What is the Long neck water dinosaur called?
plesiosaur plesiosaur, (clade Plesiosauria), any of a group of long-necked marine reptiles found as fossils from the late Triassic Period into the late Cretaceous Period (215 million to 66 million years ago).
What dinosaur has a long neck and flippers?
Elasmosaurids were well adapted for aquatic life, and used their flippers for swimming. Contrary to earlier depictions, their necks were not very flexible, and could not be held high above the water surface. It is unknown what their long necks were used for, but they may have had a function in feeding.
Why did Elasmosaurus have such a long neck?
Long necks slow animals down in aquatic habitats, as the neck creates an extra surface that needs to be pushed through the water, and the pressure of the water itself is always trying to push the neck to one side as the animal moves.
Did long neck dinosaurs live in water?
In this view, massive sauropods — four-legged, herbivorous dinosaurs — spent their lives buoyed by seas and swamps. They used their long necks to dive for aquatic plants and to raise their heads out of the water to breathe.

Where Did Elasmosaurus Live? This genus lived during the Late Cretaceous Period and became extinct during the K-T mass extinction approximately 65 million years ago.
Are underwater dinosaurs still alive?
Thought to have gone extinct 65 million years ago (along with the mass extinction of dinosaurs), the coelacanth (pronounced SEEL-uh-kanth) was rediscovered in 1938. The coelacanth is predicted to belong to a lineage that has been around for 360 million years and it is a fish unlike many others.
Did the Brontosaurus swim?
The scientists conclude that there is no convincing evidence of Sauropods swimming. The trackways do not provide clear evidence of Sauropods going for a swim. All is not lost for those who believe that these animals were at home in the water.

What are marine dinosaurs called?
Pre-historic marine reptiles are mainly divided in to two types: the Ichthyosaur and the Plesiosaurs. The Plesiosaur. These creatures had flippers. Some species had long necks and others had short necks. They came out on to the land to lay eggs, like turtles do, and maybe looked like a swimming dinosaur.
Did Elasmosaurus lay eggs?
Moreover, their paddles were rigid and were so specialized for swimming that they would no be able to come on land and lay eggs. Like modern sea snakes, the Elasmosaurus most likely gave birth to live young.
How did the Elasmosaurus breathe?
It was a reptile. It did breathe air. Their necks were so long they wouldn't have been able to lift more than its head above the water. They lived during the Late Cretaceous period 80.5 million years ago.
What killed Elasmosaurus?
Elasmosaurus lived in the seas during the Late Cretaceous period 80 – 65 million years ago. It died out with the dinosaurs and other prehistoric marine reptiles at the end of the Cretaceous.
