Reconstruction of the palate of Caerorhachis bairdi, X 2. rerpeton, but no larger than that noted in Other primitive labyrinthodonts such as Edops, Greererpeton or Crossigyrinus (Pan- chen 1973). The jugal cannot be identified. Only a few fragments of the anterior por- tion of the skull roof, of little use in re- construction, are exposed in external view (Fig. 2). Part of the frontal-nasal region is exposed ventrally, but similarly is of little help in the reconstruction of the snout re- gion. The outline of the anterior portion of the skull can be established from the di- mensions of the palate and the length of the lower jaw. Apparently the snout was broadly rounded and the external nares were widely separated. The left maxilla is exposed medially in as- sociation with the skull roof and palatal ele- ments. The right maxilla remains in articu- lation with the margin of the palate (Fig. 5). Neither shows the tooth row in its en- tirety, but there appears to have been room for about 48 teeth in each maxilla. This is the same as the estimated number of maxil- lary teeth reported for Dendrcrpeton. The medial surface of the left maxilla shows large depressions to accommodate the wide bases of the palatine and ectopterygoid fangs. Adjacent to the palatine fangs the" margins of both maxillae appear to be de- void of teeth. Such a condition has not been described in any other labyrintho- donts. The tooth row of the left maxilla is about 10 per cent shorter than that of the.
