Tiny Hesperonychus elizabethae (far left), North America’s smallest meat-eating dinosaur, probably weighed no more than a chicken and was smaller than many of its contemporary relatives (human shown for scale).
There was a new dinosaur fossil discovered in 1982 in Canada at the Dinosaur Park, where over 30 species of dinosaurs have already been found. The new dinosaur was the size of a chicken and weighed about 4.2 pounds. This dinosaur broke the recored for being the smallest meat eating dinosaur in North America. The new dinosaurs scientific name is Hesperonychus Elizabethae.
This illustration shows Tianyulong confuciusi, an ornithischian dinosaur with featherlike structures. It lived in what is now northeastern China between 120 million and 130 million years ago.
This dinosaur died out more than 60 million years ago. Scientists are learning more and more about dinosaurs because of the fossils left behind. This tiny dino was found roaming around in southern Alberta, north of Montana. The claws on this Hesperonychus Elizabethae are sickle shaped, and its diet was insects, lizards, and birds. This dino is supposed to be related to the small raptor family
found in China.
About the same time Canada announced their discovery, the Chinese had announced that they also found dinosaur feathers. About 120-130 million years ago there were dinosaurs that had feathers, and were not a therapod they were a bird hipped dinosaur.
