76 million-year-old dinosaur skeleton to be auctioned in New York City

The fossilized skeleton of a T. rex relative that roamed the earth about 76 million years ago will be auctioned in New York this month, Sotheby's announced Tuesday.

The Gorgosaurus skeleton will highlight Sotheby's natural history auction on July 28, the auction house said.

The Gorgosaurus was an apex carnivore that lived in what is now the western United States and Canada during the late Cretaceous Period. It predated its relative the Tyrannosaurus rex by 10 million years.
