Fig. 17. Photographs and line drawings of the palatal surface of M-2989 (A) and M-2958 (B). The paired foramina praepalatinum are exposed ventrally in M-2989, whereas they are concealed by caudal development of the premaxillae on the secondary palate in M-2958. Ventral exposure of these foramina is the most common condition within the SMRS.
