摘要：来自特拉华州北部 Merchantville 组（早坎帕世，晚白垩世）的翼龙颈椎、肱骨碎片以及相关的股骨和胫骨提供了北美东部白垩纪飞行爬行动物的第二个记录。这些骨头在形态和大小上类似于无齿翼龙，但不能确定地归属于鸟足科的特定属。与来自堪萨斯州 Niobrara Chalk 的无齿翼龙骨骼进行比较表明，特拉华翼龙的翼展约为 5.8 m（19 英尺）。切萨皮克和特拉华运河沿岸的 Merchantville、Marshalltown 和 Mount Laurel 地层的连续上白垩纪爬行动物动物群首次被列出。
ABSTRACT A pterosaurian cervical vertebra, fragment of humerus, and associated femur and tibia from the Merchantville Formation (early Campanian, Late Cretaceous) of northern Delaware provide the second record of Cretaceous flying reptiles in eastern North America. These bones resemble Pteranodon in morphology and size but are not securely assignable to a particular genus of the family Ornithocheiridae. Comparison with Pteranodon skeletons from the Niobrara Chalk of Kansas indicates a wingspan of about 5.8 m (19 ft) for the Delaware pterosaurs. The successive Upper Cretaceous reptile faunas of the Merchantville, Marshalltown, and Mount Laurel Formations along the Chesapeake and Delaware Canal are listed for the first time.
