Protoceratops andrewsi Granger & Gregory, 1923) > Protoceratops hellenikorhinus (Lambert, Godefroit, Li, Shang, and Dong, 2001)
A very weird protoceratopsian based on numerous specimens from Bayan Madahu Formation in a growth series, Protoceratops hellenikorhinus is larger than Protoceratops andrewsi, the frill has a chevron-shaped distal margin, kind of like a lot of chasmosaurines, the jugal horn is absolutely enormous, though more of a tongue-shaped thing than a real, pointed \\\\\\\\\\\\\\\"horn,\\\\\\\\\\\\\\\". Males have a more pronounced nasal horn, which is split into two small side-by-side horns and the palpebral sticks up well above the eye and just behind the nasal horn.
IMM 95BM1-1, nearly complete skull (male) Paratype IMM 96VM1/4, almost complete skull from the same locality. Other referred material: IMM 96BM5/5, IMM 96BM1/1, IMM 98BN1/7, IMM 96BM5/2, IMM 96MB5/3, IMM 96BM6/1, various partial skulls; IMM 96BM6/4, skull being associatedwith a series of caudal vertebrae and a right hindlimb.
