Armigatus is an extinct genus of marine clupeomorph fishes belonging to the order Ellimmichthyiformes.[1] These fishes lived in the Cretaceous (Albian to Campanian, about 103-72 million years ago); their fossil remains have been found in Mexico, Europe, the Middle East and North Africa, suggesting the genus ranged across the Tethys Sea.[2]

Etymology
editThe Latin generic epithet Armigatus, means bearer of armor. The specific epithet brevissimus signifies "shortest, smallest".
Description
editArmigatus 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.[3]
