How were fossils used as evidence for continental drift?
Fossil Evidence One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. 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.
What were the two major fossils that Dr Alfred Wegener used as evidence that the continents were once joined together?
Cynognathus and Lystrosaurus were land reptiles and were unable to swim. Figure 3. Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart.
What did Wegener use to support his theory of continental drift?
Wegener supported his theory by demonstrating the biological and geological similarities between continents. South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges.
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 are 3 pieces of evidence for Pangea?
They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
What was Wegener’s theory called?
continental drift
In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift.
What are 3 supporting factors of Wegener’s theory?
In proposing the theory of continental drift, Alfred Wegener relied on evidence from the shape of the continents, the distribution of plants and animals, similarities between landscapes, contiguous veins of ore that ran between continents, and the distribution of glacial deposits.
What are the 4 pieces of evidence supporting continental drift?
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 are 5 pieces of evidence of continental drift?
What was Alfred Wegener’s theory of continental drift?
Alfred Wegener proposed the theory of continental drift – the idea that the Earth’s continents move over hundreds of millions of years of geologic time – long before the idea was commonly accepted.
What kind of fossils did Alfred Wegener find?
Wegener believed this fact was one of the strongest pieces of evidence for his theory. In the above map, orange indicates the fossil remains of Cynognathus, a Triassic land reptile. Dark blue indicates fossil remains of the freshwater reptile Mesosaurus. Green indicates fossils of the fern Glossopteris, found in all of the southern continents.

What did Alfred Wegener believe to be Mesosaurus?
Wegener believed this fact was one of the strongest pieces of evidence for his theory. In the above map, orange indicates the fossil remains of Cynognathus, a Triassic land reptile. Dark blue indicates fossil remains of the freshwater reptile Mesosaurus.
How did Alfred Wegener explain the Continental shapes?
1. The idea proposed by Alfred Wegener to explain the continental shapes and positions is known as _____. A) Pangaea B) plate tectonics C) continental drift
Is there any fossil evidence to support Wegener’s theory?
It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory. Wegener himself did not collect the fossils but he called attention to the idea of using these scientific doc uments stating there were fossils of species present in separate continents in order to support his claim.
What is the evidence for the continental drift theory?
Another important piece of evidence in the Continental Drift theory is the fossil relevance. There are various examples of fossils found on separate continents and in no other regions.
What did Alfred Wegener find in Africa, India, and South America?
What did Alfred Wegener find in Africa, India, South America, Australia, that showed him that they were all covered by ice at one time? glacial striations Originally, scientists of Alfred Wegener laughed at him because there was no way the continents could crash through the surface of the Earth to move.
