Could there be dinosaurs in the ocean?

There are no known aquatic dinosaurs. It would not be impossible for dinosaurs to evolve to live in water (though being air breathers they would not be able to live permanently deep underwater) just as whales evolved from mammals.

Did any big dinosaurs survive?

Survivors. Alligators & Crocodiles: These sizeable reptiles survived–even though other large reptiles did not. Birds: Birds are the only dinosaurs to survive the mass extinction event 65 million years ago. Mammals: After the extinction, mammals came to dominate the land.

Which animal alive today looks most like the dinosaurs?

In fact, birds are commonly thought to be the only animals around today that are direct descendants of dinosaurs. So next time you visit a farm, remember, all those squawking chickens are actually the closest living relative of the most incredible predator the world has ever known!

What dinosaurs lived in the ocean?

The most notable of these reptiles were the ichthyosaurs, plesiosaurs, mosasaurs, and sea turtles. Although they lived at a similar time as dinosaurs, marine reptiles were not dinosaurs since they evolved from a different ancestor.

What is the 2nd biggest dinosaur?

#2 World’s Largest Dinosaurs Ever: Supersaurus vivianae – 112-feet long. Supersaurus is a genus of diplodocid sauropod dinosaur that lived in North America during the Late Jurassic period.

Why didn’t any dinosaurs survive?

Because the dinosaurs were cold-blooded–meaning they obtained body heat from the sun and the air–they would not have been able to survive in significantly colder climates. Yet some species of cold-blooded animals, such as crocodiles, did manage to survive.

How did crocodiles survive dinosaur extinction?

Crocodiles survived the asteroid strike that wiped out the dinosaurs thanks to their ‘versatile’ and ‘efficient’ body shape, that allowed them to cope with the enormous environmental changes triggered by the impact, according to new research. Crocodiles can thrive in or out of water and live in complete darkness.

Did man and dinosaurs exist at the same time?

No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.

What was the last dinosaur that died?

Triceratops
The Triceratops, described in the latest Royal Society Biology Letters, dates to 65 million years ago, the critical period of time associated with the Cretaceous-Tertiary (K-T) extinction event that wiped out all non-avian dinosaurs and many other animals and plants.

Could dinosaurs have survived to the present?

Assuming dinosaurs did make it through to the last few hundred thousand years, and lived alongside humans, could they have survived to the present day? The answer seems to be yes.

Did dinosaurs live on all the continents?

Dinosaurs lived on all of the continents. At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea. During the 165 million years of dinosaur existence this supercontinent slowly broke apart.

What was the climate of a dinosaur’s life?

The sea temperature averaged 37ºC, so even tropical seas today would be too cold for marine life of the time. But land dinosaurs would be quite comfortable with the climate of tropical and semi-tropical parts of the world. That is, until they all died of altitude sickness.

Were there mammals at the time of dinosaurs?

However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs. Many scientists who study dinosaurs (vertebrate paleontologists) now think that birds are direct descendants of one line of carnivorous dinosaurs, and some consider that they in fact represent modern living dinosaurs.
