Zhejiangopterus is a genus of azhdarchid pterosaur known from one species, which lived in China during the late Cretaceous Period.

 The genus was named in 1994 by Chinese paleontologists Cai Zhengquan and Wei Feng. The type species is Zhejiangopterus linhaiensis. The genus name refers to Zhejiang Province and a Latinised Greek pteron, "wing". The specific name refers to the city of Linhai.

 In 1986 a young chalkstone quarry worker named Xu Chengfa, found a large fossil near the village of Aolicun. Xu by letter informed the director of the Zhejiang Museum of Natural History at Hangzhou, Ming Hua, who from it understood the remains were those of an unknown pterosaur. Therefore he sent a team consisting of the describers and Wu Weitang to investigate. They secured the fossil, instructing the local population to be alert for possible further finds. Xu himself managed to find three more specimens before being killed in an accident in 1988; another worker found a complete skull.

 In the early nineties in total six larger fossils had been recovered from the Tangshang Formation, an 81.5 million year old layer from the Campanian. Among those was the holotype, ZMNH M1330, the impression of the skull of a juvenile individual. Several paratypes were referred: ZMNH M1325, a skeleton lacking the skull; ZMNH M1328, an almost complete skeleton and ZMNH M1329, a fragmentary skeleton.

 Zhejiangopterus was a moderately large pterosaur. Its wingspan was first estimated at 5 metres (16.4 feet). Later estimates reduced this to about 3.5 metres (11.5 ft). Its skull was long, low, perfectly arched, and lacked a "keel" or any other crest sometimes seen in related species. The nasal opening and the large opening typically present between the nose and eye openings of archosaurs (the "antorbital fenestra") had joined together in species such as this to create a single oval opening that occupied nearly one half the length of the skull. The beak was long, thin, sharply pointed, and lacked teeth. The cervical vertebrae were elongated. The first six dorsal vertebrae had fused into a notarium. Several pairs of belly ribs were preserved. Its upper leg bone was half the size of its upper arm bone, and strong and thin. The wings were short but robust.

 Zhejiangopterus was by the original describers classified as a member of the Nyctosauridae, because of the two edentulous pterosaurs they possessed good descriptions of, Pteranodon and Nyctosaurus, it showed the most resemblance to the latter. They deplored lacking good data on Quetzalcoatlus. Indeed in 1997 David Unwin determined that Zhejiangopterus was more closely related to this giant American form and thus belonged to the Azhdarchidae. No other azhdarchid is known from such complete skeletal material.

 Volgadraco ("Volga River dragon") is a genus of azhdarchid pterodactyloid pterosaur from the Upper Cretaceous of European Russia. It is known from lower beak (holotype SGU, no. 46/104a) and postcranial fragments from the early Campanian-age Rybushka Formation of Saratov, Russia. The size of this animal, and the development of blood supply in the lower jaw, are intermediate between older Santonian or Turonian azhdarchids like Azhdarcho and Bakonydraco and later Maastrichtian azhdarchids like Quetzalcoatlus. Volgadraco was described in 2008 by Averianov, Arkhangelsky, and Pervushov. The type species is V. bogolubovi, the specific name honouring Russian paleontologist Nikolai Nikolaevich Bogolubov. The authors consider the earlier named genus Bogolubovia to be a nomen dubium that in fact might be identical to Volgadraco.

 Ученые из Саратовского государственного технического университета во время полевых работ в верхнемеловых отложениях южной части саратовского правобережья обнаружили кости летающих ящеров-птерозавров. 

"По мнению ведущего российского специалиста по птерозаврам профессора Александра Аверьянова (Зоологический институт РАН, Санкт-Петербург), кости относятся к представителям семейства аждархид. Это самые крупные летающие создания на нашей планете, обитавшие в конце мелового периода. 

 Как выяснилось, ранее останки Volgadraco bogolubovi «Волжский дракон Боголюбова» уже находили. Они являлись самыми крупными летающими созданиями на нашей планете, обитавшими в конце мелового периода. Их размах крыльев был более 10 метров и пропитание они добывали, пикируя на поверхностью водоемов, высматривая рыбу плавающую на небольшой глубине.

 Новые находки были сделаны доцентом кафедры "Геоэкология и инженерная геология" Саратовского технического университета Максимом Архангельским и участником исследовательской группы "Искатели" Сергеем Меркуловым. 

 "Вместе с останками птерозавров обнаружены и кости морских рептилий - плезиозавров, мозазавров и черепах. В ближайшее время экспедиционные работы по сбору ископаемых останков мезозойских рептилий будут продолжены", - цитирует сообщение РИА "Новости".
