Scientists have discovered a new relative of the Tyrannosaurus rex -- much smaller than the huge, ferocious dinosaur made famous in countless books and films, including Jurassic Park. The entire animal was only marginally longer than just the skull of a fully grown Tyrannosaurus rex, said researchers from the Virginia Tech College of Science in the US. The typical weight for a full-grown Tyrannosaurus rex is roughly nine tonnes. "Suskityrannus gives us a glimpse into the evolution of tyrannosaurs just before they take over the planet," said Sterling Nesbitt, an assistant professor at Virginia Tech College of Science. Suskityrannus has a much more slender skull and foot than its later and larger cousins, the Tyrannosaurus rex, researchers said.
