Pengana

Extinct genus of birds

Pengana, also referred to as flexiraptor, is an extinct bird of prey that lived during the late Oligocene in what is now Queensland, Australia. It is known only from a fragment of the tibiotarsus that was collected from the Riversleigh World Heritage Area. The tibiotarsus is unusual in that it allowed for the leg to be swivelled backwards and sideways, making it well adapted to reaching into holes and crevices and extracting prey. The genus is only known from a single species, Pengana robertbolesi.
