Melanosomes are the tiny hollows inside hairs or feathers that contain melanin. Melanin is a pigment that gives the black, brown, grey, and ginger colours to hairs and feathers. We were the first ever – or at least the first on record – to have seen evidence of melanosomes in dinosaurs. If we had got it right, this was evidence of the original colour of their feathers. We could say that for the first time we had discovered for sure the colour of a dinosaur.

We live in a golden age of paleontological discovery—on average, we fi nd one new dinosaur species per week. The most fascinating among them take their place in this updated edition of Dinosaurs—The Grand Tour, from Aardonyx, a lumbering beast that formed a link between two- and four-legged dinosaurs, to Zuniceratops, who boasted a deadly pair of horns.

Here, you’ll fi nd everything worth knowing about every dinosaur worth learning about—more than three hundred in all. At-a-glance sidebars put each dinosaur’s diet, size, and where they roamed at your fi ngertips. Stories of harrowing expeditions conjure the thrills of history’s most famous dinosaur hunters. Highlights from recent research reveal what’s new in paleontology today, including scientists’ evolving ideas of what dinosaurs actually looked like. (Hint: They were more colorful—and feathery!—than we thought before.) And illustrations on virtually every page bring these prehistoric creatures to life in all their glory.

Plus, renowned paleontologist Jack Horner contributes “fi eld notes” to help readers set out on their own expeditions—from seeking fossilized footprints at his recommended sites to planning a cross-country road trip using his list of top North American dinosaurs as a map. You’ll learn what it’s like to be part of the most sensational dino-discoveries ever—and maybe make some of your own!

Many problems in engineering geology are fundamentally problems in three dimensional geometry. Spherical projection is a time t€sted technique by means of which complex and arbitrary orientation problems can be solved manually with relative ease. ln spite of rapid developmens in computing hardware, no analytical software has been created which seems capable of adequately replacing spherical projectioo techniques. Therefore, maDy attempts have been made to computerize ihis method. The majority of these attemPts have resulted in programs which are static and inllexible in nature.

The Bergell Alps offer not only a magnificent landscape with impressive mountains that attract many tourists, but also they document a unique geological history, first explored by Bernhard Studer (1851) and since then studied and documented in many publications. In this book, we try to connect visitors with scientific curiosity with remarkable geological features observed in the Bergell Alps, such as a young granite that intrudes into an older stack of nappes (thrust sheets) that represent the European continental plate at the base overthrust by the African plate, causing gradients in temperature and pressure that can be explored by looking at outcrops of rocks in the field.
