brachiosaurus dinosaur

Its name comes from the Greek: Brachion = arm and Sauros = lizard, the Brachiosaurus is a Sauropod and is known to have lived in Africa and North America about 145 million years ago in what was the end of the Jurassic period. You can recognize them if you look carefully since what makes them different from other Sauropods is that their front legs were longer than their back legs, hence the name Brachiosaurus, because of their long arms. It is said that they have certain similarities with modern giraffes, because of the characteristic of the extremities and also because both have a long neck. Its long neck was used to feed on the treetops and as a curiosity and rarity in this type of dinosaur, the first finger of its front and back legs had claws.

It has been estimated that it could weigh up to 60 tons and could reach 25 meters in length. Their teeth were spatula shaped, i.e. flatter and thinner when they reached the tip. He also had a very large nose with particularly open nostrils at the top of his head, which led many scientists to believe that he had an excellent sense of smell, even his huge nose led to the idea that he used it for diving and that the Brachiosaurus lived in the water, but this has not been proven and theories suggest that it would not have been able to withstand the pressure of the water if it had been submerged.

It is believed that Brachiosaurus, like other members of his family, had a small brain, especially considering the size of his body, but later studies have shown that the size of the brain was not related to intelligence, and even speculated that it might have structures that functioned as a second brain or aided the functions and intelligence of these dinosaurs.

In addition to everything because of their large size they did not have much to fear since their main predators, the Allosaurus were much smaller than them, and the Brachiosaurus moved in herds which made them even more difficult to hunt.

Elmer S. Riggs discovered the first Brachiosaurus in 1900, very early in the morning, taking into account that there are dinosaurs that were discovered in the last 50 years, these first remains of dinosaurs were found in Colorado, United States. Years later Werner Jenensch found a large number of bones in Tanzania, these were the first dinosaur remains found in Africa, these remains were taken to Germany and rebuilt with them to the first complete Brachiosaurus. These remains are considered the largest known dinosaur skeleton and above all the most complete, the most interesting thing that could be recovered and that differentiates it from any other dinosaur is that they recovered bones of the back, ribs, femur and vertebrae, so it was possible to estimate its size very accurately.

There are many theories about the way in which Brachiosaurus fed, they have not yet agreed whether the Brachiosaurus were hot-blooded or cold-blooded, if they had been hot-blooded, the amount of food they would need day by day to maintain their temperature and have energy to move, was to eat many kilos of food daily. The Brachiosaurus fed on high branches of the trees, it was a great advantage for them to eat foliage this way because they did not find many competitors, it is said that they were so big that they did not even need to lift their necks so much, but only by stretching them a little could they have access to foliage that many others could not reach. It is believed that they fed only on leaves and branches that were 5 meters above the ground and that they ate up to 400 kilograms of leaves a day.

What made Brachiosaurus special was its huge nose, that is, the huge openings in its skull through which it breathed and perceived all kinds of fine aromas. These openings are not in front as in most dinosaurs, but at the top of your head, at the top. At first it was assumed that because of their position in the body, their nose functioned as a respirator and that they therefore had to live mainly in the water, however, now that they know that the Brachiosaurus lived entirely on the land. Another much newer theory is that besides helping them to have a better sense of smell, it also helped them to hear much better because their nose worked as a kind of sounding board. As for the first theory, it was demonstrated that in addition to the water pressure, the shape of their extremities was narrow and that they could not function efficiently in the water, to swim and to move easily.

Where else can you find him?

The Brachiosaurus are well known dinosaurs, especially for the shape of their nose and for their large size, so they are usually portrayed in movies, toys and television programs, the most important of which are in Jurassic Park and its sequels and in the famous documentary Walking with Dinosaurs. In addition, an asteroid was named after him.
