Paleogene floral assemblages around epicontinental seas and straits in Northern Central Eurasia: proxies for climatic and paleogeographic evolution
Paleogene connection of Tethyan and Paleoarctic water masses and biotas was largely enhanced by a N-S trending epicontinental seaway in northern Central Eurasia, which extended from the Aral Sea to the Amerasian deep basin of the Paleoarctic. This seaway enabled warm waters to impinge into polar lat...
