These pages are designed as a general guide for all those interested in the fascinating fossils of the British Chalk. Hopefully this will be a useful resource for academics and students alike, whilst at the same time aiding the enthusiastic amateur to identify and understand their finds. The various fossil groups are illustrated (with kind permission) by representative specimens from numerous public and private collections, and the generous assistance of many individuals must be acknowledged. The quality and diversity of Chalk fossils has been recognised for centuries, and a common passion for the formation amongst collectors in the UK has generated vast museum and private collections. The ‘Golden Age’ for Chalk collecting was the 18th and 19th centuries, when numerous large, hand-worked quarries produced many beautiful specimens. Though the turnover for such high quality material is much reduced today, rare and well-preserved specimens can still be found by the persistent collector.
