Quick Summary

Torosaurus is a genus of dinosaurs belonging to the suborder Ceratopsia. This dinosaur is known from the Laramie formation.1

While Torosaurus is a distinct genus, it is often discussed in relation to Triceratops. Triceratops was a large, plant-eating dinosaur from the late Cretaceous Period, known for its frill and three horns. Some paleontologists hypothesize that Torosaurus may represent a more mature life stage of Triceratops, distinguished by a larger, thinner frill with two large openings. However, this theory is still debated within the paleontology community.2
