Brontosaurus and Brachiosaurus are two genera of giant sauropods that lived in late Jurassic period to early Cretaceous . Brontosaurus is a sauropod that had forelimbs shorter than its hind legs while Brachiosaurus had longer forelimbs and shorter hind limbs. Apatosaurus, the correct name for what is also known as Brontosaurus, was approximately 20 feet shorter and 32 tons lighter than Brachiosaurus. Since taxonomy honors the name that came . Although the genus has subsumed Brontosaurus formally since 1903, a body of evidence suggests that Apatosaurus and . More than a century ago, the Brontosaurus was deemed too similar to the dinosaur Apatosaurus. . Short version: There has been debate over whether Brontosaurus is just a type of Apatosaurus or not. Key Differences Between Them Both. The largest species, B. excelsus, weighed up to 15 t (17 short tons) and measured up to 22 m (72 ft) long from head to tail. The study used 81 specimens from collections around the world and looked at 477 anatomical traits. . These two dinosaurs were closely related, but Apatosaurus was more heavily built, with stockier legs and . Although both are incredibly large dinosaurs in their own rights, the former is longer, while brachiosaurus was generally taller. Most of the differences were in tiny anatomical features, but one distinctive trait was that Apatosaurus has a wider neck than Brontosaurus. A potential difference between apatosaurus vs brontosaurus is their overall size. What is the difference between Diplodocus and Apatosaurus? Marsh in the 1880s, the dinosaur was identified in 1903 as a member of the Apatosaurus genus, which Marsh had found a few years earlier. However, in 2015, new studies seemed to find enough differences between the two and suggested Brontosaurus be reconsidered a valid genus. Apatosaurus was a herbivorous sauropod dinosaur that lived in North America during the Late Jurassic period. "The differences we found between Brontosaurus and Apatosaurus were at least as numerous as the ones between other closely related genera, and much more than what you normally find between species . Although the type species, B. excelsus, had long been considered a species of the closely related Apatosaurus, researchers proposed in 2015 that Brontosaurus is a genus separate from Apatosaurus and that it contains three species: B. excelsus, B. yahnahpin, and B. parvus.Brontosaurus had a long, thin neck and a small head adapted for a . One unusually big — but very incomplete — specimen from Oklahoma suggests Apatosaurus could grow even longer, maybe pushing 98 feet (30 meters) in total length.

"The differences we found between Brontosaurus and Apatosaurus were at least as numerous as the ones between other closely related genera, and much more than what you normally find between species," Dr. Robert Benson, an Oxford paleontologist who was part of team, said in a press statement. This bone is 6 feet 7 inches tall and weighs 2,800 pounds. It roamed the earth during the late Jurassic period, a time that there were estimated to be many sauropods and was so similar to the Apatosaurus that it was actually scrapped from being its own species for 100 years.A full explanation of this is further down. This bone is 6 feet 7 inches tall and weighs 2,800 pounds. Answer. . But most paleontologists do not accept this classification.

Brontosauruses weighed up to 33,000 pounds and reached a maximum of 28 feet in height. In such cases, scientific rules state that the oldest name — in this case Apatosaurus — takes precedent. In 1899 a team from the Field Museum in Chicago (USA) discovered another skeleton that seemed to be between the Apatosaurus and the Brontosaurus. Many of the anatomical differences between the two dinosaurs are obscure, Tschopp says, but Apatosaurus's stouter neck is an obvious one. Think like, horses and zebras. Brontosaurus, the 'Thunder Lizard', which since 1903 was thought to have been misclassified as Apatosaurus, is a distinct genus, Portuguese, Swiss and British palaeontologists announced after revealing 'conclusive evidence'.In other words, Brontosaurus is not only back, it had always been there.

Upon concluding their study, Tschopp's team suggested that, due to a number of physical differences, the original Apatosaurus and Brontosaurus could be classified as different genera, and so the Brontosaurus was resurrected. Currently, it's usually regarded as separate, but for most of the last century, it was thought to just be a type of Apatosaurus. At least, this is what scientists have believed since 1903, when . The look of Brontosaurus and the Brachiosaurus is the most significant distinction among the two.

The scientists conclude that three known species of Brontosaurus exist: Brontosaurus excelsus, the first discovered, as well as B. parvus and B. yahnahpin. The scientists ultimately showed that Brontosaurus was distinct from Apatosaurus, one of the main differences being that Apatosaurus was more massive and robust with a thicker and lower-set neck than Brontosaurus. The main difference between Brontosaurus and Brachiosaurus is that the Brontosaurus was a quadruped dinosaur with a loud, rumbling noise whereas the Brachiosaurus was a gigantic dinosaur with disproportionately long neck, small skull, and large overall size. Answer (1 of 2): Apatosaurus is bigger, it's neck is substantially stouter and with a rectangular shaped frame. In 1903, another paleontologist, Elmer Riggs, argued that the differences between Apatosaurus and Brontosaurus were not great enough to classify them as two distinct genera. However, as every armchair palaeontologist knows, Brontosaurus was in fact a misnomer, and it should be correctly referred to as Apatosaurus. It is estimated that apatosaurus often exceeded 25 tons in weight, while brontosaurus weighed closer to 15 tons. The double beamed chevron bones tapering from the centrum of the caudal vertebrae are unique to Diplodocus. Its fossil remains are found in North America and Europe. It reached over .
