Outline of Final Research Achievements

Belemnites (Belemnitida), a very successful group of Mesozoic cephalopods, provide an important clue for understanding Mesozoic marine ecosystems. Following current hypotheses, belemnites originated in the earliest Jurassic (201 to 197 Ma) with very small forms without prominent groove. According to this view their paleobiogeographic distribution was restricted to northern Europe until the Toarcian (183 to176 Ma). The fossil record is, however, biased by the fact that all the previous studies on belemnites so far focused on Europe. This study on fossil records conclude that the late Triassic to earliest Jurassic Belemnitida had a much higher diversity, and wider distribution than previously thought. It is postulated here that the belemnites did not originate in the earliest Jurassic in northern Europe, but in the Late Triassic in eastern Tethys (S.China). The fossil record of the Order Belemnitida is therefore extended by ~33 m.y. before the Triassic-Jurassic extinction event.
