Angustinaripterus

Angustinaripterus was discovered at Dashanpu near Zigong in the Szechuan province of China. It is known from a single skull.

Angustinaripterus was named in 1983 by He Xinlu. The type species is Angustinaripterus longicephalus. The genus name is derived from Latin angustus, "narrow" and naris, "nostril", combined with Latinized Greek pteron, "wing". The specific name is derived from Latin longus, "long", and Greek kephale, "head".

The holotype, ZDM T8001, is a single skull with lower jaws, found in 1981 by researchers from the Zigong Historical Museum of the Salt Industry, in the Xiashaximiao Formation (Bathonian).

The skull shows large, intermeshing teeth at the tip, and may have been used to snatch fish from the surface of water. The teeth put Angustinaripterus near to Dorygnathus, but some other features of the skull are comparable with those of azhdarchids.
