DINOSAUR

The dinosaurs were a family of reptiles which lived on the earth millions of years ago. About 400 types of dinosaur have been identified. Dinosaurs ranged in size from about as big as a pigeon to twice the height of a giraffe. It is estimated that dinosaurs lived for between 70 and 130 years, and unusually continued growing for their entire life. The first description of a dinosaur was given in the book 'The Natural History of Oxfordshire' by Dr Robert Plot published in 1677, in which he included a drawing of a thigh bone which he claimed came from a giant man, subsequently it has been identified as the thigh bone of the dinosaur Megalosaurus.
