TL;DR: In this paper, the authors investigated the early Cambrian shallow-to-deep-water sequences of the Yangtze Platform and proposed a high-resolution stratigraphic framework for multidisciplinary analyses of the Cambrian explosion.

TL;DR: The observed regional biodiversity through this interval has both evolutionary and taphonomic influences: the decline in SSF diversity beginning in the upper Meishucunian was not only related to the decimation of SSFs, but also to a reduction in phosphogenesis.

TL;DR: In this article, organic matter reflectance, illite crystallinity, and fluid-inclusion techniques have been used to evaluate burial metamorphic conditions for the lithostratigraphic successions that accumulated during the Cretaceous in the southern Benue trough and Anambra basin of southern Nigeria.

TL;DR: The Huanghuachang section near Yichang, southern China was successively approved by ISOS, recognized by ICS and then officially ratified as being the Global Stratotype Section and point (GSSP) for the base of the Middle Ordovician Series and the Third Stage, named as Dapingian, of the Ordovicians as mentioned in this paper.

TL;DR: In this article, the rank and composition of Upper Cretaceous-Tertiary coals from five localities (Enugu, Orukpa, Okaba, Ihioma and Azagba-Ogwashi) in Southern Nigeria are described.
