    Study Notes

    Dinosaurs Alive!

    • This film is a global adventure of science and discovery
    • It follows paleontologists in locations like Mongolia's Gobi Desert and New Mexico
    • It uses computer-generated imagery (CGI) to showcase dinosaurs
    • It helps connect the film to science curriculum through key concepts

    Key Concepts

    • Science is an Ongoing Process: Scientific knowledge evolves with new evidence. Paleontologists constantly unearth new fossils, and discoveries can change our understanding of dinosaurs.
    • Tools and Technologies Enable Discovery: Shovels, brushes and compasses and cutting-edge technologies (GPS, satellites, digital x-rays, CAT scans) are crucial for paleontologists to find and analyze fossils. These tools reveal information like fossil location, dinosaur size, and diet.
    • Fossils Reveal Dinosaur Life: Fossils of bones, skin impressions, feathers, footprints, and coprolites reveal dinosaur behavior, diet, speed, and other aspects of their lives.
    • Earth Has a Vast History: Scientists divide Earth's history into eras, periods that demonstrate the evolution of dinosaurs and other organisms, and how organisms have changed over time.

    Dinosaurs Are Diverse

    • Dinosaurs are a highly successful group of animals with a wide array of features
    • They ranged from small carnivorous dinosaurs to massive herbivores
    • Their diverse body features (crests, horns, and others) were used for defense and display

    Birds Are Living Dinosaurs

    • Dinosaurs are not extinct
    • Birds are descendants of small carnivorous dinosaurs
    • They survived the catastrophic extinction event that wiped out many other dinosaurs
