The skull table in MCZ 4342, as in the type, is relatively wider than in C. bohemicus. A separate intertemporal is clearly present in all specimens. As in Chenoprosopus, the anterodorsal notch of the squamosal embayment reaches far forward along the edge of the table to the midpoint of the supratemporal. The latter bone thus forms a significant portion of the dorsal border of the em- bayment. This is distinctly different from the cond

As in Chenoprosopus, the anterodorsal notch of the squamosal embayment reaches far forward along the edge of the table to the midpoint of the supratemporal. The latter bone thus forms a significant portion of the dorsal border of the em- bayment. This is distinctly different from the condition in other temnospondyls possessing embayments in which a posterodorsal process of the squamosal forms much of its dorsal border, severely limiting participation of the supratemporal or completely ex- cluding it from the rim. The posterolateral comer of the right tabular in MCZ 4342 extends to form a blunt, triangular tabular "horn" that projects posteriorly and slightly ventrally. In contrast to the tabular horn of embolomeres (Panchen, 1970), it is not biramous and bears ornamentation on both dorsal and ventral surfaces. Prominent tabular projections, rare in temnospondyls, also occur in Zatrachys\ however, they differ from those in Cochle- osaurus in being posterodorsally curved, attenuated spikes that probably developed in association with the unique spiny orna- mentation festooning the skull.
