Figure 1: Micro-Computed Tomographic Reconstructions (IMAGE) University of Missouri-Columbia Caption Three-dimensional micro-computed tomographic (μCT) reconstructions and osteological photographs of condylar cranial joints in American alligators. (a) Three-dimensional CT reconstruction in an adult alligator in left lateral view (b) close-up of the white box in (a) shows the three condylar joints of interest. (c) Caudal view of left quadrate shows osteological correlates of jaw joint capsule; (d) rostral view of left quadrate showing osteological correlates of jaw joint capsule; (e) dorsal view of left articular showing articular surface of jaw joint; (f) dorsolateral view of the left otic process of quadrate; (g) dorsal view of left otic process of quadrate showing the articular surface; (h) ventral view of left squamosal showing the shallow cotyle for the otic process; (i) ventrolateral view of left capitate process of laterosphenoid showing articulation with postorbital; (j) dorsal view of left capitate process showing the articular surface of laterosphenoid; (k) ventral view of the left postorbital shows the shallow cotyle of the LS-PO joint. Specimen numbers: MUVC-AL721 in (a,b); MUVC-AL806 in (c-h) and in (k); MUVC-AL008 in (i); MUVC-AL 805 in (j). ca, caudal; cc, calcified cartilage; co, cotyle; do, dorsal; ficps, fibrous capsule scar; fl; fulcrum; la, lateral; me, medial; ro, rostral; scb, subchondral bone; sf, siphonium foramen; ve, ventral.
