Wegener had found the following evidence:

• Fossils of tropical species are often found in cold climates
• Similar rocks are found in southern Africa and Argentina
• Certain fossils are found in South America, Africa, India, Australia, and Antarctica—but not in North America, Europe, or northern Asia

Wegener described an ancient supercontinent called Pangea, consisting of all seven continents and many islands. Can you reconstruct Pangea using Wegener's evidence? Drag the continents around and see!
