Fossils Reveal Ancient Environments

Science · Dinosaurs & Paleontology · conceptual

Understand that fossils tell us not only about ancient animals but also about ancient environments — for example, marine fossils found on a mountaintop show that area was once underwater

What mastery looks like

  • Give an example of a fossil that reveals a past environment different from today's
  • Explain that finding marine fossils inland means that area was once covered by sea
  • State that plant fossils can show whether an area was once a forest, desert, or swamp

Check your understanding

If Fossils Reveal Ancient Environments heard that seashell fossils were found on a mountain, could they explain what that tells us about what the area used to be like?
