The large nasal arch has been postulated as an adaptation for cooling the brain, as a surface for evaporative cooling of the blood. Like all of the other "long-necked" dinosaurs, the Brachiosaurus’ As with other In 1883, a sauropod skull was found near Garden Park, Colorado, at Felch Quarry 1, and was sent to Othniel Charles Marsh. Chief among them is a difference in the way the trunk vertebrae vary: they are fairly uniform in B. altithorax, but vary widely in the African material. However, even that may no longer be true, since the biggest known specimens The mounted skeleton of a B. brancai (or Giraffatitan) in the Humboldt This new History The genus Brachiosaurus, and type species B. altithorax, are based on a partial postcranial skeleton from Fruita, in the valley of the Colorado River of western Colorado. fossils.Brachiosaurus was a sauropod, one of a collection of four-legged, plant-eating dinosaurs with long necks and tails, and tiny brains.Unlike other families of sauropods, it had a giraffe-like build, with long forelimbs and a raised neck, which is certainly used to graze in the tops of trees. With the removal of the East African Giraffatitan, Brachiosaurus is known only from the Morrison Formation of western North America. dinosaur known.
It grew to over 85 feet in length, nearly 45 tonnes, and over 40 feet tall. in its skull to decrease weight. The humerus, or upper arm bone, of Brachiosaurus is over six feet long. sink into the mud. are now considered to be part of the new Giraffatitan genus. take ten years to reach full size. species, it is known from five incomplete skeletons, including at least Average Adult Weigth. Museum in Berlin is 4 stories tall, attainment 12 meters (39 feet) into Furthermore, other similar sized sauropods had no comparable structure. It probably fed mostly on foliage above 5 metres (16 ft). Brachiosaurus had teeth like chisels (spatulate), and nostrils on the top of its head, The best specimens of Brachiosaurus were from the species B. brancai, The first toe on its front foot, and It might have stood at If the Brachiosaurus was warm-blooded, it is predictable that it would animal. Like all sauropods, Brachiosaurus was homeothermic (maintaining a stable internal temperature) and endothermic (controlling body temperature through internal means), meaning that it was able to actively control its body temperature, producing the necessary heat through a high basic metabolic rate of its cells. giant Its diet likely consisted of ginkgos, conifers, tree ferns, and large cycads, with intake estimated at 200 to 400 kilograms (440 to 880 lb) of plant matter daily.
The Morrison Formation is interpreted as a semiarid environment with distinct wet and dry seasons, and flat floodplains. These inaccuracies resulted in overestimation of heat production and underestimation of heat loss. An important difference between the two genera is the overall body shape, with Brachiosaurus having a 23% longer dorsal (trunk) vertebrate series and a 20 to 25% longer and also taller tail. Giraffatitan brancai Janensch, 1914 (formerly B. brancai): The new type However, these calculations were based on incorrect assumptions about the available cooling surfaces (the large air sacs were not known), and a grossly inflated body mass.

It had short legs that had 5 toed feet and a short tail. withers over its shoulder and a rounded crest over its nostrils.
Among these were Brachiosaurus is thought to have been a high browser, feeding on foliage well above the ground. Brachiosaurus was an unusual dinosaur that lived 155.7 million to 150.8 million years ago during the mid- to late Jurassic Period. Several other sauropod genera were present in the Morrison Formation, with differing body proportions and feeding adaptations. which may indicate it, had a good sense of smell. the border of the forests and waved the head up and down, while it systematically A detailed study of all material, including the limb and girdle bones, by Michael Taylor in 2009 found that there are significant differences between Brachiosaurus altithorax and the Tendaguru material in all elements known from both species. Higher estimates are usually based on the Ultrasauros , which was originally measured to be an extremely large Brachiosaurus.
10 tons - 22,000 lbs.
Their length was around 26 metres (85 feet) They weighed about 40 tons (40,000kg). Brachiosaurus has three known species: It is thought to be a 'high feeder' like a giraffe - eating leaves on trees up to 9 metres high. Even if it did not hold its neck near vertical, and instead had a straighter neck, its head height may still have been over 9 metres (30 ft) above the ground. the first three on its hind feet had claws. which was found in the Tendaguru Beds of Tanzania, in Africa. Higher estimates are usually based on the This does not preclude the possibility that it also fed lower at times, between 3 to 5 metres (9.8 to 16 ft) up. the Brachiosaurus weighed anywhere from 28.3 to 58 metric tons (31.2 and 64 short tons) and may have been as long as 18-21 meters (59-69 feet). It used to be theorized that it used the nostrils on the top of its head time, it would not get any blood to the brain. Studies have shown that the water pressure would be too great 3.5 m - 11.4 feet.
Additionally, in proportion to the entire animal, the nasal arch is very small, and would thus have made only an insignificant contribution to heat loss. in the world, although the bones come from several different specimens. They may have traveled in Its bony frill and extra horns, as well as its size, distinguishes it from a rhinoceros, but its toothless beak did as well. The length was useful for reaching tall and leafy tree branches to graze on. 14 m - 50 feet. Brachiosaurus had a neck that could stretch up to about 30 feet.
