The largest of non-pterodactyloid pterosaurs as well as the largest Jurassic pterosaur [16] was Dearc, with an estimated wingspan between 2.2 m (7 ft 3 in) and 3.8 m (12 ft). [17] Only a fragmentary rhamphorhynchid specimen from Germany could be larger (184 % the size of the biggest Rhamphorhynchus ). [ 18 ]

Inabtanin alarabia is one of the most complete pterosaur fossils ever found from this region, according to the researchers. The reptile was smaller than Arambourgiania with a wingspan of 16.4 feet ...
In addition to indeterminate remains, several species have been identified from both the rhamphorhynchoids (long-tailed pterosaurs) and pterodactyloids (short-tailed pterosaurs). [47] Since the 1970s and 80s, pterosaur finds have become more common, but are still rare. [47] Most Morrison pterosaurs have been found in marine and shoreline ...
A crocodile-like creature bit the neck of a flying dinosaur some 76 million years ago – and scientists have proof.. Archaeologists found the fossilized neck bone of the young pterosaur in Canada ...
