Rapa Nui Rail (Rallidae gen. & sp.)
This taxon is known from a single bone that was excavated from archeological deposits on the island of Rapa Nui.
The remains cannot be assigned to any known genus and are of course to scarce for a proper description, yet they show that the island was originally inhabited by at least two different rail species.
