Natura Nascosta Numero 35 Anno 2007 pp. 24-35 Figure 4 THE SOUTHWESTERN MARGIN OF BALTICA IN THE PALEOZOIC- EARLY MESOZOIC: ITS GLOBAL CONTEXT AND NORTH AMERICAN ANALOGUE Dmitry A. Ruban Abstract - Recent studies have provided evidence for long-termed activity of the shear zones at the southwestern margin of Baltica during the Paleozoic-early Mesozoic. In the late Paleozoic, the Northern Palaeotethyan Shear Zone formed the margin of Baltica and was one of the elements of the global system of megashears. The palaeotectonic analogue of the Paleozoic-early Mesozoic southwestern margin of Baltica may be found in North America, where long-distance displacements occurred at the western and southwestern margin during the Mesozoic-Cenozoic. Key words: shear zone, palaeotectonic analogue, Baltica, North America, Paleozoic, Mesozoic. Introduction The tectonic history of Baltica was reviewed by BOGDANOVA (1993), BOGDANOVA et al. (1996), NIKISHIN et al. (1996), TORSVIK et al. (1996), ARTEMIEVA (2003), and COCKS & TORSVIK (2005). A geologic abruptness of the western Baltica boundary was suggested much earlier (TORNQUIST, 1908). However, many relevant questions remain. The recent studies of the southwestern margin of Baltica (e.g., SAINTOT et al., 2003; DADLEZ et al., 2005; RUBAN & YOSHIOKA, 2005) suggest that the traditional concepts of the geodynamic evolution of this region need to be re-evaluated. Geodynamic outline In the Paleozoic, Baltica, now a part of Eurasia, was a medium-sized continent, which included the present-day territory of European Russia, Ukraine, Belorussia, the Baltic countries, the northeastern part of Poland, and the Scandinavian Peninsula. COCKS & TORSVIK (2005) have described Baltica as a terrane. -
The Fossil Record of Biodiversity in Angola Through Time: a Paleontological Perspective
Chapter 4 The Fossil Record of Biodiversity in Angola Through Time: A Paleontological Perspective Octávio Mateus, Pedro M. Callapez, Michael J. Polcyn, Anne S. Schulp, António Olímpio Gonçalves, and Louis L. Jacobs Abstract This chapter provides an overview of the alpha paleobiodiversity of Angola based on the available fossil record that is limited to the sedimentary rocks, ranging in age from Precambrian to the present. The geological period with the highest paleobiodiversity in the Angolan fossil record is the Cretaceous, with more than 80% of the total known fossil taxa, especially marine molluscs, including ammonites as a majority among them. The vertebrates represent about 15% of the known fauna and about one tenth of them are species firstly described based on specimens from Angola. O.
