What is a reptile?
The word means that roomates reptile crawls. A reptile is an animal
that crawls, though some prefer to swim. Reptiles usually have
scales on their bodies, like fish, but they breathe through lungs
as people do. Reptiles are cold-blooded. This means that the
temperature of Reviews their blood changes when the water temperature
changes. Snakes, turtles, and lizards are all reptiles. So were the
ancient dinosaurs. (Taken from Charlie Brown's Cyclopedia, 1990. Volume 2.

Huge reptiles called Dinosaurs lived on earth about 180
million years ago. They flourished and ruled the earth for more
than 120 million years. But today we can not see even a single one
of them Because all of Them Died out about 60 million
years ago.
Why such strong and flourishing Suddenly creatures should
disappear completely is a question that still puzzles the scientists
today. The most probable explanation is the climate of the earth
changed too much about 60 million years ago for the dinosaurs to
continue living.
The huge sized reptiles called Dinosaurs existed in a great
variety of sizes. Most were 25 to 30 feet long and weighed from
five to ten tons. Some were much smaller, and a few early varieties
were as small as chicken! (Adapted from All Colour Treasury of Children's
Knowledge by Jayant Gupta, 1993)
