Stable platform and dynamic oceanic palaeogeography

Abstract

Tropical-subtropical fossils (certain fusuline foraminifera, certain radiolaria, certain bivalves, certain corals) of Permian and Jurassic age now occur in Northern Pacific Asian and North American marginal areas. Their presence indicates original locations in tropical-subtropical, warm water “central” Panthalassa from which they were transported and accreted to cooler water areas. This information, palaeontological and lithological is the basis for the conclusions made here.
