Fig. 7. Important anatomical elements of C. microlanius. (A) Ventral view of right vomer showing ridges with teeth, border of the vomeronasal opening, and thickened anterior lateral side with facet for maxilla. (B) Isolated basioccipital in dorsal view showing occipital recess and facets for exoccipital (of the otoccipital) and prootic; about three times as large as the basioccipital next to the sphenoid of the articulated holotype. (C) Right postorbital in anterior aspect with the probable jugal facet identified. (D and E) Ventral views of right (D) and left (E) palatines; note that choanal fossa positioned anteriorly on each bone and two rows of teeth on posterolateral regions. (F to H) Isolated left frontal NHMUK PV R37274 in (F) ventral view showing crista cranii, olfactory canal and facets for the prefrontal and the (presumed) postfrontal, (G) lateral view showing facets for the prefrontal and (presumed) postfrontal, and (H) showing sculptured surface and facets for the nasal and parietal. (I) Isolated left coronoid bone NHMUK PV R37273 in lateral aspect;facets for the dentary, prearticular, and surangular are present as well as the ventral process. (J) Medial view of the same coronoid bone with conspicuous posterior, dorsal, and anterior processes as well as large fossa for the bodenaponeurosis. (K) Right coracoid, medial view, showing coracoid foramen and possible fenestra. (L) Right radius, ulna, carpus, and metacarpus. (M) Dorsal view of isolated sacral vertebrae NHMUK PV R37275 with fused pleurapophysis, foramen sacrale, and neural spine labeled. (N) Close-up of right side of cervical vertebrae showing ribs and pectoral elements including the interclavicle, clavicle, and coracoid with coracoid foramen labeled. Scale bars, 2.0 mm. Images (A) to (E), (K), (L), and (N) are segmented images from the CT scan of the holotype. Abbreviations: As in the Supplementary Materials, p. 48.
