''Eutrichiurides'' ("true '' Trichiurus'' resemblance") is an extinct genus of cutlassfish known from the early Paleocene to the early Oligocene. Taxonomy Species within this genus include: * †''E. africanus'' Dartevelle & Casier, 1949 - mid-late Paleocene (Selandian to Thanetian) of Angola ( Landana Formation) * †''E. delheidi'' (Leriche, 1908) (type species) - Early Oligocene of Belgium ( Boom Clay) (=''Trichiurides delheidi'' Leriche, 1908) * †''E. orpiensis'' (Leriche, 1906) - Early Paleocene of Morocco & North Dakota, USA ( Cannonball Formation), Late Paleocene of Belgium, Early Eocene of England * †''E. plicidens'' ( Arambourg, 1952) - middle Eocene (early Lutetian to middle Bartonian) of Alabama, USA ( Tallahatta, Lisbon and Gosport Sand Formations), potentially Bartonian of Libya * †''E. goberti'' Casier, 1944 - Early Eocene of Tunisia ( Gafsa-Metlaoui Basin) * †''E. termieri'' (Arambourg, 1952) - Late Paleocene/Early Eocene of Morocco (Ouled Abdoun Basin) ' ...

Cutlassfish
The cutlassfishes are about 45 species of predatory ray-finned fish in the family Trichiuridae of the order Scombriformes found in seas throughout the world. Fish of this family are long, slender, and generally steely blue or silver in colour, giving rise to their name. They have reduced or absent pelvic fin, pelvic and caudal fins, giving them an eel-like appearance, and large fang-like teeth. Some of the species are known as scabbardfishes or hairtails; others are called frostfishes because they appear in late autumn and early winter, around the time of the first frosts. The earliest known remains of cutlassfish are isolated teeth assigned to ''Eutrichiurides'' from the Danian, Early Paleocene of Morocco, the United States, and Angola, although their affinities are subject to question. The earliest known body fossil of a cutlassfish is a specimen tentatively assigned to ''Anenchelum'' from the Ypresian, Early Eocene of Italy. Classification This list of species follows FishB ...
