摘要/Abstract

摘要： 大熊猫Ailuropoda melanoleuca(David)是世界闻名的稀有珍贵兽类,仅产于我国的少数地区。由于材料的难得,对大熊猫形态学的研究还不多见。在骨学方面,张鹤宇等(1960)曾记述过颅骨及牙齿的比较解剖,朱靖(1974)曾涉及到幼体牙齿生长的序列。Davis(1964)曾进行过较系统的解剖工作,他的研究材料包括3例完整标本和一些零散骨骼,但缺少完整幼体标本(仅有1例幼体头骨)。

Abstract: This study is based on six complete skeletons of the giant panda,Among them, a juvenile specimen is involved.Besides, theskeleton of black bear, lesser panda, lion, tiger,and dog were used for comparison. Measurements and proportions of the pelvis are given in the table.Examination shows that the pelvis of the giant panda is notably different from that of any other carnivores in fouowing aspects.These are: 1 .theshortening of the pelvis; 2. strengthening of the sacroiliac articulation; 3. the puboischiatic symphysis is greatly shortened; 4 .the obturator foramen is more or less triangular in outline; 5.the ilia lie in the frontal, rather than the sagittal plane; 6 .the increase in the thickness of pelvic bone.
