Dinosaurs were reptiles that lived 245 to 65 million years ago. Some ate plants, some ate meat, lots ate each other. They are not lizards, even though the name dinosaur means terrible lizard. They could not fly or live in the water (so pterodatyls, plesiosaurs, icthyosaurs, etc were not dinosaurs). They varied greatly in size, some were longer than tennis courts, some were no taller than your knee.
Dinosaurs are big gigantic animals that lived billions of years ago. They were wiped out by a meteorite, but some people believe that most of the dinosaurs were already wiped out when the great mass of rock and ice (meteorite) hit Earth. Dinosaurs transformed into different animals you see today and over the years.
Dinosaurs are prehistoric creatures that got extinct
Renesaurus .............. ;)
Sauropoisedonsuropods.
who knows and cares about dinosaurs and ice cream
I am not totally sure but I think the brontosaurus has the longest neck of all the dinosaurs.
There are no live dinosaurs, the last one died about 65 million years ago. Birds are thought to be their nearest relatives, so it's best to study them instead.
We don't know for sure. The asteroid theory is one example of many theories. Some scientists think one asteroid wasn't enough to kill them all, while others don't think an asteroid killed them at all. We honestly do not know.
