Why the discovery of fossil remains in both South America and Africa?

Why are there fossils of the same species in South America and Africa?

They move at a very slow rate – usually measured in millions of years – and continents are either torn apart or collide together to form very large single continents. Fossils of the same genus/species suggest that contents that were once together, must have been together in the geological past.

Why the discovery of fossil remains in both South America and Africa but nowhere else supports the continental drift theory?

This formed one very large habitat for the mesosaurus, as the southern portions of South America and Africa had the same climate conditions. This resulted in the mesosaurus to be able to spread on both of these continents because at that time they were one, thus there wasn’t any barrier between them.

Why was the discovery of the same fossils on separate continents?

Fossil Evidence

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.

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

Answer: Yes, because these fossils indicated the former connections of the continents before which was called Gondwana in the Triassic Period, 200 million years ago.

Were Africa and South America connected?

According to plate tectonic evidence, Gondwana was assembled by continental collisions in the Late Precambrian (about 1 billion to 542 million years ago). … The South Atlantic Ocean opened about 140 million years ago as Africa separated from South America.

What are 5 pieces of evidence that support continental drift?

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.

What explains the existence of Mesosaurus fossils in both Africa and South America?

Wegener explained that Mesosaurus fossils were found on Africa and South America this way: Africa and South America were joined when Mesosaurus lived and then moved apart. Mesosaurus was a swimming reptile so it swam across the Atlantic Ocean. a land bridge across the Atlantic Ocean connected the two continents.

What does Pangaea mean in Greek?

Pangea was surrounded by a global ocean called Panthalassa, and it was fully assembled by the Early Permian Epoch (some 299 million to 273 million years ago). … Its name is derived from the Greek pangaia, meaning “all the Earth.”

What is evidence that Africa was once cold?

Proof that shows Africa was once cold includes evidence of glacier scars and deposits.

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.

Why are the fossils of Mesosaurus found today in some rock layers in both South America and Africa?

Which reason best explains why fossils of this animal are found on both continents today? The ocean between the two continents was once frozen, and the Mesosaurus traveled across the ice. The continents were once joined together as a single land mass. The Mesosaurus swam across the ocean due to its migration.
