Developments in Hydrobiology  
During the earliest Triassic, the neritic environments were completely devastated and the recolonization of biotopes was very slow. Besides some small foraminifera and bivalves, ostracods are among the few neritic organisms that were able to survive and/or to thrive in the inhospitable environments after the disaster events. But the Permian-Triassic boundary marks also a great change in the ostracod assemblages. The Palaeozoic ostracods left room for the "modern" fauna. New data on the Early

First "typically modern" forms appear already in the Late Permian. The Early Triassic (Griesbachian to Spathian) ostracod faunas display a mixture of Palaeozoic and Mesozoic taxa. Completion of the Palaeozoic-Mesozoic turnover could be located in the Middle Triassic (Anisian).
