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 More Like This
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
Flying Velociraptors: take 2Previously, I have ventured into the possibility that deinonychosaurs in general might had been far more volant than previously thought. The key points of the previous article:Flying Velociraptors: take 2 in Academic Essays More Like This
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
Urge to flyThe forest floor layed silent; it was in the middle of the day, as iluminated as it could get, and the air was hot and stagnated. Only the sound of insects were heard, and occasionally the eerie call of a larger animal. In the canopy the sound of wings was heard, followed by the shrieks of a long tailed pterosaur, who flew across the forest. It then hoovered above the ground like a kestrel, and diving it caught a mammal, it then took off again and landed in a nearby branch, feasting on the furry prey. The winged beast was being observed by a quite different animal, bipedal and covered in down, probably not any bigger than a chicken. The animal quickly returned to its activity of searching for insects and other small prey, picking them with its toothed jaws. The scaly legs revolved the ground foliage as it searched for prey, stoping its search for undergrowth snacks once it heard an alrming sound.Urge to fly in Historical More Like This
