What is "corvitalusoides"

' Corvitalusoides grandiculus ' is an extinct species of songbird, in a monotypic genus of uncertain familial affinities, from the Late Oligocene or Early Miocene of northern Australia. It was described from a distal tibiotarsal fragment found at Riversleigh, in the Boodjamulla National Park of north-western Queensland. The bone size indicates that the bird was among the largest of songbirds, within the size range of ravens and lyrebirds.
