The eastern coast of South America and the western coast of Africa are separated by the Atlantic Ocean. If scientists find the s
ame types of plant fossils on the eastern coast of South America and the western coast of Africa, which of these would be the best conclusion? A.
The oceans were formed after dinosaurs went extinct.
B.
The climate in each continent has changed.
C.
Dinosaurs once lived in both of these regions.
D.
At one time, the two continents were one landmass.
If scientists find the same types of plant fossils on the eastern coast of South America and the western coast of Africa, this suggests that at one time, the two continents were one landmass. When the continents separated, the communities of plants were split, resulting in identical fossils on each coast millions of years later.
