Research Abstract

Belemnites, an extinct group of cephalopods, flourished in Mesozoic oceans. The rich and continuous fossil record of belemnites offers the potential for understanding the evolutionary dynamics of nektonic biota and its environmental factors. This study reveals two major biogeographic changes in the Early Cretaceous belemnites in the Pacific; 1) Occurrence of pandemic distribution of Tethyan-type belemnites, which can be correlated with the beginning of the Mid-Cretaceous global warming, and 2) An enigmatic distribution pattern of the Barremian belemnite in the NW and NE Pacific,indicating an existence of the “Cretaceous North Pacific Gyre”.
