We live in the Cenozoic era, and scientists know more about this era and the epochs it’s divided into than any other time period. Why is this? A. We know more about the Cenozoic era because this is the only era that has had a wide diversity of species living on Earth. B. We know more about the Cenozoic era because this is the most recent time period in the history of the Earth, and we have more information available to study. C. We know more about the Cenozoic era because the planet’s poles reversed magnetic fields at the beginning of this era. D. We know more about the Cenozoic era because fossils don’t exist to document previous eras.

For this activity, you will be reviewing the geological time scale in the module readingassignment from the Geological Time chapter in the PRI Digital Atlas of Ancient Life –online textbook and the Earth History chapter from the OER Commons Earth ScienceTextbook. Use the images of the geologic time scales in your readings to help you makeyour Geologic Time Scale concept sketch nstructions:Sketch and label a geologic time scale. Include dates of the following events in EarthHistory on your time scale in the appropriate time period (you may have to look these up onthe internet but most are listed in your readings). First appearance of free oxygen in the atmosphere Earliest fossils Oldest animal fossils Great Dying Extinction (worst mass extinction at end of the Permian Period) – alsoexplain possible causes of this extinctionArchaeopteryx sp. appeared First Flowering PlantsTyrannosaurus rex appeared K-T Extinction event (Dinosaurs died out) – also explain possible causes of…
Let’s see what you already know! For this activity, you are a palaeobiologist interested in reconstructing ancient ecosystems. You have searched the scientific literature and found 5 clues:1. The majority of the field site (~100 km2) is mostly covered with limestone. However, in one area younger mudstone rocks are preserved above the limestone.2. The limestone has many invertebrate fossils including starfish, sea urchins, and coral, but mostly has bivalve shells. 3. The limestone also has vertebrate fossils. Small shark teeth are sometimes found. A single elasmosaurid plesiosaur tooth was discovered. Amazingly, several coprolites (fossilised dung) have fish vertebrae found in them; one coprolite even has a feather inside!4. The mudstone is rich in tiny ‘microfossils’ that include:• Small mammalian teeth • Pollen from 29 different families of flowering plants: the most common families are Caesalpiniaceae (peacock flowers)5. The mudstone also has larger fossils, including:• Pelvic and…
