The endocranium examinations also further cemented the theory that the dromaeosaur was an agile, swift predator. Fossil evidence suggesting Velociraptor scavenged also indicates that it was an opportunistic and actively predatory animal, feeding on carrion during times of drought or famine, if in poor health, or depending on the animal's age.

Ostrom noted the small body, sleek, horizontal posture, ratite-like spine, and especially the enlarged raptorial claws on the feet, which suggested an active, agile predator. [2] "Terrible claw" refers to the unusually large, sickle-shaped talon on the second toe of each hind foot. The fossil YPM 5205 preserves a large, strongly curved ungual.
In 1998, Kenneth Carpenter suggested another scenario in which the multiple wounds delivered by the Velociraptor on the Protoceratops throat had the latter animal bleeding to death. As a last effort, the Protoceratops bit the right hand of the predator and trapped it under its own weight, causing the death and eventual desiccation of the ...

Its anatomy indicated that it was an active predator that was likely warm-blooded, in marked contrast to the then-prevailing image of dinosaurs. [59] Concurrently, Robert T. Bakker published a series of studies that likewise argued for active lifestyles in dinosaurs based on anatomical and ecological evidence (see § Physiology ), [ 62 ] [ 63 ...
At that size, Linheraptor would have been a fast and agile predator, perhaps preying on small ceratopsians. [5] Like all dromaeosaurids, it had an elongated skull, a curved neck, an enlarged toe claw on each foot, and a long tail; Linheraptor was bipedal and carnivorous. The large toe claws may have been used for capturing prey. [5]
Bonaparte originally assigned Velocisaurus to a family of its own, the Velocisauridae.A study of theropod relationships by Fernando Novas and Sebastian Apesteguia in 2003 showed that Velocisaurus was a close relative of the strange ceratosaur Masiakasaurus.
Velociraptor has major roles in the novels and the films, both of which depict it as an intelligent pack hunter that is bigger than its real-life counterpart. [32] The franchise's Velociraptors are actually based on the larger Deinonychus, [293] although Crichton used the name Velociraptor because he thought it sounded more dramatic. [294]
