Leptoceratops (meaning 'Thin-horned face' and derived from Greek lepto-/λεπτο- meaning 'small', 'insignificant', 'slender', 'meagre' or 'lean', kerat-/κερατ- meaning 'horn' and -ops/ωψ meaning face),[1] is a genus of leptoceratopsid ceratopsian dinosaurs from the late Cretaceous Period (late Maastrichtian age, 68.8-66 Ma ago[2]) of what is now Western North America. Their skulls have been found in Alberta, Canada and Wyoming.[3][4]
