The same size of ''[[StockDinosaurs Velociraptor]]'' but with a shorter head and stronger jaws and teeth, ''Dromaeosaurus'' is less-frequently portrayed than the PowerTrio made up of ''Utahraptor'', ''Velociraptor'', and ''Deinonychus''. Despite this, ''Dromaeosaurus'' appears regularly in dino-books and has also made some apparitions in TV documentaries. If you see a dromaeosaurid interacting with ''TyrannosaurusRex'' or ''Triceratops'' in Late Cretaceous North America, it would be ''Dromaeosaurus'' [[note]]To be correct, however, ''Dromaeosaurus'' lived some million years before the end of the Cretaceous in which ''T. rex'' and ''Triceratops'' lived, but a dromaeosaurid that actually lived alongside ''T. rex'' and ''Triceratops'' was named in 2013: ''Acheroraptor''.[[/note]] -- unless the writers didn't know or just didn't care: some docus have shown ''Deinonychus'' in this role. ''WalkingWithDinosaurs'' dealed with the problem in a bizarre way: here, the dromaeosaurids are officially ''Dromaeosaurus''… but ''have the shape of Deinonychus''.

Together, ''Deinocheirus'', therizinosaurids & ''Gigantoraptor'' make a strange case: such overgrown birdlike theropods seem an only-Asian affair, and nobody knows why similar animals have never been found in North America (considering the strong similarity of the two faunas in the Late Cretaceous). Maybe could the competiton with the exclusively American Ceratopsids have prevented North-american maniraptoriformes to reach larger size?

size (though even that idea has problems, since we now know that there [[https://en.wikipedia.org/wiki/Sinoceratops were ceratopsians]] in Asia)?

Actually, every dromaeosaurid in the original series was a ''Deinonychus'', ''Utahraptor'' included -- which, even though their name clearly means “Utah thief”, were portrayed [[MisplacedWildlife living in Europe]] [[TheyJustDidntCare for some reason]]. And to make the ''Utahraptors'' and the ''Dromaeosauruses'' distinguishable, they show up [[PaletteSwap with a different coloration]]. In this show, ''Utahraptor''s are also portrayed in the way dromaeosaurids were once represented in paleo-art: naked-skinned, [[PantheraAwesome colored like big cats]], chasing an iguanodont [[ZergRush in packs]], jumping on it using their sickle-claws as spurs, and eventually killing it with (a quite exaggerated) ease. Many dino-books have made this thing UpToEleven with ''Dromaeosaurus'', depicting scenes in which these turkey-sized predators chase and kill in packs adult ''Edmontosaurus'' and ''Triceratops'' 500 times heavier. [[ScienceMarchesOn Current paleontology]] suggests that ''Dromaeosaurus'' and the other “raptors” hunted smaller (but still large) prey and only ate the carcasses of the giant herbivores. The bigger dromaeosaurs (''Utahraptor'' and ''Achillobator'') may have been able to take larger game then their smaller relatives; but likely they were more solitary then the much smaller ''Velociraptor'' and ''Deinonychus''. But stop now.

'''Wolverine-Claws dinosaur:''' ''[[http://en.wikipedia.org/wiki/Therizinosaurus Therizinosaurus]]''

''Therizinosaurus'' could be considered the Non Identical Twin of ''Deinocheirus'': it was a colossal yet awfully bird-like theropod, just like ''Deinocheirus''; specialized to a non-big-prey-based diet, just like ''Deinocheirus''; was discovered in Late Cretaceous rocks from Mongolia, just like ''Deinocheirus''; is known mainly from forelimbs and few other bits, just like ''Deinocheirus'' before 2014; entered the dinosaur list around the same time as ''Deinocheirus''; and, last but not least, it is another candidate for “the biggest theropod” title, [[MadnessMantra just like]] ''[[MadnessMantra Deinocheirus]]''! But, '''un'''like ''Deinocheirus'', ''Therizinosaurus'' was not a giant ornithomimosaur -- but still an equally huge freak.

Discovered in the 1950s but not recognized as a dinosaur until the 1970s, its forelimbs were slightly shorter but more powerful than those of the giant ornithomimosaur. But ''Therizinosaurus'' had an additional curiosity, one that made it [[AlwaysSomeoneBetter even more awesome]]: [[WolverineClaws three scythe-like claws]] on each hand (hence its name, “scythe lizard”), some ''as long as a human arm''. In short, it had the biggest nails known so far within the entire Animal Kingdom. One of these oversized claws was in fact the first known remain, and for several years, [[ScienceMarchesOn scientists thought it belonged to a giant marine turtle]].

With such poweful weapons, ''Therizinosaurus'' has received in the past the same treatment as ''Deinocheirus''. Some old drawings went as far as to show our “scythe-dino” as a giant carnosaur or deinonychosaur with ''sickle-claws'' on each foot (if ''Therizinosaurus'' was really shaped that way, it would really have been the most BadAss dinosaur one can imagine…). More accurate analyses made in the beginning of the 1990s definitively debunked these fantasies: we now know with a good level of sureness that ''Therizinosaurus'' was a bulky-bodied, round-bellied, and quite slow-moving animal, that used its claws mainly to pull down branches. Furthermore, its jaws were arguably weak with a rounded horny tip and small grinding teeth similar to those seen in its relative ''Segnosaurus''.

This obviously doesn't lessen its general coolness: even with this new shape, ''Therizinosaurus'' remains an odd-looking, powerful beast, and thanks its massive body, it might even be the biggest and heaviest theropod ever discovered, weighing even more than the famous ''[[StockDinosaurs Spinosaurus]]''. Like what we've long done with ''Deinocheirus'', we dino-fans are patiently waiting for new exciting remains of our "WolverineClaws-osaurus" being excavated.

Meanwhile, a special spinoff of ''WalkingWithDinosaurs'' from 2002 temporarily recreated our imagination in CGI: in the episode titled “''The Giant Claw''” Nigel Marven talks about ''Therizinosaurus'', [[LampshadeHanging lampshading]] its whole ScienceMarchesOn story from a mighty carnivore to a GentleGiant. Nigel is in Late Cretaceous Mongolia searching for the possessor of the eponymous “giant claw”, which the zoologist believes to have pertained to a fearsome predator. After goung through several adventures with other famous dinosaurs of the habitat (''Protoceratops'', ''Velociraptor'', etc.), Nigel witnesses a fight between ''Therizinosaurus'' and ''Tarbosaurus'': even though the former unexpectedly reveals itself to be a herbivore, it easily defeats the tyrannosaur by slapping it in the face with its scythe-claws, obligating the predator to flee. Finally, the [[RuleOfCool therizinosaur licks Nigel’s face]]. Really!

In many forms of dinosaur media, you'll frequently see generic raptors living alongside ''TyrannosaurusRex'' and ''Triceratops''. These raptors are typically named after someone in the PowerTrio of the [[StockDinosaur Stock Raptor]] family, ''Utahraptor'', ''Deinonychus'' or ''Velociraptor''. However, there is a small problem here: None of these raptors actually lived with ''T. rex'' or ''Triceratops''. ''Deinonychus'' and ''Utahraptor'' died out long before ''T. rex'' showed up, and ''Velociraptor'' lived at the same time, but on the other side of the planet (though it did live with a close relative of ''Tyrannosaurus''). For the longest time, this common stereotype was seen as inaccurate.

''Acheroraptor'' ("Plunderer of Acheron") was a small raptor, similar to ''Velociraptor'' in appearance, size and likely ecological niche that lived in the Hell Creek Formation at the very end of the Cretaceous. It most likely hunted small game. Later in 2015, another raptor known as ''Dakotaraptor'' was discovered to have been close to ''Achillobator'' in size and ''Deinonychus'' in appearance and niche. What's more, it had quill knobs on its hands and arms, a surefire sign of wing feathers.

Other Liaoning coelurosaurs showed up in the third episode "Dino-Birds" of the miniseries ''PrehistoricPark''. The chosen ones were: the buck-toothed oviraptorosaur ''[[http://en.wikipedia.org/wiki/Incisivosaurus Incisivosaurus]]'' because of its [[RuleOfFunny funny look]], the troodontid ''[[http://en.wikipedia.org/wiki/Mei_(dinosaur) Mei]]'', which has until 2015 detained the record of “the shortest-named dino” along with the alvarezsaurid ''Kol'' and the sauropod ''Zby'' - the former record-holders were the Australian ankylosaur ''Minmi'' and the oviraptorosaur ''Khaan'', the current one is the scansoriopterygid ''Yi'' (see below), and, naturally, the ever-present ''Microraptor''.[[note]] Note, however, that fossils of ''Incisivosaurus'' and ''Mei'' have not yet been found preserving soft tissues, unlike the other dinosaurs listed here. Nonetheless, being maniraptors, they almost certainly had feathers. Also, ''Microraptor'' is in fact known from a younger formation than the other dinosaurs mentioned here. Finally, some think that ''Incisivosaurus'' (known only from a skull) may be the same as ''Protarcharopteryx'' (known from a skeleton with a badly damaged skull.[[/note]] In “Dino-Birds”, Nigel Marven makes a TimeTravel to the Cretaceous China to save some ''Microraptor''s from extinction; before ending the mission, he encounters several ''Mei'' (referred to by their whole scientific name: ''Mei long'') apparently sleeping in the same bird-like position in which the type specimen was found fossilized (they were actually dead), while the other ''Mei long'' act as the “danger of the forest”, and to fit their fearsome better role, are [[RuleOfCool oversized]] [[ArtisticLicensePaleontology and lack feathers]].

Despite being a very recent find, ''Gigantoraptor'' has already recevied some mild media attention, appearing in paleo-documentaries like ''PlanetDinosaur'' and ''Series/DinosaurRevolution''. Its [[RuleOfCool awesome-sounding name]] could even make it a new member of the StockDinosaurs in the future.
