New finding of Mesozoic ephippia of the Anomopoda (Crustacea: Cladocera)

Fossil Mesozoic anomopods (Crustacea: Cladocera) have only been found twice previously, although this group apparently differentiated in the Palaeozoic. This paper describes the finding of anomopod ephippia of three different types in the locality Khutel‐Khara, Mongolia (Lower Cretaceous, 129±9 Mya). This discovery demonstrates once more that the idea of rarity of cladocerans in Mesozoic fossils was motivated by insufficient attention of carcinologists to such fossils.
