Using remnants of fossilized trees, scientists and an artist figured out what the forest looked like long before humans existed.

By looking at the eye bones and ear canals of extinct dinosaurs, researchers show that a small ancient predator likely hunted at night and had senses as good as a modern barn owl.

Using the incredible wealth of fossil data and a modern ecological theory, researchers estimated population density for the extinct apex predator.
