Yes. They're called "birds".
no, there was only sand
Of course Yes I hope it helped. xD
That is technically impossible because dinosaurs are extinct and that means that they are gone.
Dinosaurs and mammals coexisted during the Mesozoic era. If you count birds as dinosaurs, then they still coexist now in the Cenozoic.
Yes because when we are not exist yet dinosaurs rule the earth but today there are no dinosaurs here.
No, dinosaurs are neither a hypothesis nor is there a "hypothesis of Earth".
The duration of When Dinosaurs Ruled the Earth is 1.6 hours.
Dinosaurs first appeared in the tertiary stages of the Earth. Tertiary was when the dinosaurs ruled the earth. Then there was jurassic and then creteacious
According to most scientists, we have had virtually the same amount of water on Earth since the planet formed. That would mean that there was the same amount of water on Earth when the dinosaurs existed. However, it is important to note that there is probably an infinitesimal amount more water now then there was in the time of the dinosaurs, simply because of the fact that there have been meteors/meteorites that carried a little bit of water to Earth since the dinosaurs died out.
Actually, there ARE dinosaurs now; birds of all kinds are now classified as dinosaurs. They are actually more numerous than mammals!
No. Today's reptiles lizards, snakes, turtles, crocodiles, and the tuatara are not dinosaurs and, other than crocodiles, are not even closely related to them. Apart from birds, which are now known to have descended from small, carnivrous dinosaurs, dinosaurs have been extinct for millions of years.
Yes, and they still do. Birds are now recognized as the only living dinosaurs. Aside from that, no. Non-avian dinosaurs died out long before the first humans walked the Earth.
