But whatever amount of time they spentlazing about, predatory dinosaurs were built for those briefer but much more intense and interesting times-when they went off to kill and eat other animals. Killing big animals requires firepower, and in animals such power can only come from muscles. Mammalian carnivores of today have oversized neck muscles which give them tremendous biting power, something our household pets can demonstrate. Feel the neck muscles of a big dog and compare them to your own. Likewise, the heads of most predaceous dinosaurs were packed with powerful jaw-closing muscles, and their neck muscles were well developed, further increasing the available killing power realistic dinosaur costume.

 

An obvious difference between a carnivorous mamm al and a theropod is seen in the form and function of the teeth. Predatory dinosaur teeth were not aruayed in the short sets of molars, canines, and incisors seen in modern cats and dogs. Dogs'big, sharp, conical canines are used to puncture flesh; canids and hyenas like to grab on to various parts of big prey and pull; weasels and cats deliver precision bites to vulnerable areas such as the base of the skull or the throat, and then use their complex slicing molars to cut up the meat.walking dinosaur costume聽The predatory dinosaur's long rows of uniform, curved, flattened, serrated blades were very different, more akin to those of the modern predatory lizard. (The closest mammalian analogues were the extinct sabertoothed cats, which, recent research indicates, used a peculiar pinch-and-slash biting action.2) The key point is that most predaceous dinosaurs were neither grabbers nor precision biters. The long, irregular tooth rows of the theropods were not suitable for precision work, and their bladelike teeth would have tended to slice or cut through the flesh of their prey rather than to hold tight. In fact, the semations, which were on the keels on the front and back edge of the teeth, enhanced this slicing effect. A bit of often-repeated nonsense is that these teeth were as sharp-edged and pointed as steak knives. Actuaily, one can run one's finger hard down the serrations with no adverse effects. But, powered by big jaw and neck muscles, the slicing performance of these tooth rows was potent3. The wounds they inflicted would have bled heavily and readily become infected. life size dinosaur for sale Limb muscles could have been sliced, crippling their prey. Or the belly could have been disemboweled- just as the giant Komodo monitors of modern day Indonesia will cut open the bellies of oxen and deer.
