BRONCOSAURUS REX PDF

This dossier section is intended to be an exact copy of what the survivor Helena , the author of the dossiers has written. There may be some discrepancies between this text and the in-game creatures. In fact, the dinosaur is so massive that it serenely ignores most other creatures. Domesticated Because of how docile it is, the Brontosaurus makes for an ideal pack animal. Peaceful tribes use it to carry incredible quantities of resources, while warring tribes use it to mobilize their army. Its size and strength make it one of the unique creatures on the Island that can support a "platform" saddle.

Despite the change in classification , the public still embraced the dinosaur as Brontosaurus, owing to the widespread use of its likeness during much of the 20th century in advertising, motion pictures , and television , as well as the presence of Brontosaurus reconstructions in museums throughout North America and Europe.

The genus Brontosaurus was reinstated in after a morphological study of the family to which those genera belonged revealed that the physical differences between Brontosaurus and Apatosaurus were enough to separate them into two genera.

BrontosaurusThe dinosaur Brontosaurus compared in size with a modern-day elephant. More than years after the genus Brontosaurus fell out of favour with taxonomists in , Swiss paleontologist Emanuel Tschopp and colleagues in April proposed restoring it as an official taxonomic unit. Shortly after he described it in the American Journal of Science, Brontosaurus became the iconic sauropod within scientific circles.

Marsh created a poster-sized paper reconstruction of the specimen in By that time Brontosaurus had gained fame as being the most-complete sauropod fossil ever discovered, and illustrations of the dinosaur also appeared in newspapers and other periodicals as the late 19th century drew to a close.

Museums made plans to place Brontosaurus reconstructions in their institutions, and in the American Museum of Natural History AMNH in New York City became the first to do so—the first dinosaur reconstruction of a sauropod dinosaur. Controversy erupted in , however, after a reevaluation of Apatosaurus and Brontosaurus specimens by American paleontologist Elmer Riggs.

Apatosaurus was first described in , two years before Brontosaurus, and, according to taxonomic naming rules, it therefore became the official genus under which both dinosaurs were classified. Consequently, the species B. Because no Brontosaurus skeleton had been found with its skull, his reconstructions of that animal featured a purely conjectural skull based partly on that of Camarasaurus.

That error coloured the perceptions of paleontologists, museum curators, and the public for decades. Not until did scientists find that Apatosaurus and, therefore, dinosaurs once identified as Brontosaurus had had a head much more like that of the sauropod Diplodocus.

After more-accurate measurements were taken, and the maximum head-to-tail length for Apatosaurus was estimated at 21— A study by Swiss paleontologist Emanuel Tschopp and colleagues estimated that an average-sized Brontosaurus weighed In contrast, the average Apatosaurus was heavier, weighing an estimated Get exclusive access to content from our First Edition with your subscription.

Museums were slow to adopt the change in classification, and several still labeled their specimens Brontosaurus until the s. The beloved Brontosaurus quickly surpassed Tyrannosaurus rex and Triceratops in popularity. American film producer Walt Disney highlighted it, along with other dinosaurs, in Fantasia , and a young animated Brontosaurus-like sauropod was the lead character in the film The Land Before Time Reinstating genus Brontosaurus Interest in restoring Brontosaurus as a valid genus has remained since Apatosaurus and Brontosaurus were merged into one.

Years before the publication of the paper by Tschopp and colleagues, some paleontologists argued that the differences between A. Beginning in the s, noted American paleontologist Robert Bakker argued that position, along with a subsequent name change; however, it was not until the paper by Tschopp and colleagues, that the reinstatement of Brontosaurus became a viable possibility. The paper focused on family Diplodocidae which contains Apatosaurus , and their endeavour was the largest phylogenetic analysis of sauropods performed up to that time.

Tschopp and colleagues examined individual physical features morphological characters spanning 81 different individual sauropods recovered from sites across the globe. They concluded that the differences between Apatosaurus and Brontosaurus were numerous enough to reinstate the latter as a valid genus. Natural history Brontosaurus closely resembled Apatosaurus both in anatomy and habit. Like Apatosaurus, Brontosaurus was quadrupedal, possessing four stout legs, as well as a long neck that was balanced by a long tail.

The first museum specimens measured at Brontosaurus was herbivorous and lived on land. Its long neck may have evolved to reach marshy vegetation some distance away or to reach leaves higher up in trees.

Brontosaurus also consumed stones to help grind up and digest unchewed plant matter once it reached the stomach.

Original electronic Scanned image These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background. For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book.
