Which came first Cenozoic or Mesozoic?
The Phanerozoic Eon is divided into three eras, the Paleozoic, Mesozoic and Cenozoic eras. These were named for the kinds of fossils that were present. The Cenozoic is the youngest era and the name means “new life”. This is because the fossils are similar to animals and plants that are common today.
When did the Cenozoic Era start and end?

Mesozoic (252-66 million years ago) means ‘middle life’ and this is the time of the dinosaurs. This era includes the Triassic, Jurassic, and Cretaceous Periods, names that may be familiar to you.

What are 5 major events that happened in the Cenozoic Era?
What major events happened in the Cenozoic Era? Cenozoic Era major events including mass extinctions, the rise of mammals, changes in the climate, and the movement of continents into their present positions.
What is the youngest era?
We live during the Phanerozoic, which means “visible life.” This is the interval of geological time characterized by abundant, complex fossilized remains. Being the youngest eon of time, it is also very well represented by rock at Earth’s surface (because of the Principle of Superposition; see Section 1).
