Thalassodromeus Pterosaur Profile. [16][20], Paleofauna that were contemporaneous with the dromaeosaurid in the Upper Yellow Cat Member included numerous dinosaurs, such as the iguanodonts Hippodraco and Cedrorestes, the other theropods Martharaptor and Nedcolbertia, the nodosaurid Gastonia, and the sauropods Cedarosaurus and Moabosaurus. Merkmale. It was a heavy-built, ground-dwelling, bipedal carnivore. Like other dromaeosaurine dromaeosaurids, it may have also relied heavily on its jaws to dispatch prey—more so than other types of dromaeosaurids, such as velociraptorines. [1] Like other dromaeosaurids, Utahraptor had large curved claws on their second toes. Utahraptors are the largest raptors ever found. The holotype of Utahraptor is fragmentary, consisting of skull fragments, a tibia, claws and some caudal (tail) vertebra.The few elements suggest an animal about twice the size of Deinonychus. Kirkland, J.I. [21][22][23] The only known mammal from the Upper Yellow Cat Member is Cifelliodon. 1993. ==References ==References==, Template:Commons category Sculptor Raymond Persinger was included in James Kirkland's original abstract referencing Mr. Persinger's concepts regarding the claw structure. vo:Utahraptor [6] In 2016 Rubén Molina-Pérez and Asier Larramendi estimated the largest specimen (BYU 15465) at 4.65 m (15.3 ft) long, 1.5 m (4.9 ft) tall at the hips and 280 kg (620 lb) in weight. James Kirkland, Robert Gaston, and Donald Burge discovered Utahraptor in 1991 in Grand County, Utah, within the Yellow Cat and Poison Strip members of the Cedar Mountain Formation. It contains a single species, Utahraptor ostrommaysi, which is the largest-known member of the family Dromaeosauridae. de:Utahraptor This reconstruction of the giant dromaeosaurid Utahraptor was the most challenging I've done in quite some time, but I'm fairly happy with the results. Based on the presence of new palynoflora, Middle Berriasian–Early Hauterivian ages were provisionally assigned. Dinosaurpedia Wiki is a FANDOM Lifestyle Community. It is classified in the subfamily Dromaeosaurinae, which is found in the clade Eudromaeosauria.

Utahraptor (meaning "Utah's thief") is a genus of large dromaeosaurid dinosaur that lived in North America during the Early Cretaceous period. The specific name, ostrommaysi, is in honour to John Ostrom for his investigations on Deinonychus and its bird relationships, and Chris Mays, who helped in the research of Utahraptor by founding Dinamation. [1], It was also suggested that dromaeosaurids such as Velociraptor and Deinonychus, relied on their hand claws to handle prey and retain balance while kicking it, contrary to this, Utahraptor with a much greater weight, may have been able to deliver kicks without the risk of losing balance, freeing the hands and using them to dispatch prey. According to the authors of its description, Utahraptor had an important ecological role as a major carnivore of the paleofauna of the present-day Arches region during the Early Cretaceous, and could probably attack prey larger than itself. 2007. It lived from 131 to 126 mya during the Barremian Stage of the early Cretaceous and … Utahraptor had sharp, bladelike teeth for biting chunks off its prey.. Hooked claws. Instead, it is advised you aim for their neck vertebrae or spine, as this is just as likely to take one down in one shot. fi:Utahraptor Because of their relatively small size, getting a successful heartshot is difficult. any human (as is portrayed within the Jurassic World films). As Large as a human hand! "Utahraptor", meaning 'Utah Theif', was only known from fragments, but scientists estimate it to be about 15 - 17 feet long, and around the height of an average adult male human. [28][29] Bakker's anthropomorphosis of the titular Red was particularly praised. Utahraptor is the oldest known, and largest, of the dromaeosaurids. [1][2] Some undescribed specimens in the BYU collections may have reached up to Template:Convert long, though these await more detailed study. The big bones, too, bring surprises. Utahraptor was a very large dromaeosaur, one of the biggest members of its' family. [20] During the description of Mierasaurus, it was interpreted that there was also a waterlogged bog-like environment. Examination of the fossils are ongoing after a decade of excavation, but if Kirkland is correct, it may be one of the best preserved predator traps ever discovered. ; Norell, M.A. File:Utahraptor scale.png. [1] The paleontologist Thomas R. Holtz estimated that Utahraptor existed between 130 million and 125 million years ago. Under this reasoning, ostrommaysorum has no valid use and the original spelling ostrommaysi does not need an emendation. I would say no they would not be able to do it. Other alternative and also invalid spellings were used in scientific literature, such as ostromaysi, ostromaysorum, ostromayssorum, ostromayorum and ostrommaysori. Illustration of a comparison of the size of an adult utahraptor with an average adult male human (1.8 meters) Image Editor Save Comp. [1] Earlier, it had been intended to name the species "U. spielbergi" after film director Steven Spielberg, in exchange for funding paleontological research, but no agreement could be reached on the amount of financial assistance. Its tail would stretch out behind it to stabilize the massive animal at high speeds. Each inside toe had a large hooked claw (about 10 inches long) that was controlled by a strong tendon. Sauropelta Profile on White. th:ยูทาห์แรปเตอร์ Published ... Do you really need to slave over that worthless vestigial part of the human brain responsible for anger? [34], College of Eastern Utah Prehistoric Museum, International Code of Zoological Nomenclature, "A large dromaeosaurid (Theropoda) from the Lower Cretaceous of Eastern Utah", "Was Dinosaurian Physiology Inherited by Birds? [1] Radiometric dating has shown that these parts of the Cedar Mountain Formation were deposited about 126 million years ago. [15], Kirkland et al. Information [edit | edit source]. [3] The premaxilla (the front of the upper jaw) of a baby Utahraptor is about the size of a penny, for example. [1], In 2015, Utahraptor was found to be closely related to the smaller Dromaeosaurus and the giant Mongolian and North American dromaeosaurid genera Achillobator and Dakotaraptor:[14], The cladogram below is the result of a cladistic analysis conducted by Cau et al. Although this spelling has been largely used by other authors, the genus Utahraptor was originally coined with the type species U. ostrommaysi and given that the International Code of Zoological Nomenclature offers no provision for forming a genitive form from two persons with different names, Costa and Normand conclude that the original spelling ostrommaysi has to be regarded as an arbitrary combination of letters and not a correctly formed genitive form. Added to this, adult Utahraptors are more likely to have preferred ‘pack hunting’, so a single human would have stood ‘no chance at all’; with only a ‘tribe … But an adult Utahraptor, would outclass (i.e. he:יוטרפטור Like others dromaeosaurs, Utahraptor was a fierce hunter and had long arms with sharp, hooked claws, which were used for grabbing prey. The Lower Cretaceous Cedar Mountain Formation, eastern Utah: the view up an always interesting learning curve. ru:Ютараптор The Utahraptor character is meant to serve as a "questioning and interrogative" interlocutor in the comic's sometimes bizarre discussions of life and philosophy. [12] So far, there is nothing to suggest that feathers were lost in larger, more derived species of dromaeosaurs. These elements have huge proportions compared to other dromaeosaurids, suggesting an animal about twice the length of Deinonychusor, surpassing it in a 100%. The second pedal ungual is preserved at 22 cm (8.7 in) in length and is estimated to reach 24 cm (9.4 in) restored. [1] Like other dromaeosaurids, Utahraptor had a huge curved claw on the second toe; one is preserved at Template:Convert in length and is thought to reach Template:Convert restored. [8] The type specimen is currently housed at the College of Eastern Utah Prehistoric Museum, although Brigham Young University currently houses the largest collection of Utahraptor fossils. Feathers were very unlikely to have evolved more than once, so assuming that any given dromaeosaurid, such as Utahraptor, lacked feathers would require positive evidence that they did not have them. Usually animals of this size end up with plainer colours and less distinctive markings, and a lot of extra-large predatory birds … Image size. The deposition occurred between 139 ± 1.3 million to 134.6 ± 1.7 million years ago, or, Berriasian to Late Valanginian stages. An adult dinosaur of this type likely weighed about 900 pounds and stretched for 9 meters, with much of that being occupied by the tail and neck. pl:Utahraptor sp., A New Sauropod From The Early Cretaceous (Aptian) of North America", 10.1671/0272-4634(2006)26[1005:ABNFTC]2.0.CO;2, "New Dromaeosaurids (Dinosauria: Theropoda) from the Lower Cretaceous of Utah, and the Evolution of the Dromaeosaurid Tail", Stolen Utahraptor recovered in Australian Capital Territory, https://en.wikipedia.org/w/index.php?title=Utahraptor&oldid=1005821784, Early Cretaceous dinosaurs of North America, All Wikipedia articles written in American English, Articles with unsourced statements from February 2021, Creative Commons Attribution-ShareAlike License, This page was last edited on 9 February 2021, at 15:58. The fossils may further reveal aspects into the behavior of Utahraptor, such as whether it might have hunted in groups like Deinonychus was believed to have done. [1], Size of largest described (green) and reported (gray) specimens compared to a human, The holotype of Utahraptor is fragmentary, consisting of skull fragments, a tibia, claws and some caudal (tail) vertebra. Similar sites such as the Cleveland-Lloyd Quarry and California's La Brea Tar Pits house such predator traps. [1] Description Size of largest described (green) and reported (gray) specimens compared to a human The holotype of Utahraptor is fragmentary, … PMID 17885130. Toe claw. [5] In multiple occasions, the Yellow Cat Member has been dated to Barremian-Aptian ages. no:Utahraptor Like others dromaeosaurs, Utahraptor was a fierce hunter and had long arms with sharp, hooked claws, which were used for grabbing prey. and Madsen, S.K. A Utahraptor has a +8 racial bonus on Hide, Jump, Listen, and Survival checks, and a +11 on Spot checks due to its Human-comparable color vision. [9] The program portrayed Utahraptor with several anatomical inaccuracies including pronated hands, and depicted it living in Europe when the only fossils of Utahraptor have been found in western North America. [1][4] [10], Although feathers have never been found in association with Utahraptor specimens, there is strong phylogenetic evidence suggesting that all dromaeosaurids possessed them. Pounce (Ex): If a Utahraptor charges, it can make a full attack Skills . Turner, A.H.; Makovicky, P.J. Template:ItalictitleTemplate:Taxobox Utahraptor wird von Kirkland und Kollegen auf eine Länge von etwa 7 Metern und ein Gewicht von 500 kg geschätzt. The Quarterly Review of Biology 77: 261–295. This evidence comes from phylogenetic bracketing, which allows paleontologists to infer traits that exist in a clade based on the existence of that trait in a more basal form. in 2012, Utahraptor differs from other dromaeosaurids in: an elongate nasal process of the premaxilla; a distal end of metatarsal III that is smooth, not ginglymoid; an L-shaped quadratojugal without a posterior process; the presence of a well developed notch between the lesser trochanter and greater trochanter; and dorsal vertebrae that lack pleurocoels. [24], Other non-dinosaur taxa known from the Member include the fish Ceratodus and Semionotus, the turtles Glyptops and Trinitichelys, Aquatilavipes (fossilized bird tracks), the rhynchocephalian Toxolophosaurus, and the indeterminate remains of hybodontid and polyacrodontid sharks. Fieldtrip Guidebook, Geological Society of America, Rocky Mountain Section. [1] In 2012, the paleontologist Thomas R. Holtz Jr. estimated its weight around 230 to 450 kg (500 to 1,000 lb), comparable to a grizzly bear. also suggested that the previously identified manual unguals of the specimens CEU 184v.294, BYU 9438 and BYU 13068 are indeed pedal unguals. The genus Microraptor is one of the oldest-known dromaeosaurids, and is phylo­genetically more primitive than Utahraptor. A trusty shotgun loaded with some buckshots is the best way to take them down. [16] In a 2001 study conducted by Bruce Rothschild and other paleontologists, two foot bones referred to Utahraptor were examined for signs of stress fracture, but none were found. Utahraptor size comparison - gg61501716 GoGraph Stock Photography, Illustrations, and Clip Art allows you to quickly find the right graphic. Model of the foot, showing specialized claw, A speculative reconstruction of Utahraptor lifestyles and behavior was presented in the 1999 BBC television series Walking with Dinosaurs. Utahraptor Size Comparison. [18], Utahraptor lived in the lower part of the Cedar Mountain Formation, a bed known as the Yellow Cat Member. Illustration of cretaceous, carnivore, male - 25353876 [5] Since Microraptor possessed feathers, it is reasonable to assume that this trait was present in all of Dromaeosauridae. [10] "Feather quill knobs in the dinosaur Velociraptor". English: A chart showing the approximate size of the dromaeosaurid Utahraptor compared to a human. "Four-winged dinosaurs from China." The holotype of Utahraptor, CEU 184v.86 consists of a second pedal ungual, with potentially assigned elements from other specimens: pedal ungual CEU 184v.294, tibia CEU 184v.260 and premaxilla CEU 184v.400. Kirkland speculated that the Utahraptor pack attempted to scavenge carrion or attack helpless prey mired in quicksand, and were themselves mired in the attempt to attack the herbivore. Template:Portal [20], Utahraptor was unearthed from the Yellow Cat Member, which during the Berriasian to Late Valanginian was a semiarid area with floodplain prairies, riverine forests, and open woodlands predominated by conifers (Pinophyta), ferns (Polypodiopsida), hornworts (Anthocerotophyta) and other vascular plants. [1] Weve all seen the charts that attempt to show an animals size compared to that of an average human but its very hard to truly comprehend an animals size compared to a human based on those shaded figures. Also fossilized with the predators are the remains of at least one possible iguanodont herbivore. Utahraptor's vital zones.
