Palaeoapterodytes
Palaeoapterodytes ictus is an extinct species of penguin from the late Oligocene or early Miocene of Argentina, the only member of its genus. Its fossil remains, consisting of only of a severely worn proximal part of a humerus, were found in the Patagonia Formation.
Ameghino named his genus Apterodytes because he mistakenly believed that this species lacked functional wings. In this he seemingly overlooked the effects of taphonomy, and I will simply relay the summation of Lambrecht, as translated from German by Simpson :
Simpson concluded that the meagre remnant assigned to this genus was unidentifiable, and left Palaeoapterodytes to sink into nomen dubium status.
