I have been a lifelong dinosaur enthusiast. At the age of four, I created what my mother has dubbed my “first research paper”: a stack of illustrations of every different species I could find throughout the pages of my many dinosaur books.
I have been a lifelong dinosaur enthusiast. At the age of four, I created what my mother has dubbed my “first research paper”: a stack of illustrations of every different species I could find throughout the pages of my many dinosaur books. I’ve collected dinosaur books throughout my life, and recently I embarked on a search for a very specific sort of tome: a truly comprehensive, informative, encyclopedic collection of all known dinosaurs. Needless to say, a wide variety of dinosaur-themed texts have been available throughout the years, but try as I might, I couldn’t locate any volume that really fit the bill.
Динозавры – одни из самых поразительных животных, когда-либо существовавших на Земле. Появившись в триасовом периоде около 230 млн лет назад, они царствовали на суше в течение последующих юрского (от 201 до 145 млн лет назад) и мелового периодов (от 145 до 66 млн лет назад). За это время динозавры заселили все континенты и породили сотни различных видов, из которых на сегодняшний день открыто более тысячи.
This book brings together a group that has over many years researched various aspects of the evolution and paleobiology of the synapsids. Many of us have collaborated in our research endeavors, and all of us have at some stage shared information and had many hearty discussions about the biology of our distant relatives. The book comprises eleven chapters. The first two chapters provide an introduction to the predecessors of mammals and their relatives, and an assessment of the ancient world in which they radiated. The opening chapter sets the scene, providing a guide of “who” the synapsids were and how they are related to one another. In this chapter, Tom Kemp provides an up to date assessment of the radiation of the synapsids from their earliest pelycosaur members, to the diverse nonmammalian therapsids, and later to the increasingly more mammal-like cynodonts. All this is done from a global perspective <...>
