A dino-bird hunted in total darkness 65 million years ago

A tiny dinosaur bird that inhabited the area of the Mongolian desert more than 65 million years ago possessed the incredible ability to see in the dark, Meilonline reported, citing results from a study by paleontologists.
The bizarre dino-bird the size of a small hen had proportionally the largest pupils among dinosaurs and even among modern birds, experts said.

The dino-bird, called shuvuya, was a theropod, a species of dinosaurs characterized by hollow bones and limbs with three fingers each. They also belong to Tyrannosaurus rex, BTA reported.

Shuvuya was discovered more than twenty years ago. This little desert dinosaur fed mainly on termites as well as plants. His lower jaw was not attached to the skull and this allowed shuvuya to open his mouth wide to swallow more prey. Shuvuya had a bird's skull, long legs and muscular limbs.

"Activity at night, ability to dig and long limbs today possess all animals inhabiting the desert. But it is surprising to see them presented in a dinosaur that lived more than 65 million years ago,” said the study leader Prof. Jonah Shoaniere of the University of Witwatersrand in Johannesburg, South Africa.

Scientists used computed tomography and accurate measurement methods to gather information about the relative dimensions of the eyes and inner ear of nearly 100 species of living birds and extinct dinosaur species, including the dino-bird.

The study has found that the extremely large bearing of shuvuya is almost identical to this structure in the inner ear of the modern veiled owl. This leads scientists to think that the dino-bird could hunt in complete darkness.

The veiled owl, which can hunt in complete darkness, relying mainly on its hearing, has the largest camp among modern birds.
