Abstract A new pterosaur, Afrotapejara zouhrii gen. et sp. is described on the basis of a partial rostral fragment from the Cretaceous Kem Kem beds of Takmout, near Erfoud in southern Morocco. The taxon is distinguished from all other Tapejaridae on the possession of a dorsal expansion of the rostral margin a short distance from the rostral tip. Tapejarid features include a downturned rostrum (autapomorphic), edentuly, expansion of the rostral median crest (autapomorphic) and the presence of small foramina on the lateral margins and occlusal surface. The new specimen is the fourth edentulous pterosaur taxon from the Kem Kem beds and is the first unambiguous occurrence of Tapejaridae in Africa.

来自摩洛哥南部 Takmout 的中白垩纪 Kem Kem 床的一种新绦虫(翼龙目,Azhdarchoidea)

摘要 一种新的翼龙,Afrotapejara zouhrii gen。等 sp. 根据来自摩洛哥南部 Erfoud 附近 Takmout 的白垩纪 Kem Kem 床的部分喙部碎片进行描述。该分类群与所有其他绦虫科的区别在于,它的喙缘在距喙尖不远的地方有一个背侧扩张。Tapejarid 的特征包括下翻的嘴(自体变形)、无牙颌、嘴正中嵴的扩张(自体变形)以及在侧缘和咬合面上存在小孔。新标本是来自 Kem Kem 床的第四个无牙翼龙类群,也是非洲绦虫科的第一个明确出现。
