''Anchiceratops'' ( ) is an extinct genus of chasmosaurine ceratopsid dinosaur that lived approximately 72 to 71 million years ago during the latter part of the Cretaceous Period in what is now Alberta, Canada. ''Anchiceratops'' was a medium-sized, heavily built, ground-dwelling, quadrupedal herbivore that could grow up to an estimated long. Its skull featured two long brow horns and a short horn on the nose. The skull frill was elongated and rectangular, its edges adorned by coarse triangular projections. About a dozen skulls of the genus have been found. ==Etymology== The genus name ''Anchiceratops'', means "near horned face", and is derived from the Greek words "anchi" (αγχι-) meaning "near", "keras" (κερας) meaning "horn", and "ops" (ωψ) meaning "face". ''Anchiceratops'' was described and named by American paleontologist Barnum Brown, in 1914, as he believed that this dinosaur represented a transitional form closely related to both ''Monoclonius'' and ''Triceratops'' and intermediate between them, but closest in the development of the skull frill to the latter, hence the generic name meaning "near ''Ceratops''". The type and only valid species known today is ''Anchiceratops ornatus'', whose name refers to the ornate margin of its frill.
