Brachiosaurus, which means "long-armed lizard", is one of the tallest and largest dinosaurs. It is the tallest dinosaur known to have a complete skeleton.

Brachiosaurus had a long neck, a small head and a stubby tail. Walk on all fours. Brachiosaurus' front legs were longer than its rear legs. Each foot has five toes. There are claws on one toe of each forefoot and three toes on each hind paw. Brachiosaurus' teeth were straight and sharp. Brachiosaurus's nostrils grew on the top of his head. Brachiosaurus had a small head, so it was not very clever. They live in groups and go out together. Brachiosaurus didn't make nests when it gave birth to young dinosaurs, but gave birth while walking, so these dinosaur eggs formed a long line. Brachiosaurus didn't look after his children. When they eat, Brachiosaurus swallows the whole food without chewing.

Brachiosaurus is one of the largest and heaviest dinosaurs ever. A man's head can only reach the knee of this monster. It has a huge body, a long neck, a small head and a long tail. A huge and strong heart kept pumping blood from the neck of Brachiosaurus to its cerebellum. Some scientists think it may have several hearts that send blood to all parts of its huge body. Along the cervical spine, well-developed muscles help support its head. Unlike other dinosaurs, brachiosaurus had longer front legs than its rear legs, which helped it support the weight of its long neck. Brachiosaurus ate the young leaves on the treetops, which other herbivores could not reach. With its long neck, it can pick the tallest leaves. So do giraffes today. Brachiosaurus had a well-developed jaw, like a sharp-edged spoon-shaped tooth, which could pinch off twigs and tree buds. Brachiosaurus needs to eat a lot of food to supplement the energy needed for its huge body to grow and move around. An elephant can eat about 1500 kg of food a day, and brachiosaurus can eat about1500 kg a day, which is ten times the food intake of today's behemoths! It may wander in groups on the endless prairie every day, looking for fresh trees.

Brachiosaurus is one of the large dinosaurs, which lived in Jurassic period. You can easily see the difference between it and other dinosaurs from the fact that its forelimbs are longer than its hind legs. Its shoulders are about 5.8 meters off the ground, and its head is about 12 meters off the ground when it is lifted. Although it may feed on branches and leaves of tall trees, some scientists don't think it will keep its head up for a long time-that will make it difficult for it to send blood up. Brachiosaurus was the largest land animal in history. Although dinosaurs such as super dragon, dragon and earthquake dragon have been dug up, it is still uncertain because no complete skeleton has been dug up. Brachiosaurus, Lei Long and Liang Long all had nostrils on their heads. It is easy for such a tall animal to feed on the branches and leaves of big trees. Like other giant herbivorous dinosaurs, it has a long neck and a small head, and the mound above it is its nose. Brachiosaurus had high forelimbs, hunched shoulders, and the whole body leaned back along the shoulders, which can still be seen in some tall animals such as giraffes.
