An anomopod branchiopod crustacean that displays many structural similarities to the extant genera Scapholeberis and Megafenestra (family Daphniidae), fortuitously preserved in amber of Early Cretaceous age, is described. Although most of its appendages have been lost, preservation of several structures is vastly better than in most ‘orthodox’ fossils of these delicate animals. The well-preserved carapace suggests that, like extant representatives of these genera, but in no other daphniid, the animal exploited the surface film, beneath which it suspended itself by means of the straight ventral margins of its functionally bivalved carapace, each of which was armed with a row of close-set setae. Unlike the postabdomen of all the many extant anomopods, which is unsegmented, that of the fossil species, which was well preserved, was segmented; its distal half, or rather more, being clearly divided into four segments. Its topographically ventral margin was armed with pairs of very long spines (relativel...
