Lightning strikes, and strange bird flies into a cavernous museum full of dinosaur skeletons and transforms them back into living creatures.

The enormous beasts then stalk through a vast empty landscape until one of them swallows the bird and they begin to revert to their former skeleton selves.

With a sound basis in science, wonderfully swooping perspectives and rich greeny-brown oil-paint shades, this time-travel book brilliantly evokes a stark pre-historic world.

Winner of the 1995 Caldecott Honor Award.
