Idrissia

Idrissia is a primitive genus of the order Stomiiformes, and is an extinct relative of marine hatchetfish and viperfish.^[1] Idrissia's position in the order is in doubt, however, as scientists have not studied enough fossil specimens to determine exactly which stomiiforms the genus is most closely related to.

Idrissia Temporal range: Cenomanian-Early Eocene
I. turkmenica from Turkmenistan
Scientific classification
Kingdom:	Animalia
Phylum:	Chordata
Class:	Actinopterygii
Order:	Stomiiformes
Genus:	†Idrissia Arambourg, 1955

Their fossils are found in regions in northern Africa and Eurasia that correspond to the Tethys Ocean, and range from the Cenomanian epoch of the Cretaceous to the Lower Eocene, when they disappear from the fossil record altogether.

In life, Idrissia species would have had a superficial resemblance to a small-eyed lanternfish or a minnow.
