High School Student Finds Smallest, Youngest, Most Complete Duck-Billed Dinosaur Fossils Ever

In Utah

A dinosaur skeleton discovered by an eagle-eyed high-school student turns out to be the smallest, youngest and most complete duck-billed dinosaur of its kind ever found.

This Cretaceous-era herbivore, Parasaurolophus, walked the Earth some 75 million years ago. The dinosaurs in this genus are best known for their impressive tube-shaped head crests, which may have been used for display or perhaps to amplify the animals' calls. The little specimen, dubbed "Joe," was so young that its crest was a mere bump on its head.
