His son Will, on the other hand, has chosen to train as a messenger of the sky ; a Skybax rider, who lives in symbiosis with his mount, the great Quetzalcoatlus ( nicknamed Skybax ), a species of pterosaur.

Little is known about what it ate and how it lived, but a tooth of Saurornitholestes has been found embedded in the wing bone of a large pterosaur, probably a juvenile Quetzalcoatlus.

While some studies have historically found extremely low weight estimates for Quetzalcoatlus, as low as for a 10-meter individual, a majority of estimates published since the 2000s have been higher, and the tend toward.

There have been a number of different ideas proposed about the lifestyle of Quetzalcoatlus.

The later program featured traits invented by the producers to heighten entertainment value, including a depiction of Quetzalcoatlus with the ability to use ultraviolet vision to locate dinosaur urine when hunting in the air.

In the " Return to Jurassic Park " bonus feature of the 2011 Blu-ray release of the Jurassic Park film series, John R. Horner describes Quetzalcoatlus as the pterosaur that most accurately represented and matched the size of the pterosaurs that are featured in the films.

The dinosaurs featured were Edmontosaurus, Baryonyx, Styracosaurus, Troodon, Dilophosaurus ( returning and also having a juvenile ), Therizinosaurus, Allosaurus, Quetzalcoatlus ( not a dinosaur ), Sarcosuchus ( not a dinosaur ), Cryolophosaurus, Rugops, Kentrosaurus, Deltadromeus, Giganotosaurus, Brachiosaurus ( returning but in a new spot ), Carnotaurus, and Amargasaurus.

Skull material ( from the unnamed smaller species ) shows that Quetzalcoatlus had a very sharp and pointed beak, contrary to some earlier reconstructions that showed a blunter snout, based on the inadvertent inclusion of jaw material from another pterosaur species, possibly a tapejarid or a form related to Tupuxuara.

Because the area of the fossil site was four hundred kilometers removed from the coastline and there were no indications of large rivers or deep lakes nearby at the end of the Cretaceous, Lawson in 1975 rejected a fish-eating lifestyle, instead suggesting that Quetzalcoatlus scavenged like the Marabou Stork, but then on the carcasses of titanosaur sauropods such as Alamosaurus.

Though Quetzalcoatlus, like other pterosaurs, was a quadruped when on the ground, Quetzalcoatlus and other azhdarchids have fore and hind limb proportions more similar to modern running ungulate mammals than to their smaller cousins, implying that they were uniquely suited to a terrestrial lifestyle.

Pterosaurs spanned a wide range of adult sizes, from the very small Nemicolopterus to the largest known flying creatures of all time, including Quetzalcoatlus and Hatzegopteryx.

It may be of relevance that in 1985 the Smithsonian Institution commissioned aeronautical engineer Paul MacCready to build a half-scale working model of Quetzalcoatlus northropi.

Fossil trackways show that pterosaurs like Quetzalcoatlus northropi were quadrupeds.

Quetzalcoatlus () was a pterodactyloid pterosaur known from the Late Cretaceous of North America ( Maastrichtian stage, about 68 – 65. 5 million years ago ), and one of the largest known flying animals of all time.

When it was first discovered, scientists estimated that the largest Quetzalcoatlus fossils came from an individual with a wingspan as large as 15. 9 meters ( 52. 2 feet ), choosing the middle of three extrapolations from the proportions of other pterosaurs that gave an estimate of 11, 15. 5 and 21 meters respectively ( 36 feet, 50. 85 feet, 68. 9 feet ).

The first Quetzalcoatlus fossils were discovered in Texas, from the Maastrichtian Javelina Formation at Big Bend National Park ( dated to around 68 million years ago ) in 1971 by a geology graduate student from the University of Texas at Austin's Jackson School of Geosciences, Douglas A. Lawson.

That same year, in a subsequent letter to the same journal, he made the original large specimen, TMM 41450-3, the holotype of a new genus and species, Quetzalcoatlus northropi.

The specific name honors John Knudsen Northrop, the founder of Northrop, who was interested in large tailless flying wing aircraft designs resembling Quetzalcoatlus.

This possible second species from Texas was provisionally referred to as a Quetzalcoatlus sp.

sp., if not identical to Quetzalcoatlus northropi, represents a distinct genus.

An azhdarchid neck vertebra, discovered in 2002 from the Maastrichtian age Hell Creek Formation, may also belong to Quetzalcoatlus.

Quetzalcoatlus was abundant in Texas during the Lancian in a fauna dominated by Alamosaurus.

Quetzalcoatlus had precursors in North America and its apparent rise to widespreadness may represent the expansion of its preferred habitat rather than an immigration event, as some experts have suggested.

They suggested that with its long neck vertebrae and long toothless jaws Quetzalcoatlus fed like modern-day skimmers, catching fish during flight while cleaving the waves with its beak.

Besides I heard her old uncle that stays there has been doin' it ''.

Southern resentment has been over the method of its ending, the invasion, and Reconstruction ; ;

The situation of the South since 1865 has been unique in the western world.

The North should thank its stars that such has been the case ; ;

As it is, they consider that the North is now reaping the fruits of excess egalitarianism, that in spite of its high standard of living the `` American way '' has been proved inferior to the English and Scandinavian ways, although they disapprove of the socialistic features of the latter.

In what has aptly been called a `` constitutional revolution '', the basic nature of government was transformed from one essentially negative in nature ( the `` night-watchman state '' ) to one with affirmative duties to perform.

For lawyers, reflecting perhaps their parochial preferences, there has been a special fascination since then in the role played by the Supreme Court in that transformation -- the manner in which its decisions altered in `` the switch in time that saved nine '', President Roosevelt's ill-starred but in effect victorious `` Court-packing plan '', the imprimatur of judicial approval that was finally placed upon social legislation.

Labor relations have been transformed, income security has become a standardized feature of political platforms, and all the many facets of the American version of the welfare state have become part of the conventional wisdom.

Historically, however, the concept is one that has been of marked benefit to the people of the Western civilizational group.

In recent weeks, as a result of a sweeping defense policy reappraisal by the Kennedy Administration, basic United States strategy has been modified -- and large new sums allocated -- to meet the accidental-war danger and to reduce it as quickly as possible.

The malignancy of such a landscape has been beautifully described by the Australian Charles Bean.

There has probably always been a bridge of some sort at the southeastern corner of the city.

Even though in most cases the completion of the definitive editions of their writings is still years off, enough documentation has already been assembled to warrant drawing a new composite profile of the leadership which performed the heroic dual feats of winning American independence and founding a new nation.

Madison once remarked: `` My life has been so much a public one '', a comment which fits the careers of the other six.

Thus we are compelled to face the urbanization of the South -- an urbanization which, despite its dramatic and overwhelming effects upon the Southern culture, has been utterly ignored by the bulk of Southern writers.

But the South is, and has been for the past century, engaged in a wide-sweeping urbanization which, oddly enough, is not reflected in its literature.

An example of the changes which have crept over the Southern region may be seen in the Southern Negro's quest for a position in the white-dominated society, a problem that has been reflected in regional fiction especially since 1865.

In the meantime, while the South has been undergoing this phenomenal modernization that is so disappointing to the curious Yankee, Southern writers have certainly done little to reflect and promote their region's progress.

Faulkner culminates the Southern legend perhaps more masterfully than it has ever been, or could ever be, done.

The `` approximate '' is important, because even after the order of the work has been established by the chance method, the result is not inviolable.

But it has been during the last two centuries, during the scientific revolution, that our independence from the physical environment has made the most rapid strides.

In the life sciences, there has been an enormous increase in our understanding of disease, in the mechanisms of heredity, and in bio- and physiological chemistry.

Even in domains where detailed and predictive understanding is still lacking, but where some explanations are possible, as with lightning and weather and earthquakes, the appropriate kind of human action has been more adequately indicated.

The persistent horror of having a malformed child has, I believe, been reduced, not because we have gained any control over this misfortune, but precisely because we have learned that we have so little control over it.
