The present book combines three main aspects: five major mass extinctions; contributions on some other minor extinctions; and more importantly contributions on the current mass extinction. All three aspects are introduced through interesting studies of mass extinctions in diverse organisms ranging from small invertebrates to mammals and take account of the most accepted subjects discussing mass extinctions in insects, mammals, fishes, ostracods and molluscs.

Ashraf Elewa is currently a professor at the University of Minia, Egypt, from where he earned his B.Sc in Geology and his M. Sc. in Lithostratigraphy and Paleontology, and finally his Ph.D. in Micropalentology. His fields of research range from paleontology to traditional and geometric morphometrics and systematics and evolutionary trends in ostracoda.
