I WONDER - Was The Brachiosaurus A Sauropod?

The video discusses the characteristics of sauropods, a group of dinosaurs known for their long tails, necks, small heads, and four pillar-like legs. It highlights the Brachiosaurus, which differs from other sauropods due to its longer front legs, preventing it from rearing up on its hind legs. This unique feature led to its name, meaning 'armed reptile.' Additionally, the Brachiosaurus had a shorter tail compared to other sauropods.

Why is the Brachiosaurus referred to as the 'armed reptile'?

In what way does the tail of the Brachiosaurus compare to other sauropods?
