we've learned about the asteroid impact that occurred at the end of the Cretaceous period of Earth history, which led to the extinction of the dinosaurs. It created a crater called the Chicxulub crater, and temporarily altered the Earth's atmosphere, climate, and oceans so much that it caused a mass extinction. (You might also find it helpful to look at this geologic time scale because it shows when the Cretaceous, Tertiary, Permian, and Triassic portions of the geologic time scale...

10. The age of the reptiles, the Mesozoic era, is marked by the rise of the phytoplankton (including diatoms & dinoflagellates), the great radiation of reptiles, and the dominance of the seed plants. The first mammals appear in the Triassic, but they are not a dominant species. Note the “small” mass extinction at the end of the Triassic. Flowering plants also appear and diversify in the Jurassic, but like the mammals, the do not dominate the biosphere. It isn’t until...
