Dinosaurs: A Very Short Introduction (Very Short Introductions)
Format: PDF / Kindle (mobi) / ePub
The popularity of dinosaurs seems never ending, as evidenced by the popularity of films such Jurassic Park and documentaries like Walking with Dinosaurs. But how much do these types of entertainment really tell us about recent scientific discoveries and the latest research into the world of the dinosaur?
This is the first book explain how scientists have been able to put together a picture of how dinosaurs looked, what they ate, and how they moved and interacted with each other. Taking a new approach to the subject, David Norman combines different areas of science, such as anatomy, genetics, forensics, and engineering design, to piece together the latest evidence of how animal life evolved on earth. Norman engagingly lays out the history of dinosaur research, from the speculation over ancient myths about dragons, to the latest virtual reality animation sequences and engineering design analysis. He also discusses the role that informed speculation and luck has played in many of the major discoveries.
This book is a fantastic introduction for those just beginning to take an interest in dinosaurs and a must-read for true dinosaur-lovers who want to know not just the latest theories and discoveries, but how scientists achieved them.
seemed to be present in Mongolia in Early Cretaceous times, and the pieces recovered were indistinguishable from the very well known European Iguanodon. This second discovery did not fit at all comfortably with the evolutionary and geographic hypothesis that had been created in the 1984 analysis. Indeed, in more recent years a suite of very interesting Iguanodon-like ornithopods have emerged in Asia, s ur as well as North America, in what can best be described as ‘middle’ Cretaceous times.
different types. There were rocks that appeared to contain no fossils (often referred to as igneous, or ‘basement’). Positioned above these apparently lifeless basement rocks was a sequence of four types of rocks that signified four ages of the Earth. During much of the 19th century these were named Primary, Secondary, Tertiary, and Quaternary – quite literally the first, second, third, and fourth ages. The ones that contained traces of ancient shelled and simple fish-like creatures were
anatomical evidence for a relationship between dinosaurs and birds is now so detailed that it is possible to reconstruct the stages by which a dromaeosaurian theropod might be transformed into an early bird. Early small-sized theropods, such as Compsognathus, have a bird-like appearance – long, spindly legs; a long neck; and fairly small head with quite large, forward-pointing eyes – though they still retain obviously dinosaurian features, such as the clawed hands, teeth in the jaws, and a long,
happen if the prints are buried quickly beneath another layer of mud, because the surface becomes baked hard in the sun, or through the rapid precipitation of minerals that form a kind of cement within the footprint layer. Very frequently, it is possible to deduce from details of the sediment in which the tracks were made exactly what the conditions were like when the dinosaur left its tracks. This can range from the degree to which the mud was disturbed by the feet of the animal and how deeply
