Can dinosaurs still be alive 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.
Does anything live in the Mariana Trench?
The organisms discovered in the Mariana Trench include bacteria, crustaceans, sea cucumbers, octopuses and fishes. In 2014, the deepest living fish, at the depth of 8000 meters, Mariana snailfish was discovered near Guam. Fish living closer to the surface of the ocean may have a swim bladder filled with air.
What species survived the dinosaur extinction?
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. Frogs & Salamanders: These seemingly delicate amphibians survived the extinction that wiped out larger animals.
What animals are alive today that lived with dinosaurs?

Are there real dinosaurs in our backyard?

What if dinosaurs and their reptilian relatives had survived?
But if their giant marine reptile relatives – the mosasaurs and plesiosaurs – had survived, then dinosaurs might have found it hard to get a foothold. There could also have been other consequences of dinosaurs and their reptilian relatives, such as the flying pterosaurs, not petering out at the end of the Cretaceous.
What happened to the dinosaurs after the big splash?
Some Dinosaurs Survived the Asteroid Impact The great splat of an asteroid that might have wiped out the dinosaurs apparently didn’t get all of them. New fossil evidence suggests some dinosaurs survived for up to half a million years after the impact in remote parts of New Mexico and Colorado.
Could dinosaurs evolve back from the dead?
Jamal Nasir, a geneticist at the University of Northampton in the United Kingdom, said he wouldn’t rule out the idea of dinosaurs evolving back from the dead. In his opinion, evolution isn’t fixed or planned. In other words, anything could happen.
