Global map showing the location of extant continents of the Middle Ordovician. Labeled landmasses include Laurentia, Siberia, Baltica, and Gondwana; labeled oceans include Panthalassa, Paleo-Tethys, and Iapetus.

Map showing the paleogeography of the Middle Ordovician (approximately 458 million years ago). Most researchers place western Arctic Alaska next to Siberia, next to Baltica, or in some intermediate position during the early Paleozoic Era (Blodgett et al. 2002; Dumoulin et al. 2002; Amato et al. 2009; Colpron and Nelson 2009; Strauss et al. 2017).
