Tanidromites insignis (VON MEYER, 1857) (Crustacea: Decapoda: Brachyura) from Late Jurassic non-biohermal facies of the Western Tethys (Pieniny Klippen Belt, Western Carpathians, Slovakia)

The first decapod crustacean remains from Late Jurassic limestones of the Pieniny Klippen Belt (Western Carpathians, Slovakia) are recorded. The material originates from a Middle Oxfordian ammonite shell bed and comprises a single dorsal carapace of the homolodromioid crab, Tanidromites insignis, as well as several fragments of chelipeds of unknown affinity which, however, might belong to primitive brachyurans. Although they usually are considered to be bound to reefal structures, all material studied herein is non-related to biohermal facies and, as such, does not represent a typical occurrence.
