Type specimen, Cat. No. il Scale = I cm. Palatal view. X \. palatal rim is well dev^eloped before and behind the caniniform process. All three premaxillary palatal ridges are present and prominent. Behind the level of the caniniform process the premaxilla is raised to form a ledge along the suture with the maxilla. The ledge is furnished with several sharp bony tubercles. The palatines are greatly expanded and make contact with the premaxilla. Tuskless dicynodont, Cat. No. 10661 (Fig. 9). Locality: Welgevonden, Fraserburg. The mandible of this specimen has muscle scars on the lateral face of the dentary, which is not expanded to form a ledge. Behind the symphysis the dentaries are built up to form dentary tables (Fig. ga, den. 1.) (Crompton & Hotton, 1967). A deep dentary groove is present on the dorsal edge of the jaw ramus, and is continued forward as a shallow trough onto the dentary table or ledge. It seems probable that a pad of horn, carried in this anterior trough, would have acted against the palatine and adjoining premaxillary-maxillary portion of the palate during retraction of the jaw. Dicynodontidae Dicynodon grimbeeki (Information taken from Agnew, 1959). The palatal rim is well developed in front of the tusks and the palatine does not reach the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
