Whybrow (1942-2004) a pioneer in the study of the Late Miocene fossils of the United Arab Emirates Peter Whybrow holding the fossil crocodile skull from Shuwaihat, Al Ain Museum, 1989 - 5 - FOREWORD In the arid landscape and climate that now characterise the United Arab Emirates, it is difficult to comprehend that once this country was a land of fertile plains, rather like today's East African savannahs. The plains had large rivers flowing through them, with a wide variety of animals like elephants, horses, giraffes, gazelles, hyaenas, sabre-toothed cats, apes, ostrichs and other birds, on land and, in the rivers, hippopotami, crocodiles, turtles and large fish. Yet six to eight million years ago, during the Late Miocene period, the Western Region of Abu Dhabi looked much like this. The discovery of the fossil bones and landscapes that tell of this ancient past has been the result of nearly twenty years of painstaking scientific investigation, both by fossil experts (palaeontologists) from overseas institutions like the Natural History Museum in London and Yale University, in the United States, and by local bodies like the Abu Dhabi Islands Archaeological Survey, ADIAS, and the Department of Antiquities and Tourism in the Diwan of the Ruler's Representative in Abu Dhabi's Eastern Region. This short book is designed to bring knowledge of those discoveries to a wider audience, and is published to coincide with the inauguration of a special exhibition of some of the larger and more dramatic fossil finds, like the tusk of an elephant that is over two and a half metres long discovered by ADIAS at Ruwais in 2002, as well as the elephant fossils discovered by the Natural History Museum team at Shuweihat in the 1990’s which included a skull, pair of jaws and leg bone. It is our hope that, together, the book and the exhibition will introduce residents of the Emirates, in particular the younger generation, to this fascinating aspect of the country's past. In times such as these, when the United Arab Emirates is developing at a breathtaking pace and is enjoying all of the benefits of modern technology and services, it is appropriate that we should take the time to remember the country's past - for it is from there that we derive our roots, and from there that the environment of today has evolved. Without knowledge of our past heritage, both human and natural, we cannot fully appreciate the benefits of today, and those to come in the future.
