Brachiosaurus

Brachiosaurus was a massive, long-necked dinosaur that lived during the Jurassic period, around 154 to 150 million years ago. It is distinguished by its unusually long front legs, which gave it a giraffe-like appearance, allowing it to reach high vegetation. This herbivorous dinosaur could grow up to 85 feet long and weigh as much as 56 tons. Unlike many other sauropods, its nostrils were located on the top of its head. Brachiosaurus was a gentle giant, roaming in herds and primarily feeding on leaves and plants found in the treetops of its lush, prehistoric environment.
