Few subjects in the Earth sciences are as charming to the public as dinosaurs. The study of dinosaurs stretches our imaginations, gives us new perspectives on time and space, and invites us to discover worlds very dissimilar from our contemporary Earth.
From a technical viewpoint, however, the study of dinosaurs is significant both for understanding the causes of past main extinctions of land animals and for understanding the changes in biological diversity caused by preceding geological and climatic changes of the Earth. These changes are still happening today. A wealth of fresh information about dinosaurs has been learned over the past 30 years, and science's old ideas of dinosaurs as sluggish, clumsy beasts have been completely turned around. This pamphlet contains answers to some often asked questions about dinosaurs, with recent ideas and evidence to correct some long-lived popular misconceptions. Although much has been discovered lately about dinosaurs, there is still a excellent deal more to learn about our planet and its ancient inhabitants.
