Brontosaurus

Brontosaurus is a genus of sauropod dinosaur that lived in North America during the Late Jurassic period, about 154-150 million years ago. Its fossil was first discovered in Western North America in 1874 and first described in 1879 by American paleontologist, Othniel Charles Marsh at Yale University. The specimen still stands on display in the Great Hall of Yale’s Peabody Museum of Natural History. Brontosaurus was a large, long-necked, quadrupedal animal with a long, whip-like tail, and fore limbs that were slightly shorter than is hind limbs. Brontosaurus, like its close relative Apatosaurus, had tall spines on its vertebrae, which made up more than half the height of the individual bones. Its limb bones were also very robust. The arm bones are stout, with humerus resembling that of Apatosaurus. Brontosaurus is one of the best-known dinosaurs and has been featured in film, advertising and postage stamps, as well as many other types of media.

What You Need To Know About Brontosaurus

• Brontosaurus is a genus of sauropod dinosaur that lived in North America during the Late Jurassic period, about 154-150 million years ago.
• Its fossil was first discovered in Western North America in 1874 and first described in 1879 by American paleontologist, Othniel Charles Marsh at Yale University.
• Brontosaurus had a long, thin neck and a small head adapted for a herbivorous lifestyle, a bulky, heavy torso, and a long, whip-like tail.
• The forelimbs of brontosaurus were slightly shorter than its hind limbs.
• Adult individuals of Brontosaurus are estimated to have weighed up to 15 tonnes (17 short tons).  
• Brontosaurus is estimated to have been between 22 and 26 meters (72 and 76 ft) long.
• The skull of Brontosaurus has not been found, but was probably similar to the skull of the closely related Apatosaurus.
• Like those of other sauropods, the vertebrae of the neck were deeply bifurcated; that is, they carried paired spines, resulting in a wide and deep neck.

Brachiosaurus

Brachiosaurus is a genus of sauropod dinosaur that lived in North America during the Late Jurassic period, about 154-150 million years ago. Its fossil was first described by American paleontologist Elmer S. Riggs in 1903 from fossils found in the Colorado River Valley in Western Colorado, United States. Like all sauropod, Brachiosaurus was a quadruped with a small skull, a long neck, a large trunk with a high-ellipsoid cross-section, a long, muscular tail and slender, columnar limbs.

Branchiosaurus is among the most iconic and is regarded to be one among the largest dinosaurs. It is thought to have been a high browser, possibly cropping or nipping vegetation as high as 9 meters (30 ft) off the ground. Unlike other sauropods, it was unsuited for rearing on its hind-limbs. It has been used as an example of a dinosaur that was most likely ectothermic because of its large size and corresponding need for sufficient forage, but more research suggests it was warm-blooded.

• Brachiosaurus is estimated to have been between 18 and 21 meters (59 and 69 ft) long.
• It is estimated to have weighed between 28.3 to 58 metric tons.
• It had a disproportionately long neck, small skull and large overall size.
• Brachiosaurus had longer forelimbs than hind limbs, which resulted in a steeply inclined trunk, and a proportionately shorter tail.
