Great Ordovician Biodiversification Event information
Evolutionary radiation of animal life throughout the Ordovician period
The Great Ordovician Biodiversification Event (GOBE), was an evolutionary radiation of animal life throughout[1] the Ordovician period, 40 million years after the Cambrian explosion,[2] whereby the distinctive Cambrian fauna fizzled out to be replaced with a Paleozoic fauna rich in suspension feeder and pelagic animals.[3]
It followed a series of Cambrian–Ordovician extinction events, and the resulting fauna went on to dominate the Palaeozoic relatively unchanged.[4]
Marine diversity increased to levels typical of the Palaeozoic,[5] and morphological disparity was similar to today's.[6]
The diversity increase was neither global nor instantaneous; it happened at different times in different places.[4] Consequently, there is unlikely to be a simple or straightforward explanation for the event; the interplay of many geological and ecological factors likely produced the diversification.[1]
