It probably resembled a cross between the Secretary Bird and Crested Caracara , and lived during the Early Miocene 23&ndash 16 million years ago . Its remains were found in Riversleigh Queensland , Australia . The Flexiraptor is only known from a tibiotarsus ankle bone . However, this is of most peculiar construction, allowing the leg to be swiveled backwards and sideways. The bird was thus well adapted to reaching into holes and crevices and extracting prey. The vernacular name Flexiraptor was coined to reflect this ability. References Boles, W.
