This dinosaur roamed North America 78 million years ago during the Cretaceous Period. Judiceratops fossils were discovered in Montana in 2013. Belonging to the chasmosaurine ceratopsid dinosaur family, Judiceratops is the oldest known species in that family.
Another well-known chasmosaurine dinosaur is the Triceratops which closely resembles the Judiceratops. Judiceratops had a large skull with a parietal bone frill. Two large horns protruded from its head, and one smaller horn sat on its nose like a rhinoceros. Judiceratops walked on all four legs and enjoyed a herbivore diet. Other species the Judiceratops shared an environment with include amphibians and bony fish.
