摘要
对冠斑犀鸟的骨骼系统进行了详细的观察和描述,其头骨厚重、骨壁坚硬;颌骨、前颌骨极度前伸,构成巨大的上喙,其后部连同鼻骨向背方显著隆起,构成盔。寰椎、枢椎、尾综骨、胸骨等形态特殊。跗跖骨结构以及足趾近、远端趾节的长度反映了明显的树栖性特征。
The skeletal system of Oriental Pied Hornbill (Authracoceros albirostris) was described, and compared with that of other species. The skull is thick and firm; the maxilla and premaxilla extend forward extremely, making up of the huge upper beak ; the posterior part of the beak and the nasal protrude dorsally forming a large casque. It is also peculiar in the morphology of atlas, axis, pygostyle, sternum, etc. Additionally, the structure of tarsometatarsus and the pedal digits presents obviously arboreal adaptation.
