Predatory dinosaurs have been gone for 650,000 centuries, but ihat does not stop us from painting such pictures of horv they made a living-how they hunted, how they spent their spare time, their social behavior, reproduction, and the like.iWe are able to do so by making deductions based on what we know about their structure and on the fossil records. In describing the life-styles of the predatory dinosaurs, I am going to work from a basic assumption that the dinosaurs were fully warm-blooded in the way birds and mammals are realistic animatronic dinosaur.

 

Let us begin with the one feature that made most predatory dinosaurs what they were-killers-and that is their teeth. (The habits of the toothless predators-ostrich-mimics, oviraptors, walking dinosaur costume and avimimids-are investigated in Part II, page 358). Most typical theropods had long rows of sharp teeth. This tells us that they were predators-for herbivores simply do not have such teeth. The fact that they were predators in turn tells us something less obvious: that theropods enjoyed much more leisure time than do most humans, and spent most of it asleep. This is typical of medium sized and big predators-lions and even house cats for that matter spend up to twenty hours a day napping. Predators, especially those that kill big game, go out and kill something, eat it in one quick sitting, and then sleep it off until they are hungry again. As detailed in Appendix A, big predators can go for days or, in the case of giants, even weeks between meals. This is quite unlike herbivores, which must spend long hours nipping at and chewing large quantities of fodder. realistic dinosaur costume In fact, sleeping when there is nothing else to do has an important advantage. Bedding down helps keep an animal out of sight and out of trouble. This is especially true for small species and the juveniles of big ones, for big predators are very happy to attack and consume smaller predators.
