Book Description
Feathers are one of the most unique characteristics of modern birds and represent the most complex and colourful type of skin derivate within vertebrates, while also fulfilling various biological roles, including flight, thermal insulation, display, and sensory function. For years it was generally assumed that the origin of flight was the main driving force for the evolution of feathers. However, various discoveries of dinosaur species with filamentous body coverings, made over the past 20 years, have fundamentally challenged this idea and produced new evolutionary scenarios for the origin of feathers. This book is devoted to the origin and evolution of feathers, and highlights the impact of palaeontology on this research field by reviewing a number of spectacular fossil discoveries that document the increasing morphological complexity along the evolutionary path to modern birds. Also featuring chapters on fossil feather colours, feather development and its genetic control, the book offers a timely and comprehensive overview of this popular research topic.

Book Description
Dinosaurs didn’t die out when an asteroid hit Earth 66 million years ago. Get ready to unthink what you thought you knew and journey into the deep, dark depths of the Jurassic. The discovery of the first feathered dinosaur in China in 1996 sent shockwaves through the palaeontological world. Were the feathers part of a complex mating ritual, or a stepping stone in the evolution of flight? And just how closely related T. rex to a chicken Award-winning journalist John Pickrell reveals how dinosaurs developed flight and became the birds in our backyards. He delves into the latest discoveries in China, the US, Europe and uncovers a thriving black market in fossils and infighting between dinosaur hunters, plus the controversial plan to use a chicken to bring dinosaurs back from the dead.

Book Description
Selected by NPR's Maureen Corrigan and The Wall Street Journal's Tom Nolan as one of the best mysteries of the year, Gazan's The Dinosaur Feather--which the Financial Times called "outrageously entertaining"--is a classic of modern Scandinavian noir. With keenly observed and deeply flawed characters, this scintillating thriller revolves around the controversial and fascinating connections between dinosaur and avian evolution. Biology postgraduate, PhD hopeful, and single mom Anna Bella Nor is just two weeks away from defending her thesis on the saurian origin of birds when her academic supervisor, the highly respected yet widely despised Dr. Lars Helland, is found dead in his office chair at the University of Copenhagen. The police discover a copy of Anna's thesis in the dead man's bloody lap. When the autopsy suggests that Helland was murdered in a fiendishly ingenious way, brilliant but tormented young Police Superintendent Soren Marhauge is called to investigate. As he begins the daunting task of unraveling the knotted skeins of interpersonal and intellectual intrigue among the scientists at the university, his own troubled past begins to complicate the case. Everyone involved with the investigation--from Anna Bella Nor to Helland's numerous academic rivals to Marhauge's own ex-wife, who is pregnant with her current husband's child--has something to hide, muddying the investigation and presenting the detective with the greatest professional and personal challenge of his life.
