While most pterosaur skulls are composed of gracile plates and struts, in Hatzegopteryx the skull bones are stout and robust, with large ridges indicating strong muscular attachments. northropi. northropi". suggested that, in order to fly, the skull weight of Hatzegopteryx must have been reduced in some way. With a skull nearly 3 meters long and a 10 meter wingspan, it was as tall as a giraffe and the top predator on Hațeg Island.  A 38.5 cm (15.2 in) long middle section of a femur found nearby, FGGUB R1625, may also belong to Hatzegopteryx. Close. These were initially the basis of the taxon's referral to the clade Azhdarchidae, but they are also similar enough to be a basis for the synonymy of Hatzegopteryx and Quetzalcoatlus. The members of the Haţeg Island ecosystem lived on a landmass known as the Tisia–Dacia Block, of which the Haţeg Basin was a small part. , During the Maastrichtian, southern Europe was an archipelago. For most other giant azhdarchids, including Arambourgiania, this surface is less than 2.6 millimetres (0.10 in) thick.  Another pterosaur, Thalassodromeus, has similarly been suggested to be raptorial.  Along with the nodosaurid Struthiosaurus, various small, fragmentary maniraptorans were present: Bradycneme, Elopteryx, and Heptasteornis. Players also bu… Quetzalcoatlus / k ɛ t s əl k oʊ ˈ æ t l ə s / is a pterosaur known from the Late Cretaceous of North America (Maastrichtian stage) and one of the biggest known flying animals of all time. The study shows that one group of extinct animals where our dietary knowledge is lacking are the pterosaurs; extinct flying reptiles who lived in the Mesozoic Period 215–66 million years ago.

The latter is generally estimated at 10–11 metres (33–36 ft) in length. This unusual construction differs from that of other pterosaurs, and resembles more closely the structure of expanded polystyrene (used to manufacture Styrofoam). The largest of these remains indicate it was among the biggest pterosaur… , New specimens of Hatzegopteryx have since been recovered from other localities. Hatzegopteryx pictures depict this flying reptile as a somewhat unusual animal. While more evidence is still needed, all indicators seem to point to the fact that this flying reptile was probably a carnivore. There are a few things that make the Hatzegopteryx so unique: Even the hypothetically longer anterior neck vertebrae of Hatzegopteryx would be able to withstand four to seven body weights. The Hatzegopteryx fossil discovered on the Isle of Wight has shed new light on this magnificent species which some believe was the biggest flying creature of the period. It may have even fed on some of the small creatures which lived on the island at the time. The true tyrannical baron of the ark's skies, Hatzegopteryx is the undisputed king of flight. Hatzegopteryx ("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. The generic name is derived from the Hatzeg (or Hațeg) basin of Transylvania, where the bones were found, and from Greek pteryx (ἡ πτέρυξ, -υγος (also ἡ πτερύξ, -ῦγος), or 'wing'. Hatzegopteryx is a genus of azhdarchid pterosaur, known from incomplete remains found in Transylvania. Hatzegopteryx is a pterosaur whose fossils were found in Transylvania, Romania.  Pterosaurs had nine neck vertebrae; regression indicates that the third to seventh cervical vertebrae would have collectively measured 1.508 metres (4 ft 11.4 in) in length, with the longest vertebra - the fifth - only measuring approximately 400 mm (16 in) long. Due to lack of remains, the exact size of Hatzegopteryx is uncertain. It lived inland from the sea, near fresh-water ponds (so its diet was not primarily sea fishes and marine mollusks like other pterosaurs).
