Abstract:In this study, development and ossification sequence of pectoral girdle and forelimb skeletons of Chinese toad (Bufo gargarizans) tadpole during 33-46 stages were investigated using double staining. The results showed that the pectoral girdle emerged at stage 36, and connected to presacrals Ⅱ, Ⅲ by muscles at stage 39, sternum formed at stage 45 (fig. 1) , chondrification and ossification of pectoral girdle elements began around the glenoid fossa; Emergence and ossification of the forelimb occured in a proximo-distal and postaxial-preaxial direction (fig. 2, fig. 3) . Presence of pectoral girdle and forelimb in anuran alleviate the shock of movement after landing, which reflects the adaption of anuran tadpole transformation from aquatic to terrestrial life in metamorphosis.
