The Upper Jurassic Kimmeridge Clay Formation of the United Kingdom is spectacularly exposed in the sea cliffs of its type locality in south Dorset. It is also seen intermittently through Wiltshire, the home counties, Norfolk and Lincolnshire and in Yorkshire. In Scotland, coeval deposits are seen on both the east coast and on the Isle of Skye.
The Kimmeridge Clay is highly fossiliferous, and the preservation of its fossils is often exceptional. It is common to find ammonites with beautiful iridescence and vertebrates in an articulated condition, with stomach contents. This comprehensive ﬁeld guide, presented in two volumes, reviews all of the major groups, from microfossils to gigantic dinosaurs and pliosaurs. This first volume explores invertebrates, plants and trace fossils, as well as giving a thorough introduction to the sedimentology and collecting from the formation.
