Asperocephalus milleri Ahlberg (nomen nudem)

This porolepiform fish, first named by Per Ahlberg is one of the biggest fishes in the lake and a fierce predator. It is very rare as often is the case with the fish at the top of the food chain. I only show here one of its very sharp and pointy teeth. More work needs to be done on this species.
