Why is Mesosaurus fossil A good evidence that the continents of South America and Africa were once together?

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 fossils of the Mesosaurus can be found in South America and Africa?

The fossils of this prehistoric reptile have been discovered in eastern South America and southern Africa, and since Mesosaurus lived in freshwater lakes and rivers, it clearly couldn’t have swum across the expanse of the southern Atlantic Ocean.

Why was the Mesosaurus a significant piece of evidence to the continental drift?

Mesosaurus was significant in providing evidence for the theory of continental drift, because its remains were found in southern Africa, Whitehill Formation, and eastern South America (Melo Formation, Uruguay and Irati Formation, Brazil), two widely separated regions.

How does the occurrence of the same Mesosaurus fossils in South America and Africa support continental drift?

How does the occurrence of the same plant fossils in South America and Africa support continental drift? A land plant most likely could not travel across a large ocean such as the Atlantic. If the plant is found in both Africa and South America, those areas had to have been joined when the plant was growing.

What is the evidence that Africa and South America were joined?

To him, the presence of identical fossil species along the coastal parts of Africa and South America was the most compelling evidence that the two continents were once joined.

How does Mesosaurus fossil evidence support plate movement?

Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.

What does Mesosaurus fossil indicate?

They find these fossils embedded in hard, solid rock. Mesosaurus fossils have been found in South America and Africa. … The earliest fossil evidence for these animals indicates that they were alive about 300 million years ago, and their species went extinct about 260 million years ago.

What kind of creature was the Mesosaurus?

Mesosaurus was a lizard-like animal that lived in South America and Africa during the Permian Period. Mesosaurus is considered one of the earliest aquatic relatives of reptiles and mammals [1].

What kind of environment did the Mesosaurus live in?

Mesosaurus lived in freshwater lakes and ponds. Elongated and slim, it measured about 1 metre (3.3 feet) long. The skull and tail were both long and narrow, and the animal probably undulated through the water as it fed on small crustaceans and other prey with its jaws, which were full of long, thin, pointed teeth.

How did Mesosaurus fossils end up on two different continents?

Students figure out: The Mesosaurus fossils are found in hard, solid rock on two different plates of Earth’s surface: the South American and African plates. … 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.

What does the presence of Mesosaurus fossils tell about the initial location and positioning?

What does the presence of Mesosaurus fossils tell about the initial location and positioning? The Mesosaurus fossils tell us that South America, Africa and Antarctica were once connected because it is impossible for these reptiles to swim over the vast oceans and move from one continent to another.

Is there a possibility that Mesosaurus from South America could have swum the Atlantic Ocean to reach Africa?

For example, fossils of the ancient reptile mesosaurus are only found in southern Africa and South America. Mesosaurus, a freshwater reptile only one meter (3.3 feet) long, could not have swum the Atlantic Ocean. … South America and Africa were not the only continents with similar geology.

Which two continents contain fossils of Mesosaurus?

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. It would have been physiologically impossible for Mesosaurus to swim between the continents.

What evidence supports the idea that all continents were once joined together?

The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.

How the fossil evidence helped you to put the landmasses together?

Alfred Wegener collected diverse pieces of evidence to support his theory, including geological “fit” and fossil evidence. … This indicates that these continents had to be once joined together because the extensive oceans between these land masses act as a type of barrier for fossil transfer.

What evidence proves that South America Africa India and Australia were once covered by glaciers?
