Researchers find new dinosaur in Uzbekistan

Researchers said Monday they have discovered the fossilized remains of a new horse-sized dinosaur that revealed how Tyrannosaurus rex (T. rex) became one of Earth’s top predators about 70 to 80 million years ago.

Lead researcher Stephen Brusatte from the University of Edinburgh said: ‘It’s one of the very closest cousins of T-Rex, but a lot smaller – about the size of a horse.

‘And it comes from the middle part of the Cretaceous period – a point where we have a huge gap in the fossil record.’

The newly-discovered dinosaur – dubbed Timurlengia euotica – lived around 90 million years ago, south of what is now the Aral Sea.

It suggests that tyrannosaurs evolved relatively quickly, becoming the monstrous killing machine T-rex within 10 million years.

Timurlengia euotica’s inner ears already had tyrannosaur features associated with agility and hearing low-pitched sounds, which might have helped it detect prey at a distance.

But it lacked the massive bone-snapping teeth and large sinuses of its later relation.

The fossils found include a braincase and bones from the neck, back, tail, feet and hands.
