Utahraptor ostrommaysorum Utahraptor (meaning "Utah's predator" or "Utah thief") is a genus of theropod dinosaurs, including the largest known members of the family Dromaeosauridae. Fossil specimens date to the upper Barremian stage of the early Cretaceous period (in rock strata dated to 126 ± 2.5 million years ago). It contains a single species, Utahraptor ostrommaysorum. The holotype specimen of Utahraptor is fragmentary, consisting of skull fragments, a tibia, claws and some caudal (tail) vertebra. These few elements suggest an animal about twice the size of Deinonychus. Like other dromaeosaurids, Utahraptor had large curved claws on their second toes. One claw specimen is preserved at 22 centimetres (8.7 in) in length and is thought to reach 24 centimetres (9.4 in) restored. The largest described U. ostrommaysorum specimens are estimated to have reached up to 7 m (23 ft) long and somewhat less than 500 kg (1,100 lb) in weight, comparable to a grizzly bear in size. Some undescribed specimens in the BYU collections may have reached up to 11 m (36 ft) long, though these await more detailed study. Austroraptor cabazai Austroraptor ("Southern thief") was a genus of dromaeosaurid dinosaur that lived about 70 million years ago during the Cretaceous period in what is now modern Argentina. The type species for the genus, Austroraptor cabazai, was described in late 2008 by Fernando Novas of the Museo Argentino de Ciencias Naturales. The fossil specimen was discovered in the Late Cretaceous deposits located in the Río Negro Province of Argentina. The species was named in honor of Alberto Cabaza, who founded the Museo Municipal de Lamarque where the specimen was partially studied. Considered large for a dromaeosaur, Austroraptor cabazai measured around 5 metres (16 ft) in length from head to tail. It is the largest dromaeosaur to be discovered in the Southern Hemisphere. Particularly notable about the taxon were its relatively short forearms, much shorter in proportion compared to those of other members of its family. The relative length of its arms has caused Austroraptor to be compared to another, more famous short-armed dinosaur, Tyrannosaurus. Weight: 365 kg (810 lbs). ![]() ____________________________________________________________________________

I wasn't commiting plagiarism. I simply pulled up an old post I made or part of it in which i put the relevant part in. In the full post I cited. SecondlyI know that, the point of denticles is to aid in ripping/tearing otherwise why would you have them? Thirdly I never said it was comparable, just shows their teeth tear flesh contrary to the specific part you quoted. Lastly their jaws worked like jacknives. Even todays BOP use their (bites) when killing to paralyze the nervous system of their prey which is still effective nonetheless. Perhaps I should have made it extremely clear why I posted that no?

As of the time of this posting the posts with the name Headden in them, as well as the posts with the part you quoted are comfortably accessible via the search function and none of them has you giving credit (It could be that I missed it though you are free to point out the post but I think every reader would prefer it to not be edited recently). But this and your answer is irrelevant to the problem that you cited yourself with Headden's text. It makes no difference that you gave him credit earlier as most readers will not make the connection to any earlier post. E.g.: Cutting? Piercing? I think that Fowler et al. meant exactly the function described in the part you cited. It is very clear from the context that they make a distinction between the function the teeth fulfilled in other macropredatory theropods and Dromaeosaurs, with the first having a function comparable to that of varanids, something they explicitely denoted as tearing through flesh, while Headden used tearing in a more broad context, indicating exactly the same function as Fowler et al. in his description namely ripping off small junks of flesh. So the only contradiction you have found was one of word usage - not one of content. Why is this relevant? Clear would have helped enough. Edited by coherentsheaf, Apr 24 2013, 06:41 AM.

Utahraptor has nearly every conceivable advantage. It wins 90% of the time. |

Mismatch, Utahraptor completely obliterates the piscivore. |

Significant weight advantage+significantly better weaponry= great mismatch. |

EXTREME mismatch in favour of the Utahraptor. Utah is bigger, and has WAY (way, way) better weaponry than the Austroraptor. Austroraptor has very small teeth and small claws with very small arms. Will do almost nothing to a creature bigger, with more killer instinct and better weaponry than itself. |

Utah raptor: slightly bigger and more (deadly) weaponry. |

Actually I'm voting the austroraptor because his size and speed would be better for this battle

Utahraptor is rather significantly larger. And speed isn't going to help austroraptor, when its already completely outmatched in every way in the weaponry department. |

Agility matter more in this fight as it is close combat. Utahraptor has a significant size and weaponry advantage so it wins this fight about 65% |

its actually likely that it's even more then that. utahraptor was superier in possibly every way when it comes to weaponry. even the robustness of utahraptor possibly outclasses every dromaeosaur species at parity |

Yeah thats probably right about how robust Utahraptor was, but I think Achillobator or another raptor closely related would be about as robust. Utahraptor 80% |

actually no, utahraptor was the most robust in propotion to body size out of any raptor so far greatly due to it's size. based on scott hartmans newest utahraptor silohette, utahraptor was a creature that relyed more on strength and power then speed and agility. |
