But new Dutch research just completed suggests the iconic dinosaur did, indeed, move in herds.
A group of palaeontologists from the Naturalis Biodiversity Center in the Netherlands have made a discovery of a lifetime – a herd of five triceratops.
The team was searching for the remains of a Tyrannosaurus, in Wyoming, when they found the first Triceratops. And then, they found another one. And more.
The dig turned into a project that would last for more than 10 years and eventually, uncover 1,200 bones and fragments of at least five individuals.
