This handbook is a completely revised version of the first edition, which was published in 2012. Plant palaeoecologists use data from plant fossils and plant subfossils to reconstruct ecosystems and food economies of the past. This book deals with the study of subfossil plant material retrieved from archaeological excavations and cores dated to the Late Glacial and the Holocene. One of the main objectives of this book is to describe the processes that underlie the formation of the archaeobotanical archive and the ultimate composition of the archaeobotanical record - being the data that are sampled and identified from this immense archive.
