We report and illustrate several unpublished fossil specimens of marine arthropods, housed at the Muséum national d'Histoire naturelle in Paris (France) and coming from the Solnhofen and Nusplingen Lithographic Limestones (Late Jurassic, Germany). Notably, we describe specimens of Antrimpos undenariusSchweigert, 2001, Eryma modestiforme (Schlotheim, 1822) and Mecochirus longimanatus (Schlotheim, 1820). Mecochirus forestiSecrétan, 1968 is considered as a junior synonym of Mecochirus longimanatus. A revision of the specimens previously described is also realized. This contribution thus provides new information on the Antrimpos species from the Solnhofen Plattenkalks and gives a complete overview of the fossil marine arthropods coming from these Plattenkalks which are available at the MNHN.
