Eutrichiurides ("true Trichiurus resemblance") is an extinct genus of cutlassfish known from the early Paleocene to the early Oligocene.[1][2]
Taxonomy
Species within this genus include:[3]
- †E. africanus Dartevelle & Casier, 1949 - mid-late Paleocene (Selandian to Thanetian) of Angola (Landana Formation)[4][5]
- †E. delheidi (Leriche, 1908) (type species) - Early Oligocene of Belgium (Boom Clay) (=Trichiurides delheidi Leriche, 1908)[6]
- †E. orpiensis (Leriche, 1906) - Early Paleocene of Morocco & North Dakota, USA (Cannonball Formation), Late Paleocene of Belgium, Early Eocene of England[7][8]
- †E. plicidens (Arambourg, 1952) - middle Eocene (early Lutetian to middle Bartonian) of Alabama, USA (Tallahatta, Lisbon and Gosport Sand Formations), potentially Bartonian of Libya[9]
- †E. goberti Casier, 1944 - Early Eocene of Tunisia (Gafsa-Metlaoui Basin)[10]
- †E. termieri (Arambourg, 1952) - Late Paleocene/Early Eocene of Morocco (Ouled Abdoun Basin)[11][12]
E. delheidi is the only member of this genus known from partial skull elements (including a partial jawbone) instead of only isolated teeth. The former species E. winkleri Casier, 1946 from the London Clay[13] has been moved to its own genus, Macroynis, as an indeterminate trichiuroid, as there is no evidence that it is a member of this genus.[6]
Fossil teeth of an indeterminate Eutrichiurides have been recovered from the high-latitude Eureka Sound Formation of Nunavut, Canada, suggesting that this genus ranged as far north as the Arctic Circle during the Early Eocene Climatic Optimum.[14] Indeterminate teeth are also known from the middle Eocene-aged Shark River Formation of New Jersey,[15] the Early Eocene-aged Khuiala Formation & Cambay Shale of Gujarat & Rajasthan, India,[16][17] the late Eocene-aged Fayum Depression of Egypt,[18] and the Early Oligocene of the Paris Basin of France.[19]
Description
Eutrichiurides species were very similar in form and build to modern cutlassfish, in that they were long and slender, blade-shaped fishes with elongated jaws possessing fangs and needle-shaped teeth.[20]
