Mesosaurus was one of the first reptiles to return to the water in which its
amphibian ancestors originally lived. Its feet were webbed, body streamlined,
and its long tail supported a fin. Since the hind legs were much longer, they
are presumed to have been used to propel the creature through the water. Its
body was flexible and could easily move sideways, but it could not turn as a
result of highly thickened ribs (a feature also seen in modern sea cows).
