Eodiaphyodus is a genus of Elopiform fish that is classified in the suborder Albuloidea. It is known from Late Cretaceous sediments across Africa,[1] and it crushed its food with bony plates found in the back of its throat. The type species is E. granulosus and it was named and described in 1952.[2]
The oldest known specimens of Eodiaphyodus were found in Campanian rocks in Angola and Nigeria, and it is believed that the genus originated in this part of Africa before dispersing northwards (via the Atlantic coast of West Africa or via the trans-Saharan seaway) to reach northwestern Africa by the Maastrichtian.
