Shuvuuia deserti, a nocturnal dinosaur

Description

Context: Scientists on an examination of a ring of bones surrounding the pupil and a bony tube inside the skull that houses the hearing organ showed that this dinosaur, called Shuvuuia deserti, boasted visual and auditory capabilities akin to a barn owl, indicating it could it hunt in total darkness.

More about news:

Their study, showed that predatory dinosaurs overall generally possessed better-than-average hearing — helpful for hunters — but had vision optimized for daytime.
In contrast, Shuvuuia loved the nightlife.
Shuvuuia was a pheasant-sized, two-legged Cretaceous Period dinosaur weighing about as much as a small house cat.
Lacking the strong jaws and sharp teeth of many carnivorous dinosaurs, it had a remarkably bird-like and lightly built skull and many tiny teeth like grains of rice.
The fossilized skeleton of the small bird-like dinosaur Shuvuuia deserti is seen in this undated handout image.
Its mid-length neck and small head, coupled with very long legs, made it resemble an awkward chicken.
Unlike birds, it had short but powerful arms ending in a single large claw, good for digging.
Shuvuuia might have run across the desert floor under cover of night, using its incredible hearing and night vision to track small prey such as nocturnal mammals, lizards and insects.
