The dewacaupo (Murculus deppa) is an extinct flightless bird that was endemic to the island of Madagascar. It was first discovered by indigenous settlers around 1400. It was exploited for its meat and its beak. It was last seen alive in 1563. The genus Murculus is monotypic, containing only the species M. deppa.
Dewacaupo fossils have been found in late Miocene rocks, which date to around 6 million years old.
