| 摘要: |
| 从朱鹮的骨骼形态学观察中，发现朱鹮的全身骨骼薄弱，充气多，不坚实，胸骨退化，胸肌特别发达，这种不谐调性可能是朱鹮的生存适应性降低的原因之一。朱鹮胸廓外形两侧压扁，胸肋、椎肋关节和胸肋胸骨关节活动性大，较为特殊。脊柱C,Th,L,S,Cy部分占总长百分比为53.9,18.7,4.2,3.9,19.2,股骨、胫骨、跗跖骨长三者之比为0.56∶1∶0.65. |

| Abstract: |
| In the anatomic study of nipponiaps skeleton,it is discovered that the
skeleton is primarily consists of pneumatic bone and that its structure is weak.The size
of its sternum is small,while the pectrolis muscle is welldeveloped.This inconsistency
may be one of the causes which lead to the decrease of the nipponiaps amount.The
morphology of nipponiaps throax looks like a plane transverse cone.The articulatio
sternocostalis and articulatio costovertebralis are much flexible.THe percent of each
partps length of spine (C, Th, L, S and CY) is 53. 9, 18. 7, 4. 2, 3. 9 and 19. 2,
respectively.The length ratio of femuro,tibia and tarsometatarsus is 0.86∶1∶0.65. |
