Which two continents contain fossils of Mesosaurus, an extinct reptile, in similar regions of Pangaea?

Answer
A
Africa and South America
B
Eurasia and Africa
C
Australia and Eurasia
D
North America and Australia

Explanation

Mesosaurus fossils have been found in matching regions of eastern South America and western Africa. Because Mesosaurus lived in freshwater and could not have crossed a wide ocean, these fossil locations support the idea that the continents were once joined as part of Pangaea. The correct choice is Africa and South America.
