Paleontology: Ancient Marine Reptiles

  • In other words, what happens when a terrestrial animal returns to the water permanently?
  • Water is much denser than air, which affects all aspects of an animal's life including movement, sight, and hearing.
  • In addition, animals that return to the water cannot breathe water, and so must return to the surface for air.
  • Despite all these obstacles, many land animals have returned to the water throughout the course of evolutionary history.
  • This lesson will explore many different types of adaptations that modern and extinct animals have evolved to meet these challenges.
