all I need is sequence of events of Earth's history for the Mesozoic and Cenozoic eras.
just facts that I could put up. I believe the Mesozoic era was the fist one with humans in it?
(IN ORDER PLEAEE)
Deez -- I already posted a time line of events in those two eras for you.
The Mesozoic and Cenozoic eras are two major divisions of Earth's geological time scale. Let's go through the sequence of events for each era:
Mesozoic Era (252-66 million years ago):
1. Triassic Period (252-201 million years ago):
- Pangea begins to break apart, forming Laurasia and Gondwana.
- First dinosaurs appear.
- First mammals and turtles evolve.
2. Jurassic Period (201-145 million years ago):
- Dinosaurs experience a period of great diversification.
- First birds evolve.
- Coniferous forests dominate the landscape.
- Supercontinent Pangaea continues to break apart.
3. Cretaceous Period (145-66 million years ago):
- Dinosaurs continue to dominate, including large herbivores like Triceratops and long-necked Sauropods.
- Flowering plants (angiosperms) evolve and spread.
- Marine reptiles like ichthyosaurs and plesiosaurs thrive.
- Mass extinction event at the end of the Cretaceous wipes out non-avian dinosaurs.
Cenozoic Era (66 million years ago to present):
1. Paleogene Period (66-23 million years ago):
- Mammals undergo rapid diversification and adapt to various ecological niches.
- Primates, including early human ancestors, appear in the fossil record.
- Earth's climate cools and grasslands begin to emerge.
2. Neogene Period (23-2.6 million years ago):
- Grazing mammals, like horses and elephants, evolve and spread.
- First hominins (early human-like beings) appear.
- Ice Ages occur, leading to the formation of glaciers and dramatic changes in the environment.
3. Quaternary Period (2.6 million years ago to present):
- Modern humans (Homo sapiens) evolve.
- Extinction of many large mammal species, including mammoths and saber-toothed cats.
- Human civilization and technological advancements shape the environment.
It's important to note that humans did not exist during the Mesozoic Era. Homo sapiens appeared relatively recently in the Quaternary Period of Earth's history, which is part of the Cenozoic Era.
