Apatosaurus may be one of the best-known sauropod species, though it's just as likely you first heard about this late Jurassic giant under another name: Brontosaurus.. Why the two names? Apatosaurus was another giant sauropod that lived around the same time as Brachiosaurus between 155.7 to 150.8 million years ago, during the Jurassic Period. The generic name, coined by Othniel Charles Marsh in 1878, is a Neo-Latin term derived from Greek διπλόος (diploos) "double" and δοκός (dokos) "beam", in reference to its double-beamed chevron bones located in the underside of the tail. Brachiosaurus. As with other Brachiosauridae, it was over 40 feet tall. Brontosaurus, Apatosaurus and Diplodocus are very closely related species, all in the same family. Brachiosaurus () is a genus of sauropod dinosaur that lived in North America during the Late Jurassic, about 154-153 million years ago. It was a herbivore. There is a world somewhere between reality and fiction.

Diplodocus existed at the height of sauropod diversity, living alongside lots of other huge sauropods such as Barosaurus, Camarasaurus, Brachiosaurus, Apatosaurus, and Brontosaurus, which all would have specialized on different food sources and eating styles so as to reduce competition. (Credit: Davide Bonadonna, Milan, Italy) A new study, however, has revealed that Brontosaurus and Apatosaurus fossils have significant skeletal differences and are, in fact, two separate dinosaur genus. Furthermore, Brontosaurus is one of the longest dinosaurs while Brachiosaurus is one of the tallest dinosaurs that lived on Earth. One is an Apatosaurus and the other a Diplodocus.

Like most of the other sauropod species in Diplodocidae, it has a long, slender neck, stout, column-like limbs, and a long whip-like tail. The differences between Apatosaurus and Brontosaurus were so minor that the two were classified under the same genus. Othniel Charles Marsh described and named the first-known species, A. ajax, in 1877, and a second species, A. louisae, was discovered and named by William H. Holland in 1916.Apatosaurus lived about 152 to 151 . It was discovered within the Morrison formation alongside dinosaurs like Apatosaurus, Brachiosaurus, and Camarasaurus. This was done to make it easy for the audience to tell the difference between the Dilophosaurus and the Velociraptor. It had longer front limbs than hind limbs . It stood around 4.6 metres (15 ft.) tall at the shoulders. Dinosaurs are an extinct species of reptiles which dominated earth during the Jurassic period.

Both Apatosaurus and Brontosaurus are genera (basically one step above a species) describes in the late 19th century. Here, wild animals will be heard and respected. Very well put together guide Frank. Emanuel Tschopp, paleontologist at the University of Lisbon and lead author of the study, analyzed 81 dinosaur skeletons and 477 skeletal features from 18 museums in the United States . diplodocus was different from brontosaurus in a number of ways, diplodocus had a much longer tail and its neck was longer and more slender than brontosaurus.

Apatosaurus Size. Paleontologists estimate the Diplodocus could reach a maximum length of 80 . other species and genera of diplodocid dinosaurs, and were surprised by the result. In 1903, it was decided that the differences between Brontosaurus excelsus and Apatosaurus were so negligible that it was better to place them both in the same genus. Palaeontologists believe that Apatosaurus ('Brontosaurus') reached lengths of 70-75ft in length which is around 21-23 meters, so certainly not a small dinosaur. The scientists concluded that the sauropod family consists of the Apatosaurus, Diplodocus, and the Brontosaurus, and that there are three species of Brontosaurus. Also, the . Brontosaurus, which lived in North America around 150 million years ago in the Jurassic Period, was about 72 feet (22 meters) long and weighed about 40 tons. This forum is about the natural world.

Holland in 1916.They lived about 152 to 151 million years . The zygapophyseal shape in Diplodocus permitted less angular deflection laterally, but the longer neck resulted in similar total lateral deflection of about 4 m.

The name Apatosaurus ("deceptive lizard") wasn't inspired by the mixup between it and Brontosaurus; rather, Othniel C. Marsh was referring to the fact that this dinosaur's vertebrae resembled those of mosasaurs, the sleek, vicious marine reptiles that were the apex predators of the world's oceans during the later Cretaceous period. The initial goal of the research was to clarify the relationships among the species making up the family of sauropods known as the diplodocids, which includes Diplodocus, Apatosaurus and now . To date, the clade includes about 12 to 15 nominal species, some of them with questionable taxonomic status (e.g., 'Diplodocus' hayi or Dyslocosaurus polyonychius), and ranging in age from Late Jurassic to Early Cretaceous. In 1903, American paleontologist, Elmer Riggs, ascribed the differences between Brontosaurus and Apatosaurus and noticed that they're both the same genera of one animal with the former being considered invalid as Apatosaurus was named two years before (the rule in paleontology is that the animal that was named first has to be kept and remained . "The differences between Apatosaurus and Brontosaurus are numerous enough to revive Brontosaurus as a separate genus from Apatosaurus," Tschopp said.
