There are many modern-day nocturnal predators, animals that hunt at night under cover of darkness, including barn owls, bats, leopards and hyenas. But what about 100 million years ago, during the time of the dinosaurs? Were there any nocturnal beasts roaming around in the dark way back then? New research suggests there were.
Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. Scientists at the University of the Witwatersrand, Johannesburg have announced a new fossil analysis with evidence that two different species of theropods – three-toed, bidepal carnivorous dinosaurs – displayed these kinds of advanced nocturnal abilities. ....

This nocturnal dinosaur had owl-like night senses | Earth

New research shows that a small dinosaur called Shuvuuia deserti, that lived in the deserts of what's now Mongolia, had exceptional night vision and hearing, similar to modern day owls and other night predators. ....

Today, barn owls, bats, leopards and many other animals rely on their keen senses to live and hunt under the dim light of stars. These nighttime specialists avoid the competition of daylight hours, hunting their prey under the cloak of darkness, often using a combination of night vision and acute hearing.
But was there nightlife 100 million years ago? In a world without owls or leopards, were dinosaurs working the night shift? If so, what senses did they use to find food and avoid predators in the darkness? To better understand the senses of the dinosaur ancestors of birds, our team of paleontologists and palaeobiologists scoured research papers and museum collections looking for fossils that preserved delicate eye and ear ....

This Tiny Dinosaur Hunted At Night And Could Hear Better Than An Owl

Shuvuuia s hearing ability was as good as an owl’s
It roamed in the present-day Gobi Desert region in Mongolia
A new study has revealed that a tiny, carnivorous dinosaur, which had an exceptional low-light vision and whose hearing ability was as good as an owl s, hunted its prey at night. Measuring only 2 feet, the three-toed dinosaur species named Shuvuuia had large eyes and longer cochlea the part of the inner ear canal that holds sensory receptors. The creature used these abilities to see in the dark and hear even better than the barn owl. This particular species roamed the Earth about 75 million to 81 million years ago (late Cretaceous period) in the present-day Gobi Desert region in Mongolia. ....

An artistic reconstruction of two night-hunting Shuvuuia deserti emphasizes the dinosaur s resemblance to an owl.
A tiny, meat-eating dinosaur had superb low-light vision and hearing that was likely as good as an owl s. And like an owl, the wee dinosaur probably used those exceptional abilities to stalk and catch its desert prey under the cover of darkness.
Owl-like
Shuvuuia (shu-VU-ya) was a theropod a three-toed and bipedal carnivorous dinosaur. There s only one known species,
Shuvuuia deserti, and it was smaller than a domestic cat, measuring just 2 feet (0.6 meters) long. ....
