Dromaeosaurus albertensis Dromaeosaurus (play /ˌdrɒmiːɵˈsɔrəs/) was a genus of theropod dinosaur which lived during the Late Cretaceous period (middle late Campanian), sometime between 76.5 and 74.8 million years ago, in the western United States and Alberta, Canada. The name means 'running lizard'. Dromaeosaurus was a small carnivore, about 2 m (6 ft 7 in) in length and 15 kg (33 lb) in weight. Its mouth was full of sharp teeth, and it had a sharp "sickle claw" on each foot. It lived during the Campanian stage of the Late Cretaceous, however, some fragmentary remains such as teeth which may belong to this genus have been found from the late Maastrichtian age Lance and Hell Creek Formations, dating to 65.5 million years ago. Dromaeosaurus had a relatively robust skull with a deep snout. Its teeth were rather large and it had only nine of them in the maxilla. In Dromaeosaurus albertensis, a vein at the back of the head, the vena capitis dorsalis, drains the front neck muscles through two long canals running to the posterior surface of the brain. ![]() 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. _____________________________________________________________________

My bets are on Dromaeosaurus 65/35 The Dromaesaurus was probably as agile and possesed bone-damaging teeth and bite strength. It even possesed an equally deathly claw, pretty much like Utahraptor, this factors suggest that this animal hunted deathlier prey than Velociraptor, and perhaps suggest that this animal was indeed an opportunist feeder that scavenged a bit more than V. mongoliensis. I think people tend to underestimate the relevance of the jaws in this kind of conflict. |

^how do you know that it posessed equally deadly claws? And that its teeth manage to puncture bone does not mean it had a powerful bite force. First of all, the dromaeosaur in question was Deinonychus. And secondly, many forces while feeding or killing can drive a tooth into bone, not just bite force. Dromaeosaurid mandibles don’t appear to be consistent with bone-puncturing adductor forces. |

Are you sure it's not 53.6% ? |

Same size,agility,body but dromeosaurus has more robust skull.55/45 for dromeosaurus. |

Isn't Dromaeosaurus also slightly bigger? |

Agreed,they were larger but no terrestrial apex predator was going to be engaged in any way shape or form due to their added length. |

Drom wins as it is larger and essentially an upgrade from the other raptor imo. |
