Ferruaspidae

Ferruaspis (from Latin ferrum, meaning "iron", referencing its preservation in goethite, and Greek aspis, meaning "shield", a common suffix for fossil fish genera) is an extinct genus of freshwater osmeriformray-finned fish from the Miocene of Australia. It contains a single species, F. brocksi, and is the only member of the family Ferruaspidae. It was closely related to the extant Southern Hemisphere smelts in the family Retropinnidae. It is named after professor Jochen Brocks of the Australian National University.
