Armigatus
Armigatus is an extinct genus of clupeomorph fishes belonging to the order Ellimmichthyiformes. These fishes lived in the Cretaceous (Albian to Turonian, about 103-90 million years ago); their fossil remains have been found in Mexico, Croatia, the Middle East and North Africa, suggesting the genus ranged across the Tethys Sea.[1]

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.[2]
