Retroarticular regions of left mandibles in lateral (left),medial (middle) and dorsal (right) views.Both the left and right mandibles of Asteriornis are shown in dorsal view,as the retroarticular process is only preserved on the left mandible and the medial process is only preserved on the right mandible.Images of Anatalavis are mirrored.
