Nedoceratops

Nedoceratops (meaning "insufficient horned face") is a controversial genus of ceratopsid herbivorous dinosaur from the Late Cretaceousperiod Lance Formation of North America. It is known only from a single skull discovered in Wyoming. Its status is the subject of ongoing debate among paleontologists: some authors consider Nedoceratops a valid, distinct taxon, while others consider it to represent an ontogenetic (growth) stage of Triceratops and thus a synonym.[1]
