ABSTRACT. Lower Eocene fossil fish material from the Thies Formation in the region of Bargny near the Cap-Vert peninsula, Senegal, reveals predator-prey interaction between two scombrid fishes, the first ever described in the fossil record for the clade. The material is a part and counterpart concretion preserving nearly complete skulls of both predator and prey in 3-dimensions. The larger, predator-fish is here proposed as the second specimen of †Auxides huberti, the only non-Tethyan representative of †Auxides. The smaller, prey-fish is a new genus and species, †Eoscomber senegalicus, closely resembling Scomber. Evidence that †E. senegalicus gen. et sp. nov. was swallowed includes the presence of several of its caudal vertebrae obscured near the area of the opercle of †A. huberti and continuing into its pharynx. Additionally, the skull of †E. senegalicus. is partially enclosed within the abdominal ribs of †A. huberti. †Auxides huberti is the only species of †Auxides recovered with serrated pelvic fin spi...
