You are a Diplodocus!

Diplodocus

Diplodocus means "double beam", a name used to describe the two rows of bones discovered on the underside of the Diplodocus' lengthy tail. At around 100 feet long, this dinosaur was one of the longest to roam the Earth, but, as a herbivore, its impressive whip-cracking tail was just for self-defense.

Like the Diplodocus, you're a bit of a gentle giant and your bark is much worse than your bite. Speed is not your thing, and you don't see the point in rushing around; you'd much rather take your time and enjoy the view!
