Armigatus is an extinct genus of marine clupeomorph fishes belonging to the order Ellimmichthyiformes. These fishes lived in the Cretaceous (Albian to Campanian, about 103-72 million years ago); their fossil remains have been found in Mexico, southern Europe, the Middle East and North Africa, suggesting the genus ranged across the Tethys Sea.

Etymology

The Latin generic epithet Armigatus, means bearer of armor. The specific epithet brevissimus signifies "shortest, smallest".

Description

Armigatus has an osteoglossid-like tooth patch, a large foramen in the anterior ceratohyal and a series of subtriangular dorsal scutes, giving rise to their scientific name.
