Talk of PD Dr. Kenneth de Baets (GZN): „Gasping fish and panting belemnites: Warming, growth and migration of water-breathing animals “ in Hörsaal Geologie
On October 21, 5pm, PD Dr. Kenneth de Baets (GZN) will give a talk „Gasping fish and panting belemnites: Warming, growth and migration of water-breathing animals “ in Hörsaal Geologie, GeoZentrums Nordbayern, Schlossgarten 5.
The Pliensbachian-Toarcian transition has been considered a major bottleneck in the early evolution of belemnites probably related to major paleoenvironmental and paleogeographic changes during the Early Toarcian. Most of the previous research has been based on the study of belemnites from higher, temperate latitudes, while high resolution studies on diversity and size of subtropical belemnite as¬semblages in the NW Tethys are comparatively rare. The lack of high-resolution (ammonoid subzone) data on diversity and size distributions of belemnite assemblages does not allow separating changes during the Pliensbachian-Toarcian boundary event (Pli-Toa) from those during the Toarcian anoxic event (TOAE).
