Not until 1978 did scientists find that Apatosaurus (and, therefore, dinosaurs once identified as Brontosaurus) had had a head much more like that of the sauropod Diplodocus. The Apatosaurus was first named in 1877 by a Yale University paleontology professor, Othniel Charles Marsh. In 1877 Marsh named Apatosaurus ajax, a long-necked and long-tailed dinosaur found in the Morrison Formation in Colorado, USA. Riggs was an American palaeontologist who specialised in fossil mammals, but also named another well-known sauropod dinosaur, Brachiosaurus. The study used 81 specimens from collections around the world and looked at 477 anatomical traits. This dinosaur is best known for its large neck, which serves as sort of a counter balance for its long tail. Image by Charles Knight via Wikimedia commons (CC0 1.0). This research, published in 2015, was only possible because a number of new diplodocid dinosaurs had been found in recent decades. Diplodocus belongs to the same family as Brontosaurus and Apatosaurus, but was a more slender animal. Brontosaurus and Apatosaurus were discovered at a time in the late 1800s known as the Bone Wars or the Great Dinosaur Rush. Find out what Museum scientists are revealing about how dinosaurs looked, lived and behaved. They had small heads supported by an extremely long neck, with a tail which was often even longer. Unlike other Diplodocids, the Apatosaurus was far heavier, a mass of many tonnes which would be equivalent to 4 or 5 elephants. Living elephants are similar in that they live on land but spend time near water to bathe and drink, and can cross large rivers to reach new feeding grounds. Brontosaurus was believed to be an Apatosaurus mistakenly classified as a new species.) The claws were probably for defense, feeding, or grasping. Specifically pertaining to the Brontosaurus baxterii species native to the 2005 King Kong film, after living on Skull Island for millions of years, their ancestral Brontosaurus population on Skull Island had evolved to give live birth, usually in litters of two to three. The name Brontosaurus means ‘thunder lizard’, however, its primary name is actually Apatosaurus, ‘deceptive lizard’. As for food, it is worth noting how in principle it was thought that the diets of these animals were really poor, but after several investigations carried out by German paleontologists his could know, emulating the intestines of large dinosaurs, that perennial trees and the ferns served to set up a really nutritious diet. Thanks to this, it was possible to know that it was possible that sauropods and other reptiles had grown so much to reach huge sizes based on their diet on these foods. These animals in some cases exceeded 40 meters long and 100 tons. When archeologists found a skeleton near some Brachiosaurus skull pieces, paleontologists used the bones to speculate the shape of the head. Get email updates about our news, science, exhibitions, events, products, services and fundraising activities. Shortly after Cope and Marsh’s deaths, a paleontologist studying Marsh’s work noticed that the Apatosaurus and Brontosaurus skeletons were really similar – so similar that the scientific community deemed the Brontosaurus excelsus an adult specimen of the Apatosaurus genus. There are sev… These traits suggest that the neck could have been optimised to resist damage from impacts such as those caused by smashing the neck downwards or sideways onto something. Apatosaurus, genus of at least two species of giant herbivorous sauropod dinosaurs that lived between about 156 million and 151 million years ago. By this time, the Morrison Formation had becom… Or perhaps they were able to sweep their long necks over a large area of lower vegetation to feed efficiently without having to move too much. They reasoned that the dinosaurs' bodies were so massive that they wouldn't have been able to support their own body weight if they lived on land, and instead would have used the water to help hold them up. They could grow to over 80 feet long and weigh approximately 35 tons. Due to this dinosaur’s size, muscle movement, and recoil after each stride, it moved slowly and probably covered between 12 and 25 miles in a single day with an average 12-19 miles per hour speed. Image via Wikimedia Commons (CC0 1.0). Millions of years ago, during the time in which they inhabited the Brontosaurus there was a multitude of conifers, ferns and other plants of similar characteristics since the current flowers had not yet expanded throughout the world so that the Brontosaurus diet It was based mainly on this type of vegetables.

At one time it was speculated that Brontosaurus Dinosaur lived in waterlogged areas, because their nostrils were on the top of its head, so the nostrils help them to breathe in deep water. The Apatosaurus was part of the Diplodocid’s, the ‘Double beams’, named after the twin extensions in the bones of their tails. It started around 163.5 million years ago, and ended around 145 million years ago. We are open! Another mistake linked to this dinosaur was in relation to the creature’s head, which was believed to be like that of the Camarasaurus, whose head was box-like, though soon enough the real head of the Apatosaurus was found and it was more like horse’s head, being long and low. The Brontosaurus is a dinosaur that had a long, large neck, a large body, short limbs, and a tail that was similar in shape to a whip. The long-necked, long-tailed, 30-ton Brontosaurus is one of the most famous dinosaurs of all time. The Brontosaurus was related to other diplodocids like the Barosaurus, the Supersaurus and the Diplodocus. An enormous, viviparous apatosaurine diplodocid from Skull Island. Some experts have been more hesitant, however. They were four-legged creatures of immense size, reaching 27m in length, which can be compared to the length of a tennis court. Brontosaurus was one of the biggest plant eating sauropods of skull island. The Apatosaurus (Brontosaurus) is believed to have lived within Western North America, its fossils having been found in Colorado, Wyoming, Utah and Oklahoma. This dinosaur is best known for its large neck, which serves as sort of a counter balance for its long tail. Brontosaurus is a herbivore dinosaur that lived around one hundred fifty million years ago—during the Jurassic period—in the Western part of the Northern Hemisphere. There are three recongized specices of Brontoasaruses and they are B. excelsus (type species), … This was done to give calves, who could walk within h… Too bad it was missing a head.. This was because its nostrils are on the top of its head. The largest animals on Skull Island, the mighty Brontosaurus are capable of reaching lengths of 80-120 feet. Book your free ticket in advance. Shortly after Marsh's death and the discovery of a dinosaur skeleton with features of both Apatosaurus and Brontosaurus, Elmer Riggs argued in a 1903 publication that there were not enough similarities between the two dinosaurs for both genera to exist. Brontosaurus lived during the Late Jurassic epoch. Prof Paul Barrett, a dinosaur researcher at the Museum, says, 'The skeletons of Apatosaurus and Brontosaurus are very similar to each other in many ways, and other than their general proportions are mainly distinguished by detailed differences in the neck and back, and shoulder bones. Historically, scientists thought that large dinosaurs like Brontosaurus would have spent most of their time in water. Diplodocids were part of a branch of the larger family of Sauropods, ‘Lizard Feet’. The Brontosaurus technically hasn't existed in the living/breathing sense of the word for 150 million years. Brontosaurus is an invalid name for Apatosaurus excelsus, which lived in North America. After 1978 more-accurate measurements were taken, and the maximum head-to-tail length for Apatosaurus was estimated at 21–22.8 metres (68.9–74.8 feet). But did it ever exist? Although the mistake was spotted by scientists by 1903, the Brontosaurus lived on, in movies, books and children's imaginations. Their dwelling place was mostly around flood plains and their teeth were peg-shaped existing only at the front of the jaw, suited to there diet which consisted of plants. It is believed that the Brontosaurus are animals that lived between 154 and 150 million years, specifically during the upper Jurassic and in the area that is now known as North America, more specifically in the Morrison Formation. Marsh named it Brontosaurus excelsus, meaning 'noble thunder lizard'. The Brontosaurus is a well-known dinosaur today. Apatosaurus ajax was named in 1877, and Brontosaurus excelsus in 1879, both by Othniel Marsh. Brontosaurus was a large sauropod, a group of typically large dinosaurs with long necks and long tails. Brontosaurs is known for its very long neck useful for eating foilage off trees and shrubs. The oldest brontosaurus specimens are thought to be around 155 million years old. Getting a Head. Where did Brontosaurus Live? It is believed that his metabolism was very similar to that of current elephants. Therefore, a dinosaur of, for example, 76 tons, had to ingest the amount that an elephant of 10 tons can consume, multiplied by four. For other animals today this could be a problem, but not for the brontosaurus, which did not chew their food and that is why they could eat huge amounts of food and vegetables a day without this representing any problem for them. When Did Brontosaurus Live? Originally named by its discoverer Othniel Charles Marsh in 1879, Brontosaurus had long been considered a junior synonym of Apatosaurus; its original species Brontosaurus excelsus was reclassified as A. excelsus in 1903. The film’s fictional Brontosaurus baxteri is said to be capable of live birth. In fact, Brontosaurus does not exist! Brontosaurus is not aggressive, but can deal damage to players or dinosaurs by stepping on them if provoked. It was originally a different genus from Apatosaurus, but the type species Brontosaurus excelsus was reclassified as a species of Apatosaurus called Apatosaurus excelsus, meaning Brontosaurus was considered scientifically invalid for over 110 years. However, an extensive study published in 2015 by … About Brontosaurus. It could be that, like giraffes, sauropods including Brontosaurus used its long neck to get to leaves out of reach of other herbivores looking for food. When and where did the Brontosaurus live? It lived during the Late Jurassic Period, from about 156 to 145 million years ago. That was until a study in 2015 unexpectedly found evidence that Brontosaurus was distinct from Apatosaurus all along, signalling the reinstated status of this iconic dinosaur. Some cite that there are just as many differences between Apatosaurus and Brontosaurus as there are between other closely related genera, and many more differences than there often is between species of the same genus. Apatosaurus louisae is known from one nearly complete skeleton, which was found in Utah.In 2008, footprints of a juvenile Apatosaurus were found in Quarry Fi… These dinosaurs have thicker necks than many other sauropods, and they are more triangular in cross section. So in 1903, Brontosaurus lost its official status. The shape may have protected important soft tissue such as the trachea (windpipe) and major blood vessels. His legs weighed more than two hundred kilos each of them since he needed very strong limbs that could support the entire weight of his body. His neck and tail served as a counterweight and the latter, in the form of a whip, also helped him defend himself against his enemies. Although they were not very intelligent, they managed to survive for a long time due to their large size.
