What was the lifespan of most dinosaurs?

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 longest carnivore dinosaur?

Spinosaurus
Spinosaurus was the biggest of all the carnivorous dinosaurs, larger than Tyrannosaurus and Giganotosaurus. It lived during part of the Cretaceous period, about 112 million to 97 million years ago, roaming the swamps of North Africa.

How did the dinosaurs live so long?

It is a longstanding mystery why dinosaurs became and remained so plentiful for more than 180 million years. The traditional theory: dinosaurs suddenly replaced other land animals because of special traits that gave them an evolutionary advantage, such as being warm-blooded, nimble and able to occupy varied habitats.

Which animal lives for 500 years?

The ocean quahog is a fist-size clam that can live to be 500 years or older. Some researchers believe the sturdy quahog’s secret to a long life is its ability to protect its proteins from damage.

When did dinosaurs live timeline?

Non-bird dinosaurs lived between about 245 and 66 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous.

How long did the dinosaurs live after the asteroid?

Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.

How far did dinosaurs travel?

It is thought that some dinosaurs may have migrated significant distances, notably those living near the Earth’s poles, where food supplies were seasonal. Suggestions of how far they travelled vary, but one recent study estimated large sauropods might have made an 1,800-mile round trip each year.
