Oldest T. rex relative identified

Scientists have identified the most ancient fossil relative of the dinosaur Tyrannosaurus rex.

The new addition to T. rex's clan is known from a 30cm-long skull uncovered during excavations in Gloucestershire in the 1900s.

The well-preserved fossil is held in London's Natural History Museum.

A British-German team has now uncovered evidence linking it to what may be the most famous dinosaur family of all.

The dinosaur, named Proceratosaurus, lived about 165m years ago, during the middle Jurassic Period.
