Leptoceratops (meaning 'little-horned face' and derived from Greek 'lepto-/lepto-' meaning 'small', 'insignificant', 'slender', 'meagre' or 'lean', 'kerat-/kerat-' meaning 'horn' and '-ops/ops' meaning face), is a genus of primitive ceratopsian dinosaurs from the late Cretaceous Period (late Maastrichtian age, 66.8-66 Ma ago) of what is now Western North America. Their skulls have been found in Alberta, Canada and in Wyoming.
Leptoceratops could probably stand and run on their hind legs: analysis of forelimb function indicates that even though they could not pronate their hands, they could walk on four legs. Leptoceratops was around 2 metres (6.6 ft) long and could have weighed between 68 to 200 kilograms (150 to 441 lb).
