Figure 9. Comparison of fossil and extant pomatostomid wing bones. (A–B) distal left humerus of Pomatostomus sp. QM F30358 and (C–D) distal right humerus of P. temporalis AM O.65103 (mirrored). Right ulnae of (E–F) Pomatostomus sp. QM F57939 and (G–H) P. ruficeps AM O.60045. (A,C,F,H) caudal aspect; (B,D,E,G) cranial aspect. Some characteristic features of Pomatostomus shown: 1, proc. supracondylaris dorsalis long and bifurcated; 2, sulcus humerotricipitalis very shallow; 3, distal end of humerus well expanded ventrally; 4, distal extent of proc. flexorius much greater than that of condylus ventralis; 5, condylus ventralis long with respect to length of condylus lateralis; 6, olecranon short; 7, distal edge of proc. cotyla dorsalis about level with that of cotyla ventralis; 8, cotyla ventralis shallow; 9, impressio m. brachialis very shallow; 10, shallow depression situated distally of attachment scar for trochlea humeroulnaris. Scale bar = 2mm.
