From Nature:
Ask any dinner-party palaeontologist and they’ll tell you that, despite its star turn in Jurassic Park, Tyrannosaurus rex didn’t live in the Jurassic period. But now a team in China has found a tyrannousaur that did, and it gives us valuable clues about the rise of this clan of prehistoric predators. The new species, found in Xinjiang province in northwestern China, lived around 160 million years ago. This makes it more than twice as old as T. rex, and the most primitive known member of the family.
At just 3 metres long, the creature is a small relative of T. rex, which could reach a mighty 13 metres. But its gaping, beak-like face armed with teeth, and its powerful legs, show that it too would have been a ferocious killer.
