| Abstract: | According to the study, the skull of Pelteobagrus Fulvidraco consists of 126 bones. It has no parietal,opisthotic and subopercular, but the cartilaginous sympletic. There are a series of cone shaped teeth on the vomer, premaxillary and dentary. The maxillary has evolved short sticklike bone to support the barbells. The preopercular and interopercular lose their primary function of protecting the gill, and they articulate solidly with the hyomandibular and quadrate as to powerfully suspend the low jaw to the hyomandihular and gradually to the neurocranium. |
