酷東西

趣味知識

Judiceratops had unusual teardrop-shaped horns above its eyes, a shape not seen in other horned dinosaurs.1

Its frill had large wing-like hornlets on the sides and small bumps on the back edge.1

Judiceratops lived alongside many other dinosaurs, including the horned dinosaurs Albertaceratops and Medusaceratops, and the predator Gorgosaurus.1

The first fossils of Judiceratops were found in a place called Skull Crest in Montana.4

Scientists think Judiceratops evolved quickly, because it appears in the fossil record soon after the earliest horned dinosaurs in North America.1

Judiceratops is known from only a few skull fragments, so its full size is still unknown.2
