Angustinaripterus Longicephalus He, 1983
''Angustinaripterus'' was a basal pterosaur, belonging to the breviquartossan family Rhamphorhynchidae (more specifically within the subfamily Rhamphorhynchinae) and discovered at Dashanpu near Zigong in the Sichuan province of China. Discovery and etymology ''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). Description The skull of ''Angustinaripterus'', of which the left side is severely damaged, is very elongated and flat. The back part is missing; in its preserved state it has a length of ; the total le ...

Pterosaur
Pterosaurs (; from Greek ''pteron'' and ''sauros'', meaning "wing lizard") is an extinct clade of flying reptiles in the order, Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago). Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. There were two major types of pterosaurs. Basal pterosaurs (also called 'non-pterodactyloid pterosaurs' or 'rhamphorhynchoids') were smaller animals with fully toothed jaws and, typically, long tails. Their wide wing membranes probably included and connected the hind legs. On the ground, they would have had an awkward sprawling posture, but the anatomy of their joints and strong claws would have made them effective climbers, and some may have even lived in trees. Basal pterosaurs were insectiv ...
