How Did Wegener Explain The Fact That Ancient Horse Fossils?

Explanation: The Theory that Wagner came up with was called Continental Drift. The theory said that all of the continents had been connected at some time in the past. The fact that fossil evidence of horses were found on all the continents was one piece of evidence that supported the theory.

How fossil evidence helped support Wegener’s theory of continental drift?

One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined.

How did Wegener explain why fossils of land animals were found on continents that are across oceans from one another animals evolved separately on EA?

How did Wegener explain similar fossils on different continents? Since neither reptile could have swum great distances across salt water he inferred that they once lived on a single landmass that has since split apart.

Which animal fossil helped support the theory of continental drift?

Lystrosaurus fossils
Lystrosaurus fossils may serve as indicators of the boundary between the Permian and Triassic periods and also are part of the body of evidence supporting the theory of continental drift .

What evidence have you discovered to explain how similar fossils could be found on continents that are now separated by vast oceans?

The only way these fossils can be found on continents that are separated by oceans is if the continents were once together (connected). These ancient animals and plants could not have swam across oceans!

How do fossil records show evidence of evolution?

Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.

Which fossil gives the best evidence that the continents were once all together?

Evidence. Two fossils in particular served as good evidence for the idea that the continents were once joined but have since separated: Glossopteris and Mesosaurus.

Why was Wegener interested in finding fossils of the same plants and animals on two different continents?

Why was Wegener interested in finding fossils of the same plants and animals on two different continents? He reasoned that if the connivers had once been joined, fossils of the same plants and animals should be found in areas that had once been connected.

What kind of fossil plant evidence proved that the continents are drifting?

Cycads date back in the fossil record to a time when dinosaurs roamed the land and when the earth’s continents were united. It is believed that continental drift has resulted in the present worldwide distribution of this ancient group of seed plants.

What interesting thing did Wegener discover about fossils of tropical organisms?

Wegener also found that the fossils found in a certain place often indicated a climate utterly different from the climate of today: for example, fossils of tropical plants, such as ferns and cycads, are found today on the Arctic island of Spitsbergen.

What were 3 pieces of Wegener evidence to support continental drift theory?

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.

How the fossils evidence were used to prove or support the theory of plate tectonics?

Finding identical or similar fossils in areas separated by vast distances were some of the first clues that scientists used to reconstruct past plate movement. This distribution of fossils led to theories that the southern continents were once joined in a supercontinent called Gondwana.

Why were Cynognathus fossils were important to Wegener’s theory ?( 1 point?

Why were Cynognathus fossils were important to Wegener’s theory? They were found on lands now separated by a wide ocean.

How do scientists explain the existence of fossils of the same plants?

Fossils from many millions of years ago also show that one big continent had once existed and then broken apart. The fossils of the same ancient plants and small dinosaurs are found on different continents.

Why did most scientist reject Wegener’s theory?

The main reason that Wegener’s hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth’s spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.

What was the main idea of Wegener’s continental drift theory?

Wegener’s continental drift theory introduced the idea of moving continents to geoscience. He proposed that Earth (opens in new tab) must have once been a single supercontinent before breaking up to form several different continents.

How would Wegener have interpreted the fossil evidence?

How would Wegener have interpreted the fossil evidence, if it showed the plants at Svalbard in Norway lived long ago in a tropical climate? He would have concluded that they support his theory of continental drift.

What did Alfred Wegener notice about fossils?

Wegener found fossil evidence that the continents were once joined (Figure below). The same type of plant and animal fossils are found on continents that are now widely separated. These organisms would not have been able to travel across the oceans.

How did Wegener explain why fossils of land animals were found on continents that are across oceans from one another quizlet?

How did Wegener explain why fossils of land animals were found on continents that are across oceans from one another? Continents were once one landmass and have drifted apart.

What did Wegener discover about plants and animals on different continents?

In 1915 the German geologist Alfred Wegener (left) was struck by the fact that identical fossil plants and animals had been discovered on opposite sides of the Atlantic. Since the ocean was too far for them to have traversed on their own, Wegener proposed that the continents had once been connected.

How did Alfred Wegener’s theory explain the movement of the continents?

He hypothesized that all of the modern-day continents had previously been clumped together in a supercontinent he called Pangaea (from ancient Greek, meaning “all lands” or “all the Earth”). Over millions of years, Wegener suggested, the continents had drifted apart.
