Judiceratops possessed two large horns over its brow and a smaller horn on its nose. It appears to have spent much of its days peacefully feeding on low-growing vegetation, although one wonders if the horns rammed into something or someone every now and then.
The new dino is one of at least 18 closely related species in and around the Montana region. It's expected that more such dinosaurs will be found there in future.
"We keep finding new species, because cerotopsids - horned dinosaurs - evolved so rapidly," explained Longrich. "These species show up for just a couple million years, or even a far shorter time, before another species replaces it. As you move up into younger rocks or down into older rocks, you get new species and no longer see the old ones. There was a lot of turnover."

That must mean the environment there changed a lot over the years, with the dinosaurs evolving in response to the changes.
As for the name Judiceratops tigris, it refers to the site where the fossils were found - in the Judith River Formation of Hill County, Mont. - and to the Greek words "ceras" (horn) and "ops" (face).
