A TINY dinosaur that lived in the desert had extraord-inary vision and owl-like hearing that enabled it to hunt in the dark, new research has found. Scientists have long wondered whether theropod dinosaurs – the group that gave rise to modern birds – had sensory adaptations similar to those of birds which enable them to hunt prey at night. A new study sought to investigate how the vision and hearing abilities of dinosaurs and birds compared and discovered that a theropod named Shuvuuia, part of a group known as alvarezsaurs, had both extraordinary hearing and night vision. The international team of researchers used CT scanning and detailed measurements to collect information on the relative size of the eyes and inner ears of nearly 100 living bird and extinct dinosaur species.
