Extinct genus of fishes
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
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.
