Background: Factors in Dinosaur Survival Variables such as temperature, food sources, and oxygen levels are all factors that might impact dinosaur survival. Because dinosaurs lived in much warmer climates millions of years ago, many experts doubt they could even survive today.
In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.
It's likely that, with a preponderance of dinosaurs remaining on our planet, humans and many other mammals would not have had the chance to evolve into existence. “Even though mammals thrived in the shadow of the dinosaurs, they did so at small size,” writes Switek.
Just like you're a direct descendant of your grandparents, birds are the only remaining direct descendants of dinosaurs. But I suppose what you're really asking is whether dinosaurs like Tyrannosaurus or Triceratops could ever exist again. Although that would be fascinating, the answer is almost definitely no.
According to new research, dinosaurs would have lived on Earth for many more years, if a huge asteroid hadn't smashed into the planet and wiped them out.
They would still probably be small, scrawny, and very generalized. But instead, the mammals were able to evolve and diversify and, well, ultimately, millions of years later, become some humans. So perhaps we would not have been here if it weren't for this extinction event 65 million years ago.

Yes, birds are the closest living relatives of the dinosaurs because of several shared characteristics: Lay eggs: Like birds, dinosaurs built nests in which to lay eggs. Their young would hatch from these eggs. This way of reproduction is called oviparity.
So, it's not currently scientifically possible to bring back a dinosaur.
It is therefore entirely possible for prehistoric genetic material to survive for up to one million years. But the big dinosaurs departed this life some 66 million years ago. So the prospect of finding enough viable DNA material in what remains of them today is therefore vanishingly remote.
The Permian is a geological record that began nearly 300 million years ago, almost 50 million years before the Age of the Dinosaurs. During the Permian the first large herbivores and carnivores became widespread on land. The Permian ended with the largest mass extinction in the history of the Earth.
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.
It is believed that due to the combination of slow incubation and the considerable resources needed to reach adult size, the dinosaurs would have been at a distinct disadvantage compared to other animals that survived the asteroid that struck Earth 66 million years ago.
Dinosaurs of the northern mid-latitudes (45 degrees north of the equator) experienced average summer temperatures of 27 degrees Celsius (about 80 degrees Fahrenheit). Winters were roughly 15 degrees C (59 degrees F). This is both warmer—about two degrees—and more volatile than late Cretaceous calculations proclaimed.
There are later descriptions of creatures in the Bible that could be referring to dinosaurs. One example is the behemoth of Job 40:15-19. Even in fairly modern history there are reports of creatures which seem to fit the description of dinosaurs.
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
Dig up a fossil today, and any dino-DNA within would have long since fallen apart. That means, as far as scientists know, and even using the best technology available today, it's not possible to make a dinosaur from its DNA.
The oldest DNA fragments recovered are only 800,000 years old, so dinosaur cloning is probably impossible. True cloning also requires an intact, living cell and it has only ever been successful using a host animal of the same species. That rules out mammoth cloning too.
It's not possible to bring back the dodo, even if it becomes possible to build a bird with a dodo genome. Beyond behavior, the dodo proxy must survive in a world that is significantly different from that of more than 300 years ago, when the dodo went extinct.
Around 240 million years ago, during the Cretaceous period, the earth looked pretty different. It was a time when dinosaurs roamed freely and crocodiles coexisted alongside them. In fact, crocodiles are one of the only animals that are thought to have survived the asteroid that wiped out the dinosaur population.
Not all dinosaurs died out 65 million years ago. Avian dinosaurs–in other words, birds–survived and flourished. Museum scientists estimate that there are more than 18,000 bird species alive today. A variety of other species also survived on land, including frogs, snakes, lizards and mammals.
Oldest living creature on Earth identified, emerging 700 million years ago. Scientists have announced that the oldest living creature on our planet is a jellyfish-like organism called a ctenophore. It evolved from the same primordial animals that humans did.
Tardigrades have been around a long time.
Fossils date their existence on Earth to more than 500 million years ago. This means tardigrades have survived the planet's last five mass extinction events. They owe their longevity to some special characteristics.
Humans' ancestors survived the asteroid impact that killed the dinosaurs, shows fossil record analysis.
The risk of humanity extinction by giant asteroid impact is addressed. A 100 km sized asteroid impact may transform the Earth into an inhospitable planet, thus causing the extinction of many life forms including the human species. The exact reason for such a result remains nevertheless uncertain.
