It sinks to the bottom of an ancient river or lake, or is buried in a sand dune. The dinosaur's body rots or is eaten by scavengers, until only its skeleton, or a few bones, remains. Layers of sediment build up over the bones. Minerals collect in the small spaces of the bones, making them harder and heavier. This process turns them into fossils.
The water dries up. Over millions of years, the rock erodes and the fossils are exposed. So many elements can conspire to destroy dinosaur bones and fossils. For example, if the animal died on land, scavengers might have fed on its dead body, leaving the exposed bones to crack and dry up in the hot sun.
And even when the bones were quickly covered by sediments, they could still be destroyed by mountain-building activity, glaciation, or chemicals leaching through the soil.
What Are Trace Fossils? Unlike a regular fossil, which is the actual remains of a prehistoric animal or plant, a trace fossil provides indirect evidence of an organism's existence.
Tracks, burrows, and skin imprints are all trace fossils. The authors state that paleontology is an exciting subject and this is fully borne out by the manner in which they approach the subject. Biologists together with all those interested in the process of organic evolution will find this volume invaluable as it clearly shows the importance of paleontology in understanding modern biology.
Ecologists are currently concerned with evaluating the extent to which products of human activity can influence the degree of variability in modern biological systems. The authors show how the geologic record contains extensive case histories of the effects of natural variability on the process of organic evolution, dispersion of species and their eventual extinction ; the character of past environments including a record of climatic conditions is also preserved in the composition and structure of the sedimentary rocks.
The fossil record may hold the key in order to understand current variability and perhaps help in predicting future changes in defined geographical areas of the world. The description of fossils is clearly of importance to paleontologists; instead of the usual pen drawings species are illustrated by using modern techniques such as stereophotography, X-ray radiography, electron and stereoscan microscopy.
In place of conventional descriptive morphology use is made of mathematical terminology permitting comparisons between such features as shapes, growth rates and functional morphology by statistical treatment, analog-computer simulation and the use of model systems.
Fundamentals of modern ecology are outlined and then considered in terms of ancient environments, e. The importance of phytoplankton in relation to mass extinction of fauna and flora is discussed in terms of ecological factors although it is noted that there is a tendency for mass extinction to follow taxonomic rather than ecologic series. One important aspect of this volume is the manner in which the authors have shown how essential interdisciplinary training is for paleontologists.
An entirely new chapter has been devoted to the origin of the earth and life while an additional appendix describes the main groups of fossils in relation to organic evolution. In keeping with earlier editions chapters are devoted to concise accounts of the major components of geological teaching.
Each subject is placed in perspective with advances in knowledge gained in other disciplines, emphasising links between geology, geomorphology and organic evolution.
Each chapter concludes with a series of facts, concepts, terms, a series of questions pertinent to the contents of each chapter, and a list of suggested further readings. A feature of this book is the descriptive approach to geology, which is amply supported by excellent and clear photographs of geological features together with maps.
Although details involving physics, chemistry and mathematics are kept to a bare minimum, the reader is left in no doubt of their importance in understanding basic geological processes.
For the student of geology it introduces basic concepts; the clarity of presentation provides a suitable text for an introduction to geology for environmentalists, to whom it is highly recommended. Plymouth Great Britain E. Raup and Steven M. Stanley, W.
Freeman and Company, San Francisco, , pp. This book has been prepared for undergraduate teaching in order to provide a conceptual background for studies in paleontology.
This is long overdue for a subject which is often treated in a traditional manner based upon a phylum-byphylum taxonomic format and descriptions of past forms of life preserved in the fossil record. The authors state that paleontology is an exciting subject and this is fully borne out by the manner in which they approach the subject.
Biologists together with all those interested in the process of organic evolution will find this volume invaluable as it clearly shows the importance of paleontology in understanding modern biology.
