The Mesosaurus could not swim between the continents in the open ocean, so the fossils show that the continents must have been together in the past.
Explanation:
One critical point in the use of Mesosaurus to explain continental drift is that they could not swim between the continents in open ocean.
Mesosaurus is known as middle lizard and its fossils have been used to proof that continental drifts truly result. Alfred Wegener is credited with the hypothesis of continental drift in which the land masses where once joined together.
- The fossils of this ancient organism have been discovered in the Southern part of Africa and Eastern part of South America.
- Both continents were once believed to be joined together in geologic time past.
- Mesosaurus was a swamp dwelling animal that could not have swim between the two continents. The ocean will pose a barrier. For its fossils to be found on the two continents, the land masses must have been joined together.
