How long could dinosaurs live?
Early estimates of 300-year lifespans for the largest sauropods were based on comparisons with crocodiles and turtles, which have much slower metabolisms. The consensus is now that Apatosaurus and Diplodocus dinosaurs probably only lived for 70 or 80 years, which is about the same as an elephant today.
What is the oldest dinosaur still living?
Nyasasaurus parringtoni is currently the oldest known dinosaur in the world. An upper arm bone and some back bones from Nyasasaurus were first uncovered in Tanzania in the 1930s, but the fossils were not studied closely until recently.
How long did at Rex live?
Tyrannosaurus rex had a life expectancy of about 28 years. Previous studies have suggested that it went through a growth spurt in its teenage years, but until recently, scientists didn't know much about how it grew from a hatchling to a powerful predator.
What killed the dinosaurs?
For decades, the prevailing theory about the extinction of the dinosaurs was that an asteroid from the belt between Mars and Jupiter slammed into the planet, causing cataclysmic devastation that wiped out most life on the planet.
Can dinosaurs come back?
The answer is YES. In fact they will return to the face of the earth in 2050. We found a pregnant T. rex fossil and had DNA in it this is rare and this helps scientists take a step closer of animal cloning a Tyrannosaurus rex and other dinosaurs.
How long did argentinosaurus live?
Argentinosaurus Lived in Middle Cretaceous South America
What makes Argentinosaurus slightly unusual is that it lived at least 50 million years after these more familiar sauropods, in a place (South America) the breadth of whose dinosaur diversity is still unappreciated by the general public.
Is Jurassic world real?
The Jurassic Park franchise — including Jurassic World: Fallen Kingdom, in theaters Friday, almost exactly 25 years after the first movie came out in 1993 — is obviously entirely fictional, so you don't have to worry that the dinos are coming to get you.
Are dinosaurs still alive in 2021?
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.
Which came first dinosaurs or humans?
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.
