Small Owl-Like Dinosaur Had Extraordinary Night Vision

Shuvuuia deserti, this creature had muscular arms, a single claw on each hand, and long legs. The creature’s hearing and night vision was a lot better than other dinosaurs and even the majority of today’s birds. In fact, it has been compared to owls. While the remains were found in the middle part of the 1990s, experts only recently conducted in-depth analysis on its inner ear bones. During their analysis, Jonah Choiniere from the University of the Witwatersrand in South Africa as well as his colleagues found that the creature’s inner ear contained a very big lagena. This structure was responsible for how well it could hear and the larger it was, the better hearing creatures had. But this one in particular was much larger than any they have previously found in any type of dinosaur.
