Question

dinosaur animal project points

Answer 1

Dinosaurs walked the earth for over 165 million years.
They lived during a period of time known as the Mesozoic Era, or Age of Reptiles.
At the end of the Cretaceous Period they became extinct – that was around 65 million years ago. During this time there was a great deal of volcanic activity and many earthquakes.
Many people believe that dinosaurs became extinct because an asteroid hit the earth changing the climate dramatically. It is believed that dinosaurs couldn’t adapt to these changes.
The word dinosaur means terrifying lizard. This name was invented by Sir Richard Owen in 1842.
The oldest known dinosaur is Eoraptor, a meat-eater that lived 228 million years ago.
Most dinosaurs hatch from eggs, and they could not fly or live in water.
Dinosaurs are classified as reptiles. They are divided into two groups based on the structure of the hip. One group has lizard-like hips and the other group has bird-like hips.
Most palaeontologists, scientists that study dinosaurs, believe that birds are the only surviving dinosaurs. So dinosaurs aren’t really extinct because their descendants are still living.
