in Time of the Titans

Brachiosaurus (brack-ee-oh-saw-us; name meaning "Arm Lizard") is a genus of giant brachiosaurid sauropod dinosaur with long front arms that originated during the Late Jurassic and Early Cretaceous periods in what is now North America as well as Africa and Europe.

Named for the large bones of its foreleg, Brachiosaurus was an enormous sauropod, one of the largest dinosaurs ever discovered known from a complete skeleton. Brachiosaurus was a 13 meter tall, 23 meter long, 70 ton gargantuan reptile, that fed on the tops of Conifer trees in the Late Jurassic forests, sometimes felling them with their sheer bulk if they were taller than them or not.


Era & DiscoveryEdit

Brachiosaurus lived in North America, Africa, and Europe during the Late Jurassic Period to Early Cretaceous Period from 153–135 million years ago. It lived alongside other sauropods and other herbivores as well as predators like Allosaurus.

Brachiosaurus was first described by American paleontologist Elmer S. Riggs in 1903 and was arguably the largest living land animal of its day. Since then, they have become one of the most famous dinosaurs of all time.

Physical AttributesEdit


A Fully-Grown Adult Brachiosaurus

A gargantuan sauropod dinosaur that specialized in grazing on the treetops, thanks to an exclusive, monopolizing on the tops which "no other dinosaurs can reach", adult Brachiosaurus grew to a staggering 34–50 feet (10.5–15 m) tall (as tall as a three story building), measured 72–75 feet (22–23 m) long (the length of two buses), and weighed over 40–70 tons (80,000–140,000 lbs.; more than 10 adult elephants, give or take), making them the largest land animals that have ever existed in North America and one of the largest animals that ever walked Planet Earth.

Brachiosaurus is the archetypal giant Dinosaur of the Jurassic alongside the giant Diplodocidae genus Diplodocus. Brachiosaurus, thought once the largest Dinosaur ever known for decades, has some many years ago now been relegated - far surpassed by gigantic sauropod dinosaurs like Argentinosaurus. Nevertheless, Brachiosaurus is a mighty, majestic and awe-inspiring Dinosaur, as famous now as it has been for decades. Its name means, Arm Lizard, in reference to its and its whole families peculiar trait of having longer forelimbs - or 'arms' - than hindlimbs.

Named for the large bones of its forelegs, this dinosaur was an enormous sauropod. Brachiosaurus held its neck in a vertical position and was adapted to live on land, with similarities to a Giraffe, browsing in treetops. Its peg-like teeth were used to strip leaves from the high branches. Unlike many of its sauropod relatives, Brachiosaurus had very long forelegs, indicating that its neck was held in a more vertical position.

Behavior & TraitsEdit

Like all sauropods and other herbivorous dinosaurs, Brachiosaurus traveled in herds. When it came to juveniles, even adolescents, they often separated themselves from the herd. And if they were ever threatened by predators, such as Allosaurus, there was always an adult nearby to help. Their kind could effortlessly harvest cones and fresh leaves no other dinosaur could reach. And they had grown enormous on it. These giants were feeding almost constantly to sustain it enormous bulk.

They fed on the tops of Conifer trees in the Late Jurassic forests, sometimes felling them with their sheer bulk if they were taller than them or not. They fed on tall kinds of trees due to the teeth they had (chisel like) were not much sought after by anything else around; tough Conifer leaves and cones. Diplodocus for instance could only strip the soft ferns and cycads with their weak and simple peg like teeth.


Trivia Edit

  • Brachiosaurus is the second largest sauropod dinosaur, as well as the largest Jurassic dinosaur, brought to the park.
  • The sound effects of Brachiosaurus are that of modified elephant bellows as well as giraffe, moose, donkey, horse, and cow sounds.
