Questions and Answers

What does the presence of fossils of the same age and species on different continents suggest?

  • That these continents were once connected (correct)
  • That these fossils were carried by ocean currents
  • That these species migrated from one continent to another
  • That these species evolved independently on each continent

    • What is the significance of fossils of tropical plants found in Arctic regions and fossils of marine animals found in mountain ranges?

  • These fossils are evidence of species migration
  • These fossils are evidence of sudden changes in sea levels
  • These fossils indicate that these areas were once connected (correct)
  • These fossils are evidence of sudden changes in climate

    • What can be inferred from fossilized tracks and burrows found on different continents?

  • That these tracks and burrows were created by the same species
  • That these tracks and burrows show similar patterns and characteristics (correct)
  • That these tracks and burrows were created at the same time
  • That these tracks and burrows were created by different species

    Study Notes

    Fossil Evidence

    Similarity of Fossil Species

    • Fossils of the same age and species found on different continents, suggesting a common origin
    • Examples: Mesosaurus (a freshwater reptile), Glossopteris (a fern), and Cynognathus (a mammal-like reptile)

    Distribution of Fossil Species

    • Fossils found in areas that are now separated by oceans, indicating that these areas were once connected
    • Examples: Fossils of tropical plants found in Arctic regions, and fossils of marine animals found in mountain ranges

    Fossilized Tracks and Burrows

    • Fossilized tracks and burrows found on different continents, showing similar patterns and characteristics
    • Examples: Fossilized dinosaur tracks found in Africa, North America, and Europe, and fossilized worm burrows found in Africa and South America

    Climate Indicators

    • Fossils of plants and animals that are adapted to specific climates, found in areas that are now different from their original climate
    • Examples: Fossils of tropical plants found in Antarctica, and fossils of cold-adapted plants found in the Sahara Desert

    Age of Fossils

    • Fossils of the same age found on different continents, indicating a common geological history
    • Examples: Fossils of the same age found in the Appalachian Mountains and the Atlas Mountains, and fossils of the same age found in the Andes and the Himalayas

    Fossil Evidence for Common Origin

    • Fossils of the same age and species found on different continents suggest a common origin, such as Mesosaurus, Glossopteris, and Cynognathus.
    • These fossils were found in different parts of the world, implying that the continents were once connected.

    Distribution of Fossil Species Across Continents

    • Fossils found in areas that are now separated by oceans indicate that these areas were once connected, such as tropical plants in Arctic regions and marine animals in mountain ranges.
    • This distribution suggests that continents have moved over time.

    Fossilized Tracks and Burrows

    • Fossilized tracks and burrows found on different continents show similar patterns and characteristics, such as dinosaur tracks in Africa, North America, and Europe, and worm burrows in Africa and South America.
    • These similarities suggest that the same species were present on different continents.

    Climate Indicators in Fossils

    • Fossils of plants and animals adapted to specific climates are found in areas that are now different from their original climate, such as tropical plants in Antarctica and cold-adapted plants in the Sahara Desert.
    • These fossils indicate that the climate has changed over time.

    Age of Fossils and Geological History

    • Fossils of the same age are found on different continents, indicating a common geological history, such as in the Appalachian Mountains and the Atlas Mountains, and in the Andes and the Himalayas.
    • This suggests that the continents have shared a common geological history.
