World's Smallest Dinosaur

A new fossil discovery could be the world's smallest known dinosaur — a feathered, birdlike creature that lived more than 100 million years ago and grew no more than 15.7 inches (40 centimeters) long.

The fossil, a tiny neck bone found in the southern U.K., is a mere quarter-inch (7.1 millimeters) in length. It belongs to an adult dinosaur that lived in the Cretaceous period 145 million to 100 million years ago, reported University of Portsmouth paleozoologist Darren Naish in the August issue of the journal Cretaceous Research.

That would put the animal in the running for world's tiniest dino, a title currently held by Anchiornis, another birdlike dinosaur that lived in what is now China 160 million to 155 million years ago.
