Inguza predemersus is an extinct species of penguin. It was formerly placed in the genus Spheniscus and presumed to be a close relative of the African penguin, but after its well-distinct tarsometatarsus was found, it was moved into its present monotypic genus. The known fossils specimens were found in Late Pliocene rocks in a quarry at Langebaanweg, South Africa, meaning that this penguin lived not much less than 5 million years ago.
