| 摘 要： | 根据新材料，对始无齿翼龙的特征进行了修订：中部颈椎体没有神经棘；肱骨三角嵴的长度与肱骨长度之比率约为0．2．5：翼掌骨的长度与第二翼指骨的长度几乎相等；第二翼指骨与第一翼指骨的长度之比率约为0．76。始无齿翼龙的新标本与正型稍微不同，可能由个体发育所引起。

| Abstract: | The diagnostic features of Eopteranodon are amended on the basis of new material. The amended features are as follows: the neural spines in the mid cervical vertebrae are absent; the ratio of the length of the deltopectoral crest to the humerus length is approximately 0.25; and the length of the metacarpal Ⅳ is almost equal to the length of the second wing phalange; the ratio of the length of wing phalange 2 to wing phalange 1 is approximately 0.76. The new specimen of Eopteranodon is slightly different from its holotype, probably due to ontogenetic development. |
