Life on Earth can be traced back over three billion years into the past. Many examples of the Earths former inhabitants are to be found in rocks, preserved as beautiful and fascinating fossils. The earliest life forms were bacteria and algae; these produced the oxygen that enabled more complex life forms to develop. About 600 million years ago multi-cellular organisms appeared on Earth, some of which could protect themselves with hard parts such as shells. Many of these life forms were readily fossilized and are used to subdivide geological time. Numerous species have evolved and most are now extinct. Lineages can be traced and extinctions explained as a consequence of terrestrial and extra-terrestrial events.Now in a revised, updated and expanded Second Edition Introducing Palaeontology will continue to provide readers with a concise and accessible introduction to the science of palaeontology.

Life on Earth can be traced back over three thousand million years into the past. Many examples of the Earth's past inhabitants are to be found in rocks, preserved as beautiful and fascinating fossils. The earliest life forms were bacteria and algae; these produced the oxygen that enabled more complex life forms to develop. About 600 million years ago multi-cellular organisms appeared on Earth, some of which could protect themselves with hard parts such as shells. Many of these life forms were readily fossilized and are used to subdivide geological time. Numerous species have evolved and most are now extinct. Lineages can be traced and extinctions explained as a consequence of terrestrial and extra-terrestrial events. Lavishly illustrated with photographs and explanatory diagrams Introducing Palaeontology provides a concise and accessible introduction to the science of palaeontology. The book is divided into two parts. The first explains what a fossil is; how fossils came to be preserved; how they are classified; and what information they can tell scientists about the rocks in which they are found. The second part introduces the major fossil groups taking a systematic view from algae and plants, through the numerous examples of invertebrate animals, to the vertebrates and finally to man's ancestors. Technical terms are kept to a minimum and a glossary is provided.

Stratigraphy is the branch of geology which studies rock layers (strata) and layering (stratification). Stratigraphy deals primarily with sedimentary rocks but also embraces layered igneous rocks where layers result from successive lava flows. A common goal of stratigraphic studies is the interpretation of sequences of rock strata, thus understanding the time relationships involved, and correlating units of the sequence with rock strata elsewhere. Nicholas Steno described four principles of stratigraphy in the seventeenth century, including the law of superposition which states that states that, in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence. These ideas still underpin modern stratigraphy which is governed by The International Commission on Stratigraphy. Its primary objective is to precisely define global units (systems, series, and stages) of the International Chronostratigraphic Chart that, in turn, are the basis for the units (periods, epochs, and age) of the International Geologic Time Scale. Stratigraphy has application in many scientific fields, including archaeology, palaeontology and in the search for natural resources. This succinct and accessible introduction to stratigraphy will prove helpful to students and amateur geologists alike.
