Brachiosaurus (Pronunciation: BRAK-ee-oh-SAW-rus) was one of the world’s largest and tallest animals ever to exist. It had a long neck, small head, and relatively short, thick tail. An adult dinosaur could measure up to 25 meters in length, 13 metres in height and weighting up to an estimated 80 tonnes.
The first incomplete skeleton find was in the 1900 at the Grand Junction, Colorado, United States. It was only a couple of years later that several fine skeletons were found in Tendaguru, Tanzania.
They were to exist in the late Jurassic period 150 to 145 million years ago. It takes its name “arm reptiles” from its’ abnormal length of its forelegs when compared to its high limbs, causing its back sloped upwards towards the head.
Brachiosaurus has jaws that were reasonably short with chisel-like teeth for nipping leaves and fruit from tall conifer trees and nostrils on top of its head with large openings signifying that it may have had a good sense of smell. They had 26 teeth on its top jaw and 26 on the bottom for a total of 52 teeth towards the front of the mouth. Due to their upright stance and elevated neck, this meant that it could graze from trees at heights not other sauropod could reach.
