While very little is known about pterosaur reproduction, it is believed that, similar to all dinosaurs, all pterosaurs reproduced by laying eggs, though such findings are very rare. The first known pterosaur eggs were found in the quarries of Liaoning, the same place that yielded feathered dinosaurs, and in Loma del Pterodaustro ( Lagarcito ...
Pterodactylus (from Ancient Greek: πτεροδάκτυλος, romanized: pterodáktylos ' winged finger ' [2]) is a genus of extinct 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.
However, both pterosaurs [39] and baurusuchids [40] have soft-shelled eggs, implying that hard shells are not a plesiomorphic condition. The pelvic anatomy of Cricosaurus and other metriorhynchids [ 41 ] and fossilized embryos belonging to the non-archosaur archosauromorph Dinocephalosaurus , [ 42 ] together suggest that the lack of viviparity ...
Tropeognathus is regarded as the largest pterosaur found in the Southern Hemisphere, only rivaled by the huge azhdarchids. [1] The type and only species is Tropeognathus mesembrinus . Fossil remains of Tropeognathus have been recovered from the Romualdo Formation , which is a Lagerstätte located in the Santana Group of the Araripe Basin in ...
Pteranodon (/ t ə ˈ r æ n ə d ɒ n /; from Ancient Greek: πτερόν, romanized: pteron ' wing ' and ἀνόδων, anodon ' toothless ') [2] [better source needed] is a genus of pterosaur that included some of the largest known flying reptiles, with P. longiceps having a wingspan of over 6 m (20 ft).
A new discovery of pterosaur eggs & fossils from the Hamipterus tianshanensis species in China gives us our most complete look at the early flying reptiles.
This makes the species one of the best known pterosaurs, with examples from all growth stages, from egg to adult. The genus was named in 1969 by José Bonaparte as an as yet undescribed nomen nudum. The first description followed in 1970, making the name valid, the type species being Pterodaustro guiñazui. [5]
Quetzalcoatlus (/ k ɛ t s əl k oʊ ˈ æ t l ə s /) is a genus of azhdarchid pterosaur that lived during the Maastrichtian age of the Late Cretaceous in North America. The type specimen, recovered in 1971 from the Javelina Formation of Texas, United States, consists of several wing fragments and was described as Quetzalcoatlus northropi in 1975 by Douglas Lawson.
