Dinosaurs first appeared on earth nearly 250 million years ago and survived until a mass extinction event around 65 million years ago. This means that they were dominant animals on the planet for over 150 million years – far longer than human beings. Most scientists believe that the mass extinction of the dinosaurs was caused by a meteor landing on earth.

Did you know that the word museum means a “Temple to the Muses”, all of whom were female? The British Museum in London is a museum of world history, but all too often that history has ignored half of the world. This is true even though women have wielded power in a variety of ways. In ancient Greece, Aristotle believed it was the natural order of things for women to be subordinate to men, that men were more virtuous, brave and intelligent. He also believed that men's blood was hotter than women's blood! Well, on both counts, he was wrong of course.
