Linked to this issue of balance and coordination, the ‘terrible claw’ on each foot was clearly an offensive weapon, evidence of the animal’s predatory lifestyle. But how, exactly, would it have been used? Two possibilities spring to mind: either it was capable of slashing at its prey with one foot at a time, as some large ground-dwelling birds such as ostriches and cassowaries do today (this implies that it could have balanced on one foot from time to time); alternatively,  Animatronic dinosaur it may have attacked its prey using a two-footed kick, by jumping on its prey or by grasping its prey in its arms and giving a murderous double-kick - this latter style of fighting is employed by kangaroos when fighting rivals. We are unlikely to be able to decide which of these speculations might be nearest the truth.

 

The long arms and sharply clawed hands would be effective grapples for holding and ripping its prey in either of these prey-capture scenarios and the curious raking motion made possible by the wrist joints enhances their raptorial abilities considerably.  Walking dinosaur costume In addition, the long, whip-like tail may well have served as a cantilever - the equivalent of a tightrope walker’s pole to aid balance when slashing with one foot - or it could have served as a dynamic stabilizer, which would prove useful when chasing fast-moving prey that were capable of changing direction very quickly or when leaping on prey.

 

While this is not an exhaustive analysis of Deinonychus as a living creature, it does provide an outline of some of the reasoning that led Ostrom to conclude that Deinonychus was an athletic, surprisingly well-coordinated, and probably intelligent predatory dinosaur. Lifelike animatronic dinosaur for sale Why should the discovery of this creature be regarded as so important to the field of dinosaur palaeobiology? To answer that question, it is necessary to take a broader view of the dinosaurs as a whole.
