The Mesozoic era was tropical and the Paleozoic was dry.
The climate of the Cretaceous was apparently fairly mild and uniform, but it is possible that toward the end of the period some variant zones of climate had appeared, making the overall climate cooler. Such changes, along with changes in both the earth's surface and its flora and fauna, brought the Mesozoic to a close.
End of the Mesozoic era
Mass extinction
