Diplodocus
The long-necked whip-tailed giant of the Late Jurassic/Dinosaurs & Extinct Animals
Diplodocus was one of the longest land animals ever to live, stretching up to 26 meters from nose to tail tip. Its remarkably long neck (6.5 meters) and even longer tail (up to 13 meters) gave it the proportions of a suspension bridge on legs. Despite its enormous length, Diplodocus was relatively lightweight for a sauropod, with a slender build and hollow vertebrae that reduced its mass. Its tail may have been capable of producing a sonic crack when whipped, making it a literal thunder lizard.
