Reconstruction of the skull roof of Caerorhachis bairdi, X 2. tures difficult. The tracing of sutures was also hindered by the loss of much of the bone of the anterior part of the table. Re- construction of this area is based partially on impressions of the internal surface of the missing bone. The pattern of the skull table is shown in Figure 3. The postparietals are characterized by posterior lappets, as in Dendrerpeton, that presumably descend onto the occipital surface. These bones are relatively longer and narrower than those in Dendrerpeton. This is presumably a primi- tive characteristic, judging from the condi- tion in other Mississippian temnospondyls such as Greererpeton (Romer 1969) and Pholidogaster (Panchen 1975). The tabu- lars are small and are separated from the parietals by the supratemporals. This is typical of temnospondyls and unlike the condition in anthracosaurs in which the tab- ulars are larger and make sutural contact with the parietals. The area of the pineal foramen is not preserved, although both the anterior and posterior limits of the pari- etals can be determined. The dorsal part of the right squamosal and adjacent skull roof are represented by a natural cast of the in- ner surface. Although the posterior borders of the right tabular and right squamosal are poorly preserved and incomplete, enough of these bones is present to indicate that the existence of a well developed otic notch is unlikely. The quadratojugal is surprisingly large, in marked contrast to that of Dend-.
