This statement is true since the formation of this ocean arose 200 million years ago, making it the last in shape during the division of the Pangea supercontinent.
Pangea began to fragment due to the force of Earth's tectonic plates, separating the ancient continent of America and leaving a large body of water in between.
Explanation:
The second major phase of Pangea's disintegration began at the beginning of the Cretaceous (150-140 million years ago), when the supercontinent Gondwana divided into four smaller continents (Africa, South America, India, and Antarctica / Australia).
