Decapod crustaceans have played a vital role in marine ecosystems since the Mesozoic Era. They have been increasingly studied in terms of taxonomy, phylogeny, paleoecology, biodiversity, taphonomy, and macroevolution over the last decades by both professional and avocational paleontologists. To date, more than 4200 species are known from the fossil record. Every three or so years since the year 2000, crustacean paleontologists from around the world get together for the Symposium on Fossil Decapod Crustaceans. This conference, also open to other crustacean research, has been important in catalyst for scientific research and a place to reconnect with or make new friends and colleagues. A subsequent conference proceedings volume has been published for nearly all of the previous symposia. This conference proceedings volume bundles 13 articles about fossil crustaceans, mostly Decapoda, but also Isopoda and Cirripedia. They range in age from the Early Jurassic to the Pliocene, and come from Europe, North America, and South America. Jointly, these articles signify considerable progress in our knowledge of fossil crustaceans.
