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). ____________________________________________________________________ Dark allosaurus Oct 27 2012, 03:24 AM utahraptor vs gastonia or some other ankylosaur

Friend of the fish Posts: 3,395 Group: Members Member #223 Joined: Mar 4, 2012	i think the length and size of the utahraptor may be a problem because it is less agile than it's smaller cousins, and will therefore have a harder time dodging that spiky tail. If i'm not mistaken gastonia looks more agile than the heavily armored ankylosaurus, and would have an easier time hitting the raptor, not to mention the spikes on the back will prevent the utahraptor jumping onto it. The only way i see utahraptor winning is if it gets good bit on neck or head otherwise it's unlikely that it will kill gastonia. Gastonia 80/20. Imo a pack vs a bigger ankylosaur would be a more interesting fight.

Friend of the fish Posts: 3,395 Group: Members Member #223 Joined: Mar 4, 2012	Malgus Nov 3 2012, 10:02 AM That size comparison is way off. The Gastonia was twice as heavy as the Utahraptor. Gastonia was heavier, but utahraptor is longer and taller which is clearly visible in the comparison.

Omnivore Posts: 1,252 Group: Members Member #559 Joined: Aug 26, 2012	Malgus Nov 3 2012, 10:02 AM Gastonia wins! That size comparison is way off. The Gastonia was twice as heavy as the Utahraptor. Size comp is just fine, Utah 6.75 meters, Gastonia 4.5 meters. Gastonia is squat and wide, but probably didn't weigh a ton. Maybe 1000-1200 lbs.
