There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. If Continental Drift had not occurred, the alternative explanations would be: The species evolved independently on separate continents – contradicting Darwin’s theory of evolution.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.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 . Lystrosaurus was roughly 1 metre (about 3 feet) long and was heavily built.

How did continental drift affect dinosaurs?
The resulting ecosystems produced less food than the environments in which dinosaurs evolved and were unable to sustain them. A gradual decline in the number of dinosaur species would likely mirror an equally gradual cause of their ultimate extinction.
How the fossil evidence helped you connect the continents together?
Plant and animal fossils also reveal evidence. There are various examples of fossils found on separate continents and in no other regions. This indicates that these continents were once joined together because the extensive oceans between these land masses act as a barrier for fossil transfer.
How did plant and animal fossils influence the theory of continental drift?
Fossils of similar organisms across widely disparate continents encouraged the revolutionary theory of continental drift. Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics.
How were fossils used as evidence in plate movement?
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.
How did Wegener explain why fossils of land animals were found on continents that are across oceans from one another?
How did Wegener explain why fossils of land animals were found on continents that are across oceans from one another? – Animals evolved separately on each continent.

What Do Fossils Have to Do with Wegener’s Theory? – Sciencing
In this, and several further papers and books, Wegener used evidence from the fossil record to support his theory of continental drift.
Why science took a slow dinosaur to Pangaea – Big Think
From the mid-19th century, fossils were used as evidence for continental drift – but mainstream scientists didn’t buy it until the 1950s.
How Fossils Confirmed the Dance of the Continents
Fossils found in Antarctica were crucial in recognizing continental drift.
Continental Drift – Extinction: What Killed the Dinosaurs? – PBS
Depending on location and interpretation, the fossil record seems to say different things. According to some scientists, fossil evidence clearly shows a decline …
Why is fossil evidence good?
Key Points. 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.
Did continental drift happen before or after the dinosaurs?
Continental Drift Leads to Speciation
When dinosaurs first came onto the world’s stage during the late Triassic period of the Mesozoic era—about 220 million years ago—the Earth’s land masses were still united in one comprehensive continent—Pangaea.
What did the continents look like when dinosaurs?
All continents during the Triassic Period were part of a single land mass called Pangaea. This meant that differences between animals or plants found in different areas were minor. The climate was relatively hot and dry, and much of the land was covered with large deserts. Unlike today, there were no polar ice caps.

What continents were dinosaurs on?
North and South America, Europe, Asia, Africa, Antarctica and Australia–or, rather, the landmasses that corresponded to these continents during the Mesozoic Era–were all home to an impressive assortment of dinosaurs between 230 and 65 million years ago.
How is fossil record evidence of evolution?
Fossils provide evidence for the evolutionary change through now extinct forms that led to modern species. For example, there is a rich fossil record that shows the evolutionary transitions from horse ancestors to modern horses that document intermediate forms and a gradual adaptation o changing ecosystems.
How were the fossil symbols and mountain belts helpful in deciding where to move the continents?
How were the fossil symbols and mountain belts helpful in deciding where to move the continents? They made it a lot easier to see where to put the pieces. Otherwise, it was really hard to fit them all together. Why don’t the present shapes of the continents fit perfectly into a supercontinent?
Why was the discovery of different fossils so significant?
Through the process of evolution, different kinds of fossils occur in rocks of different ages, enabling geologists to use fossils to understand geological history. For geologists, fossils are one of the most important tools for age correlation.
How do scientists explain the existence of fossils of the same plants and animals on continents that are separated by vast ocean or that are thousand of kilometers apart?
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.
What caused continental drift?
The causes of continental drift are perfectly explained by the plate tectonic theory. The earth’s outer shell is composed of plates that move a little bit every year. Heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle.
Which statement explains what similar fossils found on distant continents suggest about Earth’s history?
Which statement explains what similar fossils found on distant continents suggest about Earth’s history? The continents have moved over time.
Which explanation provides support for continental drift theory dinosaurs lived on many continents?
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 did Wegener notice about fossils on different continents?
In the early 1900s, the German scientist Alfred Wegener noticed that the coastlines of Africa and South America looked like they might fit together. He also discovered evidence that the same plant and animal fossils were found along the coasts of these continents, although they were now separated by vast oceans.
Which two pieces of fossil evidence support the idea of continental drift quizlet?
Each fossil supports this idea because they were found on different continents. What three key evidence supports continental drift? Fossil clues, plants, rock clues and climate clues were discovered on the different continents.
