(2011): Synopsis of fossil decapod crustaceans from Slovakia (Western Carpathians). - N. lb. Geol. Paliiont. Abh., 260: 165-171; Stuttgart. Abstract: In the past only very few works dealt with fossil decapod crustaceans from Slovakia. The systematic research of this group has never been fully conducted there. This contribution provides a short review of all known Mesozoic and Cenozoic fossil decapod occurrences. So far, most of the taxa were described from the Eocene and Miocene strata. Key words: Decapod crustaceans, Slovakia, Mesozoic, Eocene, Miocene. 1. Introduction 2.
