Kairuku waitaki further differs from K. greb- neffi by the downturned tip of the upper beak, patella with more squared femoral articular surface, tarsometatarsus with mediolaterally wider and less dorsoplantarly deep hypotarsus, and more strongly developed medially oriented flange projecting from plantar-medial corner of trochlea metatarsi II. |
