. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. A REVISION OF KANGNASAURUS COETZEEI HAUGHTON 297. T\ B Fig. 4. Kangnasaurus coetzeei Haughton. Fragment of a cervical vertebra. A. Ventral view. B. Lateral view. C. Anterior view. Note the prominent ventral keel. Bar scale = 25 mm. anterior and posterior rims of the centrum are strongly scarred, while there is a weak horizontal ridge at about midflank. The ventral surface of the neural canal is perforated by two small foramina at about midlength. The articulated series (Fig. 7) lacks transverse processes and the neural spines are very reduced. Since transverse processes are not lost before the twelfth vertebra in Camptosaurus (Galton & Powell 1980) and Dryosaurus (Galton 1981), they are from the mid-portion of the series. The neurocentral sutures are obsolete, their approximate positions marked by horizontal ridges. The lateral surfaces of the centra are slightly concave while the ventral surface is weakly grooved, giving the centra hexagonal cross-sections at midlength. There are distinct chevron facets. The prezygapophyses are short, with subvertical articular facets, and only just protrude beyond the anterior border of the centrum. The postzygapophyses are naturally much longer, distinctly ridged and grooved (Fig. 7), while there are two shallow dimples on the dorsal surface of the neural arch, just behind the prezygapophyses, a feature also seen in the prosauropod Massospondylus (Cooper 1981, fig. 15C). Ribs A proximal fragment of an anterior dorsal rib (Fig. 9) is the only bone showing any features of note. The capitular pedicel and capitulum are broken off,.
