What Could Explain The Distribution Of Mesosaurus Fossils?
What could explain the distribution of Mesosaurus fossils? South America and Africa were once part of Pangaea before it was separated into the continents. … Yes, because fossils were found in only two regions that are now separated by the Atlantic Ocean.
What is the distribution of Mesosaurus?
These fossils were found in only two regions, southern Africa and the southern part of South America. The shaded areas on the map show where fossils of Mesosaurus have been discovered. This distribution is a curious one—only two regions far from each other and separated by the Atlantic Ocean.
How does the distribution of the Mesosaurus fossils provide evidence for continental drift?
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. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
What might we infer about the environment in which Mesosaurus lived?
Mesosaurus lived in freshwater lakes and ponds. Elongated and slim, it measured about 1 metre (3.3 feet) long. The skull and tail were both long and narrow, and the animal probably undulated through the water as it fed on small crustaceans and other prey with its jaws, which were full of long, thin, pointed teeth.
Where Mesosaurus fossils are found?
southern Africa
Mesosaurus fossils are found today in rocks in southern Africa and eastern South America. Back in the Permian those two locations were jammed against each other as part of the southern half of Pangaea called Gondwana, so the living range of Mesosaurus did not span an entire ocean.Sep 12, 2021
What is the land like where Mesosaurus fossils are found quizlet?
What is the land like where the Mesosaurus fossils are found? The fossils are found in both South America and Africa, about 4,000km apart. Why are fossils of speices that once lived together found in diffent locations on Earth now? The plates can move causing landmasses to move apart from each other.
How the Mesosaurus fossils get separated?
How did the Mesosaurus fossils on the South American Plate and African Plate get so far apart? Earth’s plates travel at a rate too slow to be experienced by humans. It takes a long time for Earth’s plates to travel great distances. The Mesosaurus fossils moved apart gradually over tens of millions of years.
What is distribution of fossils?
Fossils are found in Australia, South Africa,South America, India and Antarctica. When the continents of the southern hemisphere are re-assembled into the single land mass of Gondwanaland, the distribution of these four fossil types form linear and continuous patterns of distribution across continental boundaries.What is the land like where Mesosaurus fossils are found?
Chapter 1: What is the land like where Mesosaurus fossils are found? Students figure out: The Mesosaurus fossils are found in hard, solid rock on two different plates of Earth’s surface: the South American and African plates. Earth’s outer layer is made of hard, solid rock, and divided into sections called plates.
Why was Mesosaurus a significant piece of evidence that supports plate movement?
Mesosaurus was significant in providing evidence for the theory of continental drift, because its remains were found in southern Africa, Whitehill Formation, and eastern South America (Melo Formation, Uruguay and Irati Formation, Brazil), two widely separated regions.What does the presence of Mesosaurus fossils tell about the initial location and positioning?
The Mesosaurus fossils tell us that South America, Africa and Antarctica were once connected because it is impossible for these reptiles to swim over the vast oceans and move from one continent to another.
Why are Mesosaurus fossils found on continents that are now thousands of kilometers and an ocean apart?
As you determined in the previous lesson, there is a divergent plate boundary between the South American Plate and African Plate. … This divergent plate motion explains why the fossil remains of Mesosaurus that were once together are now found on continents thousands of kilometers apart.
Where did they find fossils of the Mesosaurus And why is that so curious?
The fossils of this prehistoric reptile have been discovered in eastern South America and southern Africa, and since Mesosaurus lived in freshwater lakes and rivers, it clearly couldn’t have swum across the expanse of the southern Atlantic Ocean.What is Mesosaurus in your own understanding?
Definition of Mesosaurus
: a genus of small aquatic presumably fish-eating Permian reptiles of South America and southern Africa.
Which statement best explains why these freshwater Mesosaurus fossils are found today in some rock layers in both South America and Africa?
Which statement best explains why these freshwater fossils are found today in some rock layers in both South America & Africa? The remains of Megasaurus were carried across by predators.
How did the Mesosaurus fossils on the South American plate and the African plate get so far apart?
How did the Mesosaurus fossils on the South American Plate and African Plate get so far apart? Earth’s plates travel at a rate too slow to be experienced by humans. … The Mesosaurus fossils moved apart gradually over tens of millions of years.
How do Mesosaurus fossils support the past existence of Pangaea?
Mesosaurus fossils support Pangaea because the reptile was a freshwater and land reptile and fossils of the creature were found in South America and Africa so it couldn’t cross the by water. … For example, fossils of warm weather plants were found in Spitsbergen in the arctic ocean.
Why are fossils of species that once lived together found in different locations?
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.
What is the theory of moving lithospheric plates?
The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.
What have scientists found out about how fossils are distributed?
Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. … This distribution of fossils led to theories that the southern continents were once joined in a supercontinent called Gondwana.What do you observe with the distribution of fossils across different continents?
More Fossil Evidence
As well as linking Africa to South America, the distribution of fossils suggests that other continents were once contiguous with each other. … This indicates that Glossopteris lived at a time when all of these continents were joined in a single super-continent, which geologists refer to as Pangaea.
What do glacial deposits suggest about plate movement?
The findings suggest that sediment lubrication controls the rate at which Earth’s crust grinds and churns. Sobolev and Brown found that two major periods of worldwide glaciation, which resulted in massive deposits of glacier-scrubbed sediment, each likely caused a subsequent boost in the global rate of plate tectonics.
Who studies the distribution of fossils and minerals in the earth’s crust?
20. A geologist studies the : A) distribution of fossils and minerals in the earth’s crust.
How does coal distribution and glacial evidence support the theory of continental drift?
There is also much climate evidence supporting continental drift, most notable of which is glacial activity. … If the continents are set adjacent to one another at the south pole, these striations line up with each other. This aided Wegener’s theory that the continents were once all joined as a single landmass.Which two continents contain fossils of Mesosaurus an extinct reptile in similar regions of Pangaea?
Answer: Africa and South America.
What type of rock is Mesosaurus?

How does the distribution of Mesosaurus fossils provide evidence for continental drift?
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. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
Why was paleomagnetism so important in discovering plate tectonics?
Paleomagnetists led the revival of the continental drift hypothesis and its transformation into plate tectonics. … Paleomagnetic data continues to extend the history of plate tectonics back in time as it can be used to constrain the ancient position and movement of continents and continental fragments (terranes).What kind of creature was the Mesosaurus?
Mesosaurus was a lizard-like animal that lived in South America and Africa during the Permian Period. Mesosaurus is considered one of the earliest aquatic relatives of reptiles and mammals [1].
What does the presence of these fossils tell of their initial position in early times Brainly?
The glossopteris fossils reflects the evidence of separation of continents like southern Africa, Australia, India and Antarctica which was largely separated by huge and wide ocean which was larlier connected with each other.
Is the presence of animal fossils tells the South America Africa and Antarctica were once connected?
Yes, because these fossils indicated the former connections of the continents before which was called Gondwana in the Triassic period, 200 million years ago.
Where do you think was the Philippines located during the time of Pangaea?
When Pangaea was fully formed, the islands and early precursors of what is now the Philippines were in the Northern Hemisphere.
What is the land where Mesosaurus fossils are found?
Remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America.
