Your question: Why fossils of the Mesosaurus can be found in South America and Africa?

It would have been physiologically impossible for Mesosaurus to swim between the continents. This suggests that South America and Africa were joined during the Early Permian. … It is found as fossils only in South Africa and South America.

Why are Mesosaurus fossils found in South America and Africa continents that are now thousands of kilometers and an ocean apart?

As you determined in the previous lesson, there is a divergent plate boundary between the South American Plate and African Plate. … This divergent plate motion explains why the fossil remains of Mesosaurus that were once together are now found on continents thousands of kilometers apart.

How did the Mesosaurus fossils on the South American plate and African plate get so far apart?

How did the Mesosaurus fossils on the South American Plate and African Plate get so far apart? Earth’s plates travel at a rate too slow to be experienced by humans. It takes a long time for Earth’s plates to travel great distances. The Mesosaurus fossils moved apart gradually over tens of millions of years.

What fossils were found in South America and Africa?

For example, fossils of ancient reptiles called Cynognathus and Mesosaurus have been found on South America and Africa. Also, fossils of the plant Glossopteris have been found on South America, Africa, India, Antarctica, and Australia.

Why were the fossil remains of Mesosaurus?

Why were the fossil remains of Mesosaurus important to Alfred Wegener? They proved that Earth is composed of several rocky tectonic plates. They proved that Mesosaurus is extinct. They were the first fossils discovered in Africa and South America.

Why is South America moving away from Africa?

According to the study, the tectonic plates attached to the Americas are moving apart from those attached to Europe and Africa by four centimetres each year. As the plates move, researchers say new plates form to replace them at the central point between the regions, known as the Mid-Atlantic Ridge.

Is the presence of animal fossils tells the South America Africa and Antarctica were once connected?

Many scientists thought that Africa, India, Australia, South America, and Antarctica had once been connected into a large ancient continent known as Gondwana. … Those fossils belonged to a species previously found in Africa, providing further evidence that the distant present-day continents were once connected.

What happened with the plates and mantle between South America and Africa?

Students figure out: The South American and African plates moved apart as a divergent boundary formed between them and an ocean basin formed and spread. … At divergent plate boundaries, rock rises from the mantle and hardens, adding new solid rock to the edges of both plates.

Can Mesosaurus swim long distance?

Mesosaurus were among the first reptiles to live in and around water, and they spent most of their lives in the water. However, their bodies weren’t built for swimming long distances, so they stayed close to land.

What age are the fossils of the reptile Mesosaurus found in Africa and South America?

Mesosaurus, (genus Mesosaurus), early aquatic relative of reptiles, found as fossils from the Early Permian Period (299 million to 271 million years ago) in South Africa and South America.

Is the presence of animal fossils tells that South America?

Answer. Answer: A German scientist named Alfred Wegener proposed that all of the continents once had been joined in a supercontinent that he called Pangaea. … Wegener found the same rock formations and fossils in Africa, South America, and Antarctica.

Were India and Africa connected?

India was still a part of the supercontinent called Gondwana some 140 million years ago. The Gondwana was composed of modern South America, Africa, Antarctica, and Australia. When this supercontinent split up, a tectonic plate composed of India and modern Madagascar started to drift away.

What are 3 pieces of evidence for Pangea?

Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

Where was the Mesosaurus fossil found?

Remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America.

When two plates move together lithosphere is quizlet?

Convergent Boundaries: occurs where two plates move together, oceanic lithosphere plunging beneath an overriding plate.

What was the first line of evidence that led early investigators?

Alfred Wegener is credited with developing the continental drift hypothesis. What was probably the first evidence that led some to suspect the continents were once connected? The puzzle-like fit of the continents, especially Africa and South America.
