What did Dolichorhynchops eat?

About Dolichorhynchops

Which means that it probably feasted on squids. After all a squid's body would have been soft enough for this animal to have eaten. However, one of the most interesting facts about Dolichorhynchops is that it eventually went extinct and its evolutionary niche was filled by Mosasaurs.

How were Dolichorhynchops able to fly underwater?

Dolichorhynchops was a short-necked plesiosaur that used long, paddle-like flippers to fly through the water like a penguin. ... Long, narrow jaws filled with 30 to 40 sharp teeth in a single row allowed Dolichorhynchops to grab its prey but not cut it. Instead, the captured fish were swallowed whole.

What is an animal in the modern day that behaves similarly to Dolichorhynchops did in the Cretaceous?

Mosasaurs are ancient relatives of modern-day monitor lizards and snakes. But even the mosasaurs couldn't escape eventual annihilation. All the marine reptiles of the Mesozoic including Dolichorhynchops went extinct at the end of the Cretaceous, along with the dinosaurs.

Where do plesiosaurs live?

Plesiosaurs had a wide distribution in European seas and around the Pacific Ocean, including Australia, North America, and Asia.

Are plesiosaurs real?

Plesiosaurs inhabited the seas from around 200 million to 65 million years ago. They were not dinosaurs, despite living at the same time as dinos. It is thought that plesiosaurs fed mainly on fish, breathed air and laid their eggs on beaches. The largest of these sea monsters reached 15 meters (49 feet) in length.

How did plesiosaurs breathe?

Plesiosaurs breathed air, and bore live young; there are indications that they were warm-blooded. Plesiosaurs showed two main morphological types. Some species, with the "plesiosauromorph" build, had (sometimes extremely) long necks and small heads; these were relatively slow and caught small sea animals.

Can plesiosaur walk land?

The fossil's abdominal cavity contains tiny bones—parts of a plesiosaur that hadn't been born by the time its mother died. ... "Scientists have long known that the bodies of plesiosaurs were not well suited to climbing onto land and laying eggs in a nest [like dinosaurs].

Why did plesiosaurs have long necks?

"A steady neck would be more hydrodynamic than a bent neck, and due to the pressure on a bent neck, plesiosaurs would probably only bend them when moving at slow speeds or when floating,' says Ms Troelsen. ... Several possible theories suggest that plesiosaurs may have developed long necks to extend their feeding range.

Where are plesiosaur fossils found?

Researchers discovered the fossils of the enormous plesiosaur on Antarctia's Seymour Island (known as "Marambio" in Argentina) in 1989.

What's the spitting dinosaur in Jurassic Park?

The poison-spitting dinosaur reconstructed in Jurassic Park is Dilophosaurus. At the time the movie was produced, there was no evidence that this or any other dinosaur spat poison or had poisonous saliva of any kind.

Which dinosaurs lived in the sea?

Spinosaurus is the only dinosaur we know that spent time living in the water. Another dinosaur, Ceratosaurus, could probably swim and catch aquatic prey, such as fish and crocodiles.

How many dinosaurs lived underwater?

Question #14: Were there any swimming dinosaurs? Answer: No dinosaurs were adapted to an entirely aquatic life, although some may have gone into the water to get prey. Baryonyx, for example, was found with fossilized fish scales in its stomach.

Do water dinosaurs still exist?

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.

What dinosaurs are still alive?

Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
