摘要
根据不完整的化石骨架,建立船颌翼龙一新属新种:李氏凤凰翼龙。它产自辽西中侏罗世的髫髻山组。具有以下特征:上颌有11对以上牙齿,最后一枚牙齿位置靠后,位于眶前孔后下角的下方。翼掌骨长度大约为肱骨的55%。凤凰翼龙的发现不但增加了船颌翼龙的新成员,而且对船颌翼龙的古地理分布提供了重要信息。它代表目前为止最早的船颌翼龙类。为我们了解船颌翼龙的起源和演化具有重要意义。
A new scaphognathine pterosaur：Fenghuangopterus lii gen.et sp.nov.is erected based on an incomplete skeleton.It comes from the Middle Jurassic Tiaojishan Formation of the western Liaoning.It is characterized by more than 11 pairs of the upper jaw teeth,and the last tooth is located far posteriorly in the jaw,under the postoventral corner of the antorbital opening,metacarpal IV length is about 55% that of the humerus.The discovery of Fenghuangopterus not only adds a new member of scaphognathine pterosaurs,but also provides much more information on the paleogeographical distribution.It represents the earliest scaphognathine pterosaur known.It plays a key role in understanding the origin and evolution of scaphognathine pterosaurs.
