The Mesozoic is characterized by a dramatic diversification of marine invertebrates and vertebrates. This affected both the existing marine ecosystems and the modern ecosystems that subsequently developed. Causes of the diversification include the end-Permian and Early Triassic mass extinctions, continental break-up, oceanic partitioning and sea-level fluctuations.
