Earlier studies of extinct taxa have shown that the scale features change among different specimens, across body areas, and during the growth of individuals, but there are always distinct species-specific characteristics of the scales, which can be used for the taxonomic identification of fishes and also for phylogenetic, palaeogeographical
, and other reconstructions (e.
The Alborz Region is usually shown as situated within the Gondwana domain in the palaeogeographical
reconstructions for the Ordovician (e.
2) The fine palaeogeographical
and past climatic knowledge of the study area will allow defining the effects of environmental changes on genomic variation in the course of time.
and P Chevremont (1994): Palaeogeographical
reconstructions of the Pan-African/ Brasiliano orogen; closure of an oceanic domain or intracontinental convergence between major blocks?
Chapter 1, 'The deep past', describes the geological and palaeogeographical
evolution of the coast of England from the late Quaternary and its settlement by people from c.
It will answer many questions about the age, environment and palaeogeographical
context of the Oligocene Shumaysi Formation in western Saudi Arabia.
Other topics include an overview of the tectonic and palaeogeographical
evolution of the area; silhouette and palaeoecology of Mesozoic trees; the Later Permian dicynodont fauna from Laos; the Mesozoic red bed sequences; and the palynology and stratigraphy of the Mesozoi Khorat Group red bed sequences from Thailand.
evidence suggests that the drying trend was established at 350ka and peaked at 17ka across the Australian continent (Kershaw and Nanson 1993; Kershaw et al.
The geological, geomorphological, stratigraphical, and palaeogeographical
aspects of the North Estonian Klint have been discussed in many works (see references in Suuroja 2005).
Part I Tectonic processes as driving mechanisms for palaeogeographical
and palaeoenvironmental evolution in Amazonia
reconstructions place all these localities at high southern latitudes during the Early Ordovician (Servais et al.
This edition has been revised and updated to incorporate the past ten years of research, presents chapters in terms of palaeogeographical
evolution, and includes color illustrations.
