Pterosaur sizePterosaurs included the largest flying animals ever to have lived. They are a clade of prehistoric archosaurian reptiles closely related to dinosaurs. Species among pterosaurs occupied several types of environments, which ranged from aquatic to forested. Below are the lists that comprise the smallest and the largest pterosaurs known . The smallest known pterosaur is Nemicolopterus with a wingspan of about . The specimen found may be a juvenile or a subadult, however, and adults may have been larger.
PterodaustroPterodaustro is a genus of ctenochasmatid pterodactyloid pterosaur from South America. Its fossil remains dated back to the Early Cretaceous period, about 105 million years ago. The first fossils, among them the holotype PVL 2571, a thigh bone, were discovered during the late 1960s by José Bonaparte in the Lagarcito Formation, situated in the San Luis Province of Argentina, and dating from the Albian. The genus has later also been found in Chile in the Santa Ana Formation.
PterodactylusPterodactylus (from Greek pterodáktylos (πτεροδάκτυλος) meaning 'winged finger') is an extinct genus of pterosaurs. It is thought to contain only a single species, Pterodactylus antiquus, which was the first pterosaur to be named and identified as a flying reptile and one of the first prehistoric reptiles to ever be discovered. Fossil remains of Pterodactylus have primarily been found in the Solnhofen limestone of Bavaria, Germany, which dates from the Late Jurassic period (Tithonian stage), about 150.8 to 148.
ArdeadactylusArdeadactylus (from Ardea – meaning "heron", and also a name of a genus of herons – and dactylus, meaning "finger") is an extinct genus of ctenochasmatoid pterosaur known from the Late Jurassic Solnhofen limestone of Bavaria, southern Germany. It contains a single species, Ardeadactylus longicollum, which was originally thought to be a species of Pterodactylus, as P. longicollum.
ThalassodromeusThalassodromeus is a genus of pterosaur that lived in what is now Brazil during the Early Cretaceous period, about a hundred million years ago. The original skull, discovered in 1983 in the Araripe Basin of northeastern Brazil, was collected in several pieces. In 2002, the skull was made the holotype specimen of Thalassodromeus sethi by palaeontologists Alexander Kellner and Diogenes de Almeida Campos. The generic name means "sea runner" (in reference to its supposed mode of feeding), and the specific name refers to the Egyptian god Seth due to its crest being supposedly reminiscent of Seth's crown.
DorygnathusDorygnathus ("spear jaw") was a genus of rhamphorhynchid pterosaur that lived in Europe during the Early Jurassic period, when shallow seas flooded much of the continent. It had a short () wingspan, and a relatively small triangular sternum, which is where its flight muscles attached. Its skull was long and its eye sockets were the largest opening therein. Large curved fangs that "intermeshed" when the jaws closed featured prominently at the front of the snout while smaller, straighter teeth lined the back.
ArambourgianiaArambourgiania is an extinct genus of azhdarchid pterosaur from the Late Cretaceous period (Maastrichtian stage) of Jordan, and possibly the United States. Arambourgiania was among the largest members of its family, the Azhdarchidae, and it is also one of the largest flying animals ever known. The incomplete left ulna of the "Sidi Chennane azhdarchid" from Morocco may have also belonged to Arambourgiania. In the early 1940s, a railway worker during repairs on the Amman-Damascus railroad near Russeifa found a two foot long fossil bone.
HatzegopteryxHatzegopteryx ("Hațeg basin wing") is a genus of azhdarchid pterosaur found in the late Maastrichtian deposits of the Densuş Ciula Formation, an outcropping in Transylvania, Romania. It is known only from the type species, Hatzegopteryx thambema, named by Buffetaut et al. in 2002 based on parts of the skull and humerus. Additional specimens, including a neck vertebra, were later placed in the genus, representing a range of sizes. The largest of these remains indicate it was among the biggest pterosaurs, with an estimated wingspan of .
ZhejiangopterusZhejiangopterus 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 Latinized 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 in Linhai.
AraripesaurusAraripesaurus is a genus a pterosaur belonging to the suborder Pterodactyloidea, it was discovered in the Romualdo Formation of the Santana Group in northeastern Brazil, which dates back to the Aptian and Albian of the Early Cretaceous. The type species is A. castilhoi. The genus was named in 1971 by Brazilian paleontologist Llewellyn Ivor Price. The type species is Araripesaurus castilhoi. The genus name refers to the Araripe Plateau. The specific name honors the collector Moacir Marques de Castilho, who in 1966 donated the chalk nodule containing the fossil.
