Dinosaurs: Brachiosaurus

 

Brachiosaurus (Arm Lizard)

Brachiosaurous was a large plant-eating Sauropod of the mid-to-late Jurassic. Until recently Brachiosaurus was believed to be the largest known dinosaur to ever have walked the earth reaching heights of up to 13 m (43ft) and weighing up to 75 tons (as much as 13 elephants).

Brachiosaurus, like most other Sauropods, had peg-like teeth, however unlike most of the other long-necked dinosaurs, Brachiosaurus could lower or lift its crane-like neck to browse on tree leaves or fern fronds, similar to that of a modern day giraffe. Like other Sauropods, Brachiosaurus teeth where perfect for stripping leaves but were not designed for chewing. Scientists believe that these creatures probably swallowed stones that they stored in their gizzard to mash their food.

Unlike most other Sauropods, and most other dinosaurs, Brachiosaurus front legs were longer than its hind legs. This is what earned it the name “arm lizard”. This peculiar feature gave it a back that sloped downwards towards its short tail and a long neck that pointed upwards.

Another unusual feature of Brachiosaurus was its nostrils which were located on the top of its head. This enabled the Sauropod to breathe whilst eating.

Brachiosaurus probably travelled in large herds with the larger adults protecting their young from hunting predators.
