| Abstract | During the 5th International Meeting on Mesozoic Fishes held at Santillo, Mexico, we first presented the great novelty of the marine Triassic findings in southern China. The discovery and following first studies had already shown their important implications not only for paleontology but also for paleogeography. One advantage of fishes over marine reptiles is their size when we want to recognize an assemblage and compare it to others. Fishes indeed are far smaller and more numerous than reptiles, so that the chances to have a 'complete' fish assemblage are much higher. We believe that very fast migrations were possible, but not all the fishes were either interested or able to travel such a long distance. Oceanic currents in the Tethys had clockwise direction in the northern hemisphere, making westwards migration easier in the tropical region where our fishes lived. |
