The fossil symbols and mountain belts were helpful because it showed where the land and water dinosaurs were able to live, especially with the non-swimmers in Africa and South America. There is proof of some mountains matching in Western Europe and Greenland.
Answer:
a vestigial structure
Explanation:
Vestigial structures are a rudimentary (or even functionless) version of a body part, but they have important functions in a closely correlated or evolutionarily close species, an example of which is the presence of eyes in fish of the genus Astyanax. The existence of these vestigial structures is strong evidence that evolution occurs in organisms, since this structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.
