin (northeastern Spain) has yielded a rich and diverse record of Upper Cretaceous (uppermost Campanian−uppermost Maastrichtian) vertebrate fossils, including the remains some last European dinosaurs prior to Cretaceous-Paleogene (K-Pg) extinction event. In this work, we update characterize fossil Arén Sandstone Tremp formations in Western Syncline, which is located Aragone...
