Flying VelociraptorsDeinonychosauria is one of the most apreciated dinosaur clades, but more often than not for quite erroneous reasons. The classical perception of predatory, super-intelligent giant "lizards" has not died yet, depicting creatures that are less real and more twisted fantasies of delluded minds. Instead of yet another breed of mythological dragon, dromaeosaurs and troodontids were normal animals, but yet quite unique in that they represent the avian prototype, the type of animal from which modern birds emerged. And like their surviving cousins, they too had an advantage over other dinosaurs: the air.Flying Velociraptors in Academic Essays

The close relationship between deinonychosaurs and Aves/Avialae has led since very early to the speculation that troodontids, dromaeosaurs and birds share a common, flying ancestor. Indeed, the famous generic basal avian, Archeopteryx, is very similar to basal troodontids, and the earliest troondontids and one entire linage of dromaeosaurids, Microraptorinae, as well as Rahonavis

1- Deinonychosaurs, much like megapodes and pterosaurs, had slow growth rates, and might had demonstrated superprecocial behaviour, implying that not only were the young independent, but also volant. By consequence, most if not all of Deinonychosauria engaged in aerial behaviour at least during the earliest part of their lives.
2- The widespread distribution of deinonychosaurs suggests that, much like the contemporary birds and pterosaurs, flight allowed them to colonise areas other theropods couldn't.
3- The absence of a well developed sternal keel, capacity of raising their forelimbs much above the back and of (in some cases), asymmetrical feathers does not mean flightlessness because several species developed what appear to have been cheap replacements.
4- Both Microraptor and Rahonavis demonstr
