238 SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY FIGURE 6.—Coracoids and scapula of Anatalavis oxfordi (holotype BMNH A5922): A-D, right coracoid in (A) ventral view, (B) dorsal view, (c) lateral (external) view, (D) medial (internal) view; E,F, left coracoid in (E) dorsal view, (F) ventral view; G, right scapula in ventral view. Scales in mm. Humeri (Figure 8): The left is complete, lacking a bit of the pectoral crest and has the proximal end somewhat crushed and distorted. The right lacks the distal one-third and is much crushed and obscured by adhering matrix and bone. Radius and Ulna: These are represented only by the distal two-thirds or more of the left radius and ulna. The radius lacks much of the articular end, and the ulna has the internal condyle broken and the distal end obscured by an adhering piece of bone. Carpal Bones: Only the left ulnare (Figure 9) was located and identified. Carpometacarpus (Figure 9): The right is lacking. The left is complete, having been broken and repaired, with a small piece of the major metacarpal missing and the whole element showing some compressional distortion. Alar Phalanges (Figure 9): All phalanges of the major and minor digits of the left wing are present, as is phalanx 1 of the right major digit. The single alular digit is presumably that of the left side as well.

NUMBER 89 FIGURE 7.—Sternum and pelvis of Anatalavis oxfordi (holotype, BMNH A5922): A, left lateral view; B, dorsal view. Scales in mm. FIGURE 8.—Left humeri of Anatalavis. A-C, A. oxfordi (cast of holotype, BMNH A5922) in (A) anconal view, (B) palmar view, and (c) palmar view, at lesser magnification. D, A. rex (paratype Yale Peabody Museum 948), enlarged for comparison with c. The slight differences are mainly due to slightly different rotation of the specimens. Scale bars=l cm. 239
