Research shows that five three-horned dinosaurs lived, and died, together
A team from Naturalis Biodiversity Center in the Netherlands was looking for a Tyrannosaurus in the summer of 2013 in Wyoming. Instead, they found a Triceratops: the famous dinosaur with the three horns and the large neck frill. And then they found another one. And another one. And more. The dig turned into a project that would last for more than 10 years.
