Skull of the type specimen of Eocaecilia micropodia (MNA V8066) in dorsal view. present during development is rendered moot by the observations of Wake and Hanken (1982: 211), who noted several sources of possible error, in addition to the inclusion of different genera in a "single" growth series. Thus, at best, the evidence for the retention of a quadratojugal vestige in living caecilians is equivocal; yet, there is no doubt that a distinct quadratojugal persisted as the posterolateral marginal el- ement of the dermal skull roof until at least the Jurassic. The large, rectangular nasal, most clear- ly preserved on the left side of MCZ 9169 (Fig. 5), is incised rostrally at the premax- illary articulation. The nasals are missing.
