Maastrichtian to Ypresian-dated sediments from the 12 Frères borehole. (Fresco, southwestern Côte d'Ivoire), are here investigated for paleoenvironmental and paleogeographic significance. For this study, preparation of palynological slides in laboratory is done three steps.: (1) sampling physical treatment, (2) chemical attacks (HCl 10%, HF 40%) dissolve mineral matter preserve organic containe...
The ratite moa (Aves: Dinornithiformes) were a speciose group of massive graviportal avian herbivores that dominated the New Zealand (NZ) ecosystem until their extinction approximately 600 years ago. The phylogeny and evolutionary history of this morphologically diverse order has remained controversial since their initial description in 1839. We synthesize mitochondrial phylogenetic information...
Paleogeographical considerations on the development of the Paratethys and the Mediterranean during Oligocene and Miocene are presented in twelve time-slices. Plate tectonic activities and the collision of India with Asia caused the destruction of the Western Tethys Ocean in the Late Eocene. The Mediterranean and the intracontinental Paratethys basins came into existence as new marine realms. In...
