In most cases the descriptions of genera are. Fossils (from Latin fossus, literally "having been dug up") are the preserved remains or traces of animals, plants, and other organisms from the remote past.

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.
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. Although paleontology is concerned with ancient dead materials the relics contain detailed records of organic evolution in relation to environmental conditions.
