Dinosaurs were the dominant vertebrate life-form on the planet for 135 million years until they were wiped out, possibly by a bolide impact near the Yucatan Peninsula, 66 million years ago. Their descendants can be found feeding on a bird table near you; meanwhile, they continue to survive in the imagination of children everywhere. For ages 5+.
