An Introduction to Plant Fossils provides an excellent practical introduction to the study of plant fossils, and is written for those who have had little previous experience of this type of palaeontology. The text summarises the groups of plants occurring as fossils and describes how best to investigate them. It explains modern.

Fossils vary in size from one micrometer bacteria to dinosaurs and trees, many meters long and weighing many tons.
