Periodo: Cretáceo Tardío

For many years, the Late Cretaceous dinosaur was a complete mystery to scientists. They had no idea what this creature looked or behaved like and only had a few fossilized bones to work with. That all changed in 1990, when part of its skull was discovered near Big Bend National Park in Texas. Scientists were able to study the teeth and other features that helped us learn more about this animal's diet, size, behavior and even where it lived.
