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