How did Wegener explain the fact that ancient mesosaurus fossils showed up on different continents?
A) The continents were connected by land bridges.
B) The mesosauruses swam between the two continents.
C) The continents were at one time joined together.
The correct option is C. Wegener proposed the continental drift hypothesis, which says that all the continents were once connected as one land mass which broke apart about 250 millions years ago and move apart slowly to their current locations.
C. Pangia was an unpoular idea, but once Wegener proposed the idea that we live post-breakage of the joined continents, things started to make more sense.
