. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology; Zoology. v 4M k lAjSfeS f| / 1 mm HHHkVB "imr **». Figure 34. (A) The holotype skull, atlas and associated postatlantal vertebrae of Eocaecilia micropodia (MNA V8066) at the completion of the initial stage of preparation and before removing the skull from the matrix. (B) Enlarged view of the vertebrae after detailed preparation; rostral is to the left. The loss of the left half of the neural arches exposes the right pedicles in medial view, which reveals an internal process on the medial surface of each pedicle (p i p, white arrows). Anteroventral to each process is the internal ostium of the intravertebral foramen (stereophotographs). The loss of the left half of the neural arches of the atlas, axis (PA2), PA4, and PA5 (on PA3 the arch is completely broken away) exposes the internal surface of the neural canal. The medial openings of in- travertebral foramina are evident on all pedicles. Bilaterally, along the pedicle- centrum junctions, the floor of the neural canal of the atlas is excavated by a deep, longitudinal sulcus. The rostral end of the sulcus begins at the transverse level of the medial opening of the intravertebral fora- the sulcus extends caudally to the men; posterior end of the atlantal centrum. The two sulci together compose about two- thirds of the breadth of the neural canal;.
