The purpose of this chapter is to define, characterize and illustrate the distinct domains that
composed the Iberian Penisula during the Lower Paleozoic (from Cambrian-Ordovician to …

This study presents a Cambrian–Ordovician (Cambrian,'Series 3'–Katian, Ka4) brachiopod α-

Different kinds of fossils have different patterns of palaeogeographical distribution. This has
led to differing palaeocontinental reconstructions in the early Palaeozoic. We take the early …

Las formaciones del Ordovícico Medio del Anti-Atlas (sur de Marruecos) han librado un
variado registro de trilobites, moluscos, equinodermos, braquiópodos, graptolitos …
