When did

When did Dinosaurs went extinct approximately sixty five million years ago (on the give up of the Cretaceous Period), after residing on Earth for approximately a hundred sixty five million years. If all of Earth time from the very starting of the dinosaurs to these days have been compressed into 365 days (one calendar year),

the dinosaurs regarded January 1 and have become extinct the 0.33 week of September. (Using this identical time scale, the Earth could have fashioned about 18.five years earlier.) Using the identical scale, humans (Homo sapiens) were on the earth best considering December 31 (New Year`s eve).

Do any mass extinctions correlate with magnetic reversals?

No. There isn’t anyt any proof of a correlation among mass extinctions and magnetic pole reversals.Earth`s magnetic subject and its environment guard us from sun radiation. It`s now no longer clean whether or not a susceptible

magnetic subject for the duration of a polarity transition could permit sufficient sun radiation to attain the Earth’s floor that it might purpose extinctions. But reversals occur as a substitute frequently–each million years…

Did all of the dinosaurs stay collectively, and on the identical time?

Dinosaur groups have been separated with the aid of using each time and geography. The ‘Age of Dinosaurs’ (the Mesozoic Era) covered 3 consecutive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods). Different dinosaur species lived for the duration of every of those 3 periods.

For example, the Jurassic dinosaur Stegosaurus had already been extinct for about eighty million years earlier than the…

What turned into Pangea?

From approximately 300-2 hundred million years ago (past due Paleozoic Era till the very past due Triassic), the continent we now understand as North America turned into non-stop with Africa, South America, and Europe.

They all existed as a unmarried continent referred to as Pangea. Pangea first commenced to be torn aside whilst a 3-pronged fissure grew among Africa, South America, and North America. Rifting commenced as magma welled up thru…

Did humans and dinosaurs stay on the identical time?

No! After the dinosaurs died out, almost sixty five million years exceeded earlier than humans regarded on Earth. However, small mammals (together with shrew-sized primates) have been alive on the time of the dinosaurs.

Some scientists who examine dinosaurs (vertebrate paleontologists) now assume that birds are direct descendants of 1 line of carnivorous dinosaurs, and a few do not forget that they in truth constitute present day…

Were dinosaurs heat-blooded or cold-blooded?

Scientists have conflicting critiques in this subject. Some paleontologists assume that every one dinosaurs have been ‘heat-blooded’ withinside the identical feel that present day birds and mammals are: that is, that they’d speedy metabolic rates.

Other scientists assume it not likely that any dinosaur should have had a speedy metabolic rate. Some scientists assume that very huge dinosaurs should have had heat our bodies due to their…

Where did dinosaurs stay?

Dinosaurs lived on all the continents. At the start of the age of dinosaurs (for the duration of the Triassic Period, approximately 230 million years ago), the continents have been organized collectively as a unmarried supercontinent referred to as Pangea.

During the a hundred sixty five million years of dinosaur life this supercontinent slowly broke aside. Its portions then unfold throughout the globe right into a almost present day association with the aid of using a process…

Why did a few dinosaurs develop so huge?

Paleontologists do not know for certain, however possibly a huge frame length included them from maximum predators, helped to adjust inner frame temperature, or allow them to attain new reassets of food (a few likely browsed treetops, as giraffes do these days).

No present day animals besides whales are whendidrelease even near in length to the biggest dinosaurs; therefore, paleontologists assume that the dinosaurs’ international turned into much…When did
