Answer to Question 1

Answer: First, Mesosaurus is a freshwater reptile. It would not have been able to survive the trip across the southern Atlantic Ocean. Second, if it were able to swim such great distances as to be able to cross an ocean, it would be reasonable to assume Mesosaurus remains would be more widespread.

Answer to Question 2

Answer: The shorelines are continuously eroded by waves or are being built out by longshore currents, fluvial deposition, and so on. These processes change the shapes of the continents over time. The continental shelves are currently several hundred feet below the erosive power of the waves, so they are left relatively untouched.
