The Mesozoic Era [3] is the second-to-last era of Earth's geological history, lasting from about 252 to 66 million years ago, comprising the Triassic, Jurassic and Cretaceous Periods. It is characterized by the dominance of archosaurian reptiles, such as the dinosaurs; an abundance of gymnosperms, (such as ginkgoales, bennettitales) and ...As the Mesozoic was the age of reptiles, so was the Cenozoic the age of mammals. During the Tertiary, mammals took over the econiches left empty by the then-extinct dinosaurs, just as these had occupied econiches left vacant after the end-Permian extinction. Like the dinosaurs, mammals rapidly grew in numbers and varieties.

Over the Late Cenozoic (from 30 Ma), we predict a long-term decrease in preserved continental sediment volume.

Mesozoic Era, Second of the Earth’s three major geologic eras and the interval during which the continental landmasses as known today were separated from the supercontinents Laurasia and Gondwana by continental drift. Take the two most recent geological eras: the Mesozoic, which means “middle life,” and the Cenozoic, which means “recent life.”. These eras are distinguished by fossil records, which include animals, plants, and other life forms of all shapes and sizes.
