Abstract A new and articulated specimen of a pterosaur wing including the humerus, radius/ulna, parts of the carpus and metacarpus and a first wing phalanx from Maastrichtian phosphatic deposits of Morocco are assigned to Tethydraco regalis Longrich et al., 2018. Aspect of the humerus morphology, shape of the deltopectoral crest and ratios of the wing elements suggest that T. regalis is an azhdarchid rather than pteranodontian pterosaur, as originally proposed. A high abundance of azhdarchid remains in the open marine setting of the Moroccan phosphates casts doubt on suggestions that Azhdarchidae are largely terrestrial pterosaurs.

来自摩洛哥上白垩纪（马斯特里赫特）磷酸盐的铰接翼龙翼

摘要 来自摩洛哥马斯特里赫特磷酸盐矿床的翼龙翼的一个新的铰接式标本，包括肱骨、桡骨/尺骨、部分腕骨和掌骨以及第一翼指骨，被分配给 Tethydraco regalis Longrich 等人，2018 年。肱骨形态、三角胸嵴的形状和翅膀元素的比例表明 T. regalis 是 azhdarchid，而不是最初提出的翼龙类翼龙。在摩洛哥磷酸盐的开阔海洋环境中，大量的 azhdarchid 残骸使人们对 Azhdarchidae 主要是陆生翼龙的说法产生怀疑。
