Mesozoic Marine Revolution

Mesozoic Marine Revolution

The Mesozoic marine revolution (MMR) was a fundamental restructuring of marine ecosystems during the Mesozoic era, particularly in the Jurassic and Cretaceous,[1] caused by increased predation pressure.

The term was coined by Geerat J. Vermeij (1977) based on the earlier work of Steven M. Stanley (1974).[2][3]

The MMR was not the first bout of increased predation pressure; this also occurred around the end of the Ordovician.[4]

Some taxa began to diversify before the MMR, notably the crinoids, who were perhaps responding to increased benthic predation pressure.[1]

Casualties

Organisms which went into decline include stalked crinoids, articulate brachiopods, and endobyssate bivalves.[2] Weakly armoured gastropods also disappeared, while more heavily armoured taxa diversified.[5]
