First Mesozoic amphipod crustacean from the Lower Cretaceous of SE England

Long predicted but not found, a Mesozoic amphipod is finally reported from the lower Weald Clay Formation (late Hauterivian) of the County of Surrey in Southeast England, UK. Occurring in non-marine Wealden deposits, and sideswimmer-like, this lilliputian is referred to a new senticaudatan collective group and named Gammaroidorum vonki gen. et sp. nov. Future search should focus on finer-grained insect beds to elucidate the history of small, little-known, but significant crustaceans. [Display omitted]
