Deinonychus and its kin - called dromaeosaurs - only stood on two toes, with their wicked sickle claws held off the ground. ❋ Unknown (2011)
Increasingly they agree on an even more surprising conclusion: that birds, rather than meriting a separate class, Aves, in the scientific organization of life, should be classed in Reptilia, within the Dinosauria, as the very successful surviving dromaeosaurs. ❋ Sy Montgomery (2010)
Even so, companies that recycle old artwork still try and sneak in scaly-skinned dromaeosaurs if you let them. ❋ Darren Naish (2006)
So, artists, feel free to depict baby dromaeosaurs running around with feather or stick toys in their mouths. ❋ Darren Naish (2006)
True feathers, so far as we know, were restricted to maniraptorans (the theropod clade that includes oviraptors, dromaeosaurs and birds), but simpler, filament-like integumentary structures appear to have evolved much earlier within theropod history, probably at or around the base of Coelurosauria. ❋ Darren Naish (2006)
A 90-million-year-old dinosaur recently discovered in Patagonia demonstrates that dromaeosaurs, carnivorous theropods that include Velociraptor, originated much earlier than previously thought. ❋ Unknown (2005)
This finding implies that flight may have evolved twice: once in birds and once among this group of Gondwanan dromaeosaurs. ❋ Unknown (2005)
Basically the authors are saying that, with their new find, in order for Archaeopteryx to be considered part of Aves, the dromaeosaurs and Troodons are all birds as well. ❋ Unknown (2005)
Feduccia 2002 concluded that the feathered dromaeosaurs should send “all those involved in the debate on bird origins back to the drawing board.” ❋ Unknown (2005)
He might prefer to start his argument over, given that he has spent years arguing that dromaeosaurs are completely unlike and unrelated to birds. ❋ Unknown (2005)
That is, Feduccia 2002 hypothesizes that dromaeosaurs are birds that are extraordinarily convergent with theropod dinosaurs, and that birds, including dromaeosaurs, originated from an early archosaurian ancestor and are still not closely linked to theropod dinosaurs. ❋ Unknown (2005)
Velociraptors were small carnivorous dinosaurs, like oviraptors and dromaeosaurs, animals that were long thought to steal eggs. ❋ Crichton, Michael, 1942- (1991)
Just last month palaeontologists Alexander Mudroch and colleagues reported over 120 impressions left by Deinonychus-sized dromaeosaurs in the Mid-Jurassic strata of Niger. ❋ Unknown (2011)
So many fantastic and terrifying dinosaurs have been found - dromaeosaurs with double sickle-claws (Balaur), Allosaurus-cousins with sail backs (Concavenator), crocodile-snouted hunters (Baryonyx), and others - that the I think the show's creators would have done better to draw inspiration from actual dinosaurs rather than trying to dress up a Deinonychus. ❋ Unknown (2011)
Samrukia was conceivably in danger from tyrannosaurs, dromaeosaurs and other predatory dinosaurs of the region, Naish said. ❋ Unknown (2011)
The discovery of Hesperonychus is the first sign of small carnivorous dinosaurs in North America and also extends the timeframe of small, birdlike dromaeosaurs known as the Microraptorinae in the fossil record by approximately 45 million years. ❋ Unknown (2009)
New theropods - particularly bird-like coelurosaurs (like dromaeosaurs) and big non-coelurosaurian tetanurans (like allosauroids) - make the news all the time, but ornithischians consistently draw the short straw. ❋ Unknown (2009)
Aardonyx, Tawa, the proposal of venomosity in dromaeosaurs, and all those million other recent dinosaur stories that made the newswires. ❋ Unknown (2009)
To their credit, Quick & Ruben (2009) do note that some birds (including kiwis, emus and the extinct elephant birds and mihirungs) have very small sterna that don't extend as far posteriorly as the abdominal air-sacs: these sterna are actually smaller, compared to trunk length, than those of such non-avian saurischians as dromaeosaurs and diplodocoid and macronarian sauropods (Wedel 2007). ❋ Unknown (2009)
