The fossil of the reptile Mesosaurus was found on both South America and Africa, providing strong evidence for the existence of the supercontinent Pangaea. This freshwater species could not have traversed the vast ocean that separated these continents, indicating that they were once joined. The discovery of such identical fossils on separate landmasses supports the theory of continental drift and the historical connection of continents.

How pangaea theory explains todays position of the continents?
The Pangaea theory posits that all Earth's continents were once part of a single supercontinent called Pangaea, which existed around 335 million years ago. Over time, Pangaea broke apart due to tectonic plate movements, leading to the gradual drift of continents to their current positions. This theory explains the geological and fossil similarities found on different continents, as well as the fit of continental coastlines, supporting the idea that they were once connected. Today, the ongoing movement of tectonic plates continues to shape the Earth's landscape.
How did Wagner use fossil evidence to support his theory for Pangaea?
Alfred Wegener used fossil evidence to support his theory of Pangaea by demonstrating that identical fossil species, such as the freshwater reptile Mesosaurus and the seed fern Glossopteris, were found on continents now widely separated by oceans. This distribution suggested that these continents were once joined, allowing species to inhabit a continuous landmass. Additionally, he highlighted similarities in fossilized flora and fauna across continents, indicating a shared biological history that could only be explained by the existence of Pangaea. This fossil evidence bolstered his argument for continental drift, which was a key component of the Pangaea hypothesis.
Who discover the pangaea?
The concept of Pangaea, the ancient supercontinent, was proposed by Alfred Wegener in 1912 based on evidence from the fit of continents, fossil similarities, and rock formations. He suggested that the continents were once connected and have since drifted apart.
How were the fossil symbols helpful in deciding where to move the continents?
Fossil symbols were helpful in deciding where to move the continents because they provided evidence of past connections between landmasses. Similar fossils found on continents that are now far apart suggest that they were once joined together. By using fossil evidence, scientists could determine the past positions of continents and reconstruct ancient supercontinents like Pangaea.
Wegener's response on fossil plant found in five continents?
Alfred Wegener used the discovery of the same fossil plant species, such as Glossopteris, found on five continents as supporting evidence for his theory of continental drift. He argued that these plants could not have spread across vast oceans, suggesting that the continents were once joined together in a supercontinent called Pangaea. This finding indicated that the continents had since drifted apart, aligning with his hypothesis about the movement of landmasses over geological time. Wegener's ideas were initially met with skepticism, but fossil evidence played a crucial role in strengthening his arguments for continental movement.
Explain the evidence that supports the existence of Pangaea?
Evidence supporting the existence of Pangaea includes: Fossil evidence of similar species found on different modern continents. Rock formations and mountain ranges that match up when continents are rearranged. Paleoclimatic evidence, such as glacial deposits in regions that are now warmer. Similarities in geologic structures and ages of rocks across continents.
Describe evidence that supports the existence of pangaea?
The evidence supporting the existence of Pangaea includes the matching shapes of continents like South America and Africa, similar rock formations and mountain ranges on different continents, and fossils of the same species found on continents that are now far apart. Additionally, the distribution of certain plant and animal species across different continents suggests that they were once connected.
What evidence that supports the existence of pangaea?
There definitively was a Pangaea. Pangaea implies one continent. Back when the earth was forming, there was no oceans, thus the whole earth would be referred to as Pangaea. Today continents would refer to how much land is above the ocean.
What scientific evidence supports the theory of Pangaea?
Scientific evidence supporting the theory of Pangaea includes the fit of the continents' coastlines, similarities in rock formations and geological structures across continents, and matching fossil evidence of ancient plants and animals. Additionally, the distribution of certain species among continents and the discovery of mid-ocean ridges and plate tectonics further support the concept of Pangaea.
What evidence supports the idea of pangaea?
Evidence supporting the idea of Pangaea includes the fitting together of continents like puzzle pieces, matching rock formations and geological structures across continents, similar fossil evidence found on different continents, and the distribution of plant and animal species that suggest they were once connected. Additionally, paleoclimatic evidence such as glacial deposits and ancient climate zones also indicate a time when continents were joined.
How pangaea theory explains todays position of the continents?
The Pangaea theory posits that all Earth's continents were once part of a single supercontinent called Pangaea, which existed around 335 million years ago. Over time, Pangaea broke apart due to tectonic plate movements, leading to the gradual drift of continents to their current positions.

Today, the ongoing movement of tectonic plates continues to shape the Earth's landscape.
What proof did they have that Pangaea is real?
There is no direct proof. But there is evidence best explained by Pangaea having existed. This is the case with a lot of science, and looking for proof is not a very productive way to proceed. Proof works well only in mathematics.
What evidence did alfred wegener find for pangaea?
Alfred Wegener found several lines of evidence to support the theory of Pangaea, including the fit of the continents, similar rock formations and mountain ranges across continents, matching fossil remains on different continents, and similar climates and glacial deposits in areas that are now far apart.
Which fossil occurs on the most landmasses what does this suggest about when these particular continents broke apart?
The trilobite fossil occurs on the most landmasses. This suggests that trilobites were widespread and inhabited different parts of the world before continents broke apart, when the supercontinent Pangaea existed. Trilobites demonstrate how species can be widespread across continents that were once connected.
What does Pangaea and how does it relate to the continents today?
Pangaea was a supercontinent that existed about 335 million years ago. It is believed to have later broken apart into the continents we know today due to the movement of tectonic plates. This theory of continental drift helps explain the similarities in geology and fossil evidence found across different continents.
How did Wagner use fossil evidence to support his theory for Pangaea?
Alfred Wegener used fossil evidence to support his theory of Pangaea by demonstrating that identical fossil species, such as the freshwater reptile Mesosaurus and the seed fern Glossopteris, were found on continents now widely separated by oceans.

What forms of science were used to help gather evidence for the existence of Pangaea?
Geology, paleontology, and paleoclimatology were used to gather evidence for the existence of Pangaea. These sciences helped researchers study the geological formations, fossil records, and ancient climate patterns across different continents to reconstruct the supercontinent Pangaea.
