part a: which statement best explains the presence of mesosaur fossils in these locations? a. south america and africa were joined together when mesosaurs were alive. b. south america and africa became separated by an ocean before mesosaurs lived. c. south america and africa once had a land - bridge, which allowed mesosaurs to travel between the continents. d. south america and africa had very different climates, which allowed mesosaurs to migrate through the ocean. part b: circle one phrase in each set of options to make a conclusion about the types of rock in the locations where mesosaur fossils are found. the rock containing mesosaur fossils is most likely (the same / a different) age and (the same / a different) type on both continents.

Answer

Brief Explanations:

For Part A, the presence of mesosaurus fossils on both South America and Africa is best explained by the fact that these continents were joined together during the time mesosaurs existed, supporting the theory of continental drift. For Part B, since the fossils are of the same species found across what are now separate continents that were once connected, the rock containing the fossils is most likely the same age and the same type on both continents.

Answer:

Part A: A. South America and Africa were joined together when mesosaurs were alive. Part B: The rock containing mesosaur fossils is most likely the same age and the same type on both continents.
