The present article is a review of a palaeobiogeographic analysis of Jurassic Ostracods from East Africa, India and Madagascar and includes also some general remarks on palaeobiogeography, biodiversity and Ostracod ecology.The palaeobiogeographic study shows the high significance of this microfossil group for the reconstruction of palaeogeographic processes, particularly plate tectonic developm...

to assess biogeographic affinity of the late cambrian (furongian) and the early ordovician (late tremadocian) faunas of eastern alborz, a multivariate cluster analysis using the pair-group raup-crick similarity index has been applied. the late cambrian fauna of alborz shows clear gondwanan signatures with the closest affinities to the contemporaneous faunas of temperate latitude peri-gondwana (...

The larger benthic foraminifera Gyroconulina columellifera Schroeder & Darmoian, 1977 (type-locality: Maastrichtian Aqra Formation of Iraq) is described for the first time from two sections of the Maastrichtian Tarbur Formation of the Zagros Fold-Thrust-Belt, SW Iran. New details on its wall microstructure are provided. The microfacies is represented by bioclastic wacke-/pack-/grainstones with ...
