How Brachiosaurus Got Its Name?

In 1903, he named the type species Brachiosaurus altithorax. Riggs derived the genus name from the Greek brachion/βραχίων meaning "arm" and sauros/σαυρος meaning "lizard", because he realized that the length of the arms was unusual for a sauropod.

How did the Brachiosaurus get its name?

Its long neck made it look like a giraffe, and its forelegs were longer than its hind legs. The name Brachiosaurus, in fact, means "arm lizard." Brachiosaurus was likely a warm-blooded animal.

What does Brachiosaurus stand for?

The name Brachiosaurus means “arm lizard” and refers to the animal's odd backward construction relative to other sauropods. Most sauropods' back legs grew longer than their arms, but Brachiosaurus turns that pattern around. As a result, the spinal column tilts upward, angling the neck higher than other sauropods.
