End triassic: 200 million years ago, 80% of species lost, including all conodonts end cretaceous: 66 million years ago, 76% of species lost, including all ammonites, mosasaurs, plesiosaurs, pterosaurs, and nonavian dinosaurs smaller extinction events have occurred in the periods between, with some dividing geologic time periods and epochs. Witness the 1906 san francisco earthquake and the break up of pangaea 200 million years ago. data driven visualizations illustrate earth’s story, revealing how subtle motions and sudden ruptures have shaped our planet over eons—and how geological activity influences the course of human history. Today’s configuration of continents is dramatically different than it was in the past. see how plate tectonics built and fragmented supercontinents—land masses made of multiple continents merged together—over the past 200 million years. for more on earthquakes—why they happen, how they’ve shaped the bay area, and what you can do to prepare for future events—visit calacademy.org.

Explore the university of california museum of paleontology for insights into earth's history, fossils, and evolutionary biology. After this time period, oxygen levels gradually increased, which allowed for the species and organisms that we're familiar with to evolve and develop. it's believed that right after 200 million years ago, large groups of ocean dwelling creatures called diatoms drastically increased the oxygen levels in the atmosphere. This set of globes shows a three dimensional view of muller and colleagues’ geodynamic model results at 200 million years ago, 100 million years ago, and present day. these globes are centered. Life appeared on earth around 3.8 billion years ago. the first living organisms were simple bacteria, which developed in water. over the course of time, these organisms multiplied and diversified. some left the oceans for the terra firma. some even managed to become airborne. today, millions of species and billions of individuals populate our planet. these species have undergone numerous.
