The length of the atlas centrum, excluding the pyramidal interglenoid tubercle that pro- longs the floor of the neural canal rostrad (Fig. 32A), is mm. An interglenoid tu- bercle, a feature found in salamanders (Francis, 1934), certain microsaurs (Car- roll and Gaskill, 1978, figs. 115, 116), and albanerpetontids (McGowan, 1998), is not known to be present in any Recent gym- nophionan (Wake, 1970). The two condy- lar facets (or cotyles) extend from the ven- trolateral aspects of the interglenoid tu- bercle to the lateral margin of the cen- trum. The dorsomedial part of each condylar facet thus faces ventrolaterally and the lateral part rostrad (Fig. 32B). The anterior width of the centrum measured across the facets is mm. On the ventral surface of the centrum is a distinct notch between the condylar facets; a rounded, median keel occupies the posterior ventral half of the centrum. A small, presumably vascular foramen occurs on the lateral side of the centrum. The posterior end of the centrum (Fig. 32C), excavated by a deep notochordal fossa, is mm wide and mm high. No evidence exists of a diapophysis. MCZ 9169 (Fig. 33A) reveals that the head of the first rib articulated with the.
