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. Gastonia burgei Gastonia is a genus of nodosaurid dinosaur from the Early Cretaceous of North America, around 125 million years ago. Closely related to Polacanthus, it has a sacral shield and large shoulder spikes. It is also the first polacanthine dinosaur to have been mounted for display at the Denver Museum of Nature and Science, together with the related Gargoyleosaurus. This dinosaur was found in the same quarry as Utahraptor, the largest known dromaeosaurid. Named by James Kirkland in 1998 from material recovered in Grand County Utah, more complete material exists for Gastonia than for any other polacanthine ankylosaur. Unfortunately, a wealth of disarticulated material from a bonebed presents problems as it can be hard to tell how many spikes a particular Gastonia actually had. Gastonia was named after Robert Gaston, the discoverer of the genus. Robert Gaston is a paleoartist, who makes a living of creating museum quality casts and replicas of fossils for private and public collections. The type species, G. burgei, was found in rocks of the Cedar Mountain Formation (Yellow Cat member), which has been dated to 126 million years ago. Weight: 1 ton (900 kilos). ____________________________________________________________________

I see Gastonia doing the same as in JFC. |

That gastonia was bigger than its reality weight.

Well, gastonia is essentially a walking tank with spikes, much like its larger relatives. I don't really see how the Utahraptor could cause a lot of damage unless it knew where the less-armored points were. |

Gastonias armor was a paperweight compared to larger ankylosaurs. Utahraptor with a bit of effort shouldn't have any problems actually. It obviously would have evolved a method to kill gastonia since they coexisted. |

Yes, truly. But gastonia WAS about 900 pounds heavier. It wasn't as well-armored as its later relatives, but it was heavy and surely not defenseless. |

It was 900lbs heavier yet look how small it actually is. |

But imagine the damage that it could do if it charged full speed at its opponent. It may be small in size, but not mass. Depending on its greatest speeds, it could have had greater momentum than the Utahraptor due to a greater mass. But again, Momentum = Mass X Speed. So the only way it could have greater momentum was if it had grater speed, equal speed, or near speed to the Utahraptor. Edited by Godzillasaurus, Jan 9 2013, 11:55 AM.

Gastonia couldn't run fast.....which is why it was armored. |

Yes, I had doubts about that. If it COULD run fast, then it would surely have more momentum than the Utahraptor. |

Not momentum, if your speaking of ramming abilities, it would simply have more force behind the ram. Droms may not be built for speed but in a race between utahraptor and gastonia, my moneys on the drom. |

Gastonia is the only accurate dino in JFC. |

Tough fight. The sidewise poking spikes are pretty dangerous and it would be quite dangerous for the Utah to come near Gastonia. Even the head and neck region have spikes and hence they are not soft targets on Gastonia's body. The raptor has to pounce quickly and get the claw into the belly region to inflict a serious wound and the chance of getting hit by Gastonia while doing this is pretty high. Utahraptor can't jump onto Gastonia's back as there is every chance of getting mortally wounded. The raptor has to carefully take a few digs at Gastonia's soft underbelly and Gastonia will weaken and collapse. But there is a good chance of getting hit while doing this. 50/50 perhaps. |

Utahraptor wins this. Gastonia was a not very strong dinosaur. |
