Mesozoic and Cenozoic diktyogenese in the Lower Yangtze region

Shiyou shiyan dizhi, 2020
Three stages of metamorphic tectonic movements took place in the Lower Yangtze region due to the joint action of the Tethys and the Pacific plates from the Middle/Late Triassic to the Early/Middle Jurassic, the Late Jurassic to the Early Cretaceous, and ...

Neotethyan Ankara Melange, central Turkey: Formation by accretion of seamounts and supra-subduction zone ophiolites in an oceanic fore-arc setting

Journal of Asian Earth Sciences: X, 2023
The Neotethyan Ankara Melange is a global reference for oceanic accretionary processes preserved in a collisional orogen. Here we show, based on eight representative outcrops around Ankara, that the melange encompasses stratigraphically coherent volcanic-

Island life in the Cretaceous - faunal composition, biogeography, evolution, and extinction of land-living vertebrates on the Late Cretaceous European archipelago

ZooKeys, 2015
The Late Cretaceous was a time of tremendous global change, as the final stages of the Age of Dinosaurs were shaped by climate and sea level fluctuations and witness to marked paleogeographic and faunal changes, before the end-Cretaceous bolide impact ...

The First Fossil Coelacanth from Thailand

Diversity, 2023
Mawsoniidae is a family of coelacanths restricted to the Mesozoic. During the Cretaceous, mawsoniids were mainly represented by the Mawsonia/Axelrodichthy complex, long known to be from western Gondwana only (South America and Africa).

LATE CREATACEOUS-CENOZOIC SEDIMENTS OF THE BAIKAL RIFT BASIN AND CHANGING NATURAL CONDITIONS

Геодинамика и тектонофизика, 2015
The late Cretaceous-Cenozoic sediments of fossil soils and weathering crusts of the Baikal rift have been subject to long-term studies. Based on our research results, it is possible to distinguish the following litho-stratigraphic complexes which are ...

A Late Cretaceous Lonchodectid? [PDF]

, 2019
Abstract A pterosaur ulnar specimen (NZMS CD 467) from the Mangahouanga Stream of New Zealand’s North Island has been first described by Wiffen et al 1988. Assumed to belong to a “Santanadactylus- like” pterosaur, this taxon has not since been extensively described, with only a few ...

Contrasting characteristics observed between the early and late Cretaceous periods: Evidences from geochemical and isotopic studies of clastic rocks from the Tethys Himalaya, India

Journal of Asian Earth Sciences: X
This study uses a multi-proxy approach on Cretaceous shales (consisting of early Cretaceous Giumal shale and late Cretaceous Chikkim shale of Lagudarsi Group) from the Spiti region of the Indian Tethys Himalaya to assess paleo-weathering, redox ...

Therian Femora from the Late Cretaceous of Uzbekistan [PDF]

Acta Palaeontologica Polonica, 2012
Femora referable to metatherians and eutherians recovered from the Bissekty Formation, Dzharakuduk, Kyzylkum Desert, Uzbekistan (90 Mya), are described. Fourteen isolated specimens were sorted based on size and morphology into groups that likely correspond to the species level or higher.

Tidal-influenced transgression processes in late cretaceous Termit Basin, Niger

Frontiers in Earth Science
Tidal characteristics observed in sediment cores serve as significant indicators of marine paleo-environments. In order to comprehend the sedimentary processes taking place in the Termit Basin and its connections with the New Tethys and the southern ...
