Our collective imaginations go wild at the thought of lumbering, ferocious beasts that were so powerful they once ruled the earth. T Rex scares us witless and diplodocus was an astonishing creature of breath taking proportions. It is no wonder then that dinosaur books, especially for children, appeared in the early nineteenth century and are still flying of the shelves today.

Dinosaur exhibitions always draw throngs of people. From the Crystal Palace dinosaurs in London built in the mid 19th Century to the wonderful animatronic models in today's modern museums, these ancient beasts speak to us of a different planet earth, lost in deep time, gone for ever. Yet they have left us bones and teeth that are still revealing amazing facts. Recent science shows most dinosaurs were not cold bloodied reptiles but warm blooded, feathered and colourful. They lived for 160 million years, occupying a warm humid planet rich in vegetation.

When we use the world 'dinosaur' we mean it as a derogatory term for someone who can’t adapt but nothing could be further from the truth. These were supreme rulers that were brought down by an Act of God that defies imagination. So huge was the impact of the meteorite that the earth went cold and dark. Dinosaurs though will never leave us, we will take them with us into the future, in our stories, films and science and we will learn from their old bones ever more details about life on earth, and how even the most successful creatures on earth are, in reality, so fragile.
