Abstract
The distribution patterns of some 209 genera of Middle-Upper Ordovician corals and stromatoporoids are assessed using similarity indexes, levels of endemism, and relative proportions of major groups. The data is plotted on Scotese's Ordovician global map reconstructions, with the addition of inferred ocean currents. The patterns of distribution show that the American-Siberian assemblages occupied a broad, band-like spread across the equator influenced by warm, westward-driven currents. Euroasiatic associations were more restricted, controlled by the cooler, eastward-driven currents of south temperate latitudes. -Author
