The late Cretaceous Konservat-Lagerstatten geological deposits of Lebanon are famous for their exceptionally preserved fishes and crustaceans. This book provides the first review of fossil crustaceans in the Cenomanian outcrops (Hakel, Hadjoula, En Nammoura) and the Santonian outcrop (Sahel Alma). The fossils found in these outcrops offer a unique overview of the paleobiodiversity of crustaceans that helps us to better understand the evolution of crustacean clades and the timing of their appearance. Organized by taxonomy and illustrated throughout with species photographs and reproductions of historical illustrations, Fossil Crustacea of Lebanon presents detailed species descriptions of nearly 900 specimens and includes formal descriptions of thirteen new genera and twenty new species across a range of crustacean groups, including Decapoda, Isopoda, Lophogastrida, Stomatopoda, and Cirripedia.
