When did the mesosaurus go extinct?

They had webbed feet and grew to about 1 meter (3.3 feet) long. The earliest fossil evidence for these animals indicates that they were alive about 300 million years ago, and their species went extinct about 260 million years ago.

How did the Mesosaurus become extinct?

Mesosaurus lived during the early Permian Period, from 299 to around 260 million years ago. They died out before the massive, end-Permian extinction that killed off a large percentage of marine and terrestrial animals. During the Permian, all of the earth's land mass was combined into the supercontinent called Pangaea.

How long did Mesosaurus live?

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.

What killed the mosasaurus?

During the last 20 million years of the Cretaceous period (Turonian–Maastrichtian ages), with the extinction of the ichthyosaurs and pliosaurs, mosasaurs became the dominant marine predators. They became extinct as a result of the K-Pg event at the end of the Cretaceous period, about 66 million years ago.

What do you still wonder about why the fossils of Mesosaurus that once lived together are found in different locations on Earth now?

This means that these plates, and the continents on top of these plates, are moving away from each other. This divergent plate motion explains why the fossil remains of Mesosaurus that were once together are now found on continents thousands of kilometers apart.

When was the Mesosaurus found?

Mesosaurus, (genus Mesosaurus), early aquatic relative of reptiles, found as fossils from the Early Permian Period (299 million to 271 million years ago) in South Africa and South America.

Can a Mesosaurus swim across the ocean?

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.

Was the Mesosaurus a dinosaur?

What Were the Mesosaurs? During early Permian times (280–290 million years ago), life on land included several amphibians and lizard-like animals that were the ancestors of all the dinosaurs, reptiles, and mammals. Mesosaurus was a lizard-like animal that lived in South America and Africa during the Permian Period.

How did the Mesosaurus fossils 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. 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.

Why could Mesosaurus not have swam across the Atlantic Ocean?

Now if the continents were in still their present positions, there is no possibility that the Mesosaurus would have the capability to swim across such a large body of ocean as the Atlantic because it was a coastal animal. Modern day representation of the Cynognathus.

How did Jurassic world get Mosasaur DNA?

They got the DNA from fossils, pay attention to the rest of the discussion. No. Jurassic World had both male and female dinosaurs. Colin confirmed it was a controlled breeding park.

What dinosaurs had 500 teeth?

This bizarre, long-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with more than 500 replaceable teeth. The original fossil skull of Nigersaurus is one of the first dinosaur skulls to be digitally reconstructed from CT scans.

Did mosasaurus eat Indominus Rex?

Jurassic World

The Mosasaur dragged the Indominus Rex to the bottom of the lagoon, killing the hybrid. ... rex, and Blue the Velociraptor, the Mosasaurus beached itself to catch the hybrid in its jaws and dragged it to the bottom of the lagoon, thus killing it.

How did the Mesosaurus move?

It probably propelled itself through the water with its long hind legs and flexible tail. Its body was also flexible and could easily move sideways, but it had heavily thickened ribs, which would have prevented it from twisting its body. Mesosaurus had a small skull with long jaws.

How did Mesosaurus fossils end up on two different continents?

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. ... Students figure out: The South American and African plates moved apart as a divergent boundary formed between them and an ocean basin formed and spread.

Is there a possibility that Mesosaurus from South America could have swam the Atlantic Ocean to reach Africa?

For example, fossils of the ancient reptile mesosaurus are only found in southern Africa and South America. Mesosaurus, a freshwater reptile only one meter (3.3 feet) long, could not have swum the Atlantic Ocean. ... South America and Africa were not the only continents with similar geology.
