A new caridean shrimp (Crustacea: Decapoda: Dendrobranchiata) from the Upper Jurassic Solnhofen Lithographic Limestones of Schernfeld (South Germany)
A new genus and species of caridean shrimps, Occultocaris frattigianii nov. gen. et sp., is described from the Upper Jurassic Solnhofen Lithographic Limestones of Schernfeld near Eichstatt (Lower Tithonian, Hybonotum Zone). It differs from other genera of carideans primarily in the armature of the rostrum in combination with the shape of the chelae of the first and second pereiopods.
Yongjicaris zhejiangensis n. gen. n. sp. (Crustacea, Decapoda, Caridea) from the Lower Cretaceous of Zhejiang Province, China
Decapod crustaceans referred to the new genus and new species Yongjiacaris zhejiangensis in the infraorder Caridea Dana, 1852, family Palaemonidae Rafinesque, 1814, were discovered at two different localities in China: the C Member of the Moshishan Formation in Chengtian village (Yongjia County, Zhejiang Province) and the Showchang Formation in Dongkengli village, Showchang Town (Jiande County, Zhejiang Province). The crustaceans are associated with plants, conchostracans and insects. Based upon palynomorphs, plants, and conchostracans, the fossilbearing beds are probably Barremian in age (Lower Cretaceous). It is the second report of freshwater carideans in Mesozoic rocks.
