Velociraptor mongoliensis Velociraptor ( /vɨˈlɒsɨræptər/; meaning 'swift seizer')[1] is a genus of dromaeosaurid theropod dinosaur that existed approximately 75 to 71 million years ago during the later part of the Cretaceous Period. Two species are currently recognized, although others have been assigned in the past. The type species is V. mongoliensis; fossils of this species have been discovered in Mongolia. Smaller than other dromaeosaurids like Deinonychus and Achillobator, Velociraptor nevertheless shared many of the same anatomical features. It was a bipedal, feathered carnivore with a long, stiffened tail and an enlarged sickle-shaped claw on each hindfoot, which is thought to have been used to kill its prey. Velociraptor can be distinguished from other dromaeosaurids by its long and low skull, with an upturned snout. Velociraptor was a mid-sized dromaeosaurid, with adults measuring up to 2.07 m (6.8 ft) long, 0.5 m (1.6 ft) high at the hip, and weighing up to 15 kg (33 lb). The skull, which grew up to 25 cm (9.8 in) long, was uniquely up-curved, concave on the upper surface and convex on the lower. The jaws were lined with 26–28 widely spaced teeth on each side, each more strongly serrated on the back edge than the front—possibly an adaptation that improved its ability to catch and hold fast-moving prey. Protoceratops andrewsi Protoceratops ( /ˌproʊtoʊˈsɛrətɒps/; from Greek proto-/πρωτο- "first", cerat-/κερατ- "horn" and -ops/-ωψ "face", meaning "First Horned Face") is a genus of sheep-sized (1.5 to 2 m long) herbivorous ceratopsian dinosaur, from the Upper Cretaceous Period (Campanian stage) of what is now Mongolia. It was a member of the Protoceratopsidae, a group of early horned dinosaurs. Unlike later ceratopsians, however, it was a much smaller creature that lacked well-developed horns and retained some primitive traits not seen in later genera. Protoceratops had a large neck frill, which may have served to protect the neck, to anchor jaw muscles, to impress other members of the species, or combinations of these functions. Described by Walter Granger and W.K. Gregory in 1923, Protoceratops was initially believed to be an ancestor of the North American ceratopsians. Protoceratops was approximately 1.8 meters (6 ft) in length and 0.6 meters (2 ft) high at the shoulder. A fully grown adult would have weighed less than 400 pounds (180 kg). The large numbers of specimens found in high concentration suggest that Protoceratops lived in herds. ![]() Edited by Taipan, Oct 15 2017, 01:33 PM.

There's no evidence that the foot hasn't moved slightly through the million of years, so nothing conclusive can be inferred from it, really. I'll go with Protoceratops on a one on one basis. Ps the claw was only around two inches long. It's much smaller than a harpy talon, for example. |

33 lb raptor vs 400 lb ceratopsian? Mismatch in favour of Protoceratops. Velociraptor may have deadly weaponry but Proto has that nasty beak and can headbutt the raptor. IMO Deinonychus would be a better match, or else I might even request that |

One on One the Protoceratops wins easily, it is ten times the weight of the raptor and probably had a stronger bite. In my opinion it would take at least 3 velociraptors to pose a serious threat. |

Velociraptor gets demolished face-to-face, it has to use ambush, to take on a Protoceratops

Why odes everyone in that use a 1962 estimate for Protoceratops? The same guy also estimated an 80t Brachiosaurus! I would prefer scaling the estimate for a 1,4m Protoceratops to 2m. Than we have 70 kg. With a predator:prey ratio of 1:4,6 it looks much better for Velociraptor IMO, but it still would be rather chanceless. IMO, like a 200 kg cat vs a 900-1000 kg bovine. I think face to face the Prtoceratops wins with a propability of 80-90%, by ambush the Velociraptor probably wins 60/40. On some occasions, it could have killed an adult Protoceratops solo, like wolfes do it with Muskox sometimes, but I think this was far from normal. The Protoceratops in the fighting fossil was 1,3m long… Therefore I think Protoceratops wins with ease IMO. |

Protoceratops wins this 75% of the time. It's to massive for the Raptor. And that beak could inflic some serious damage. |

Even a 70 kilogram Protoceratops should win this the majority of the time. It would still be too large for a 33 pound Velociraptor. A 180 kilogram Protoceratops would be overkill IMO. The ceratopsian would headbutt and bite the dromaeosaurid to death. |

70 kg was for a 2 m Protoceratops, as I now know that Protoceratops was more like 1,8 m long, 50 kg sounds more realistic. Plus, broly posted evidence for a 25 kg Velociraptor, so this may be closer than I thought. P.S. A 180 kg Protoceratops could barely move. Edited by Jinfengopteryx, Sep 8 2013, 12:23 AM.

Show me this evidence for a 25 kilogram Velociraptor. |

A 50 kilogram Protoceratops is still 2x bigger than a 25 kilogram Velociraptor. I still favor the ceratopsian. |

I only said it would be closer than I thought. |

Protoceratops 50-55% of the time, being bigger and more powerful and having a deadly bite to counter the V-rap's claws. |
