Dinosaurs were not nearly as hard on predators

The answer is that the grasslands and woodlands of the Serengeti are very far from ideal.(animatronic dinosaur) The savannah covered by short grass is poor hunting ground because there isn’t sufficient cover to allow the lions or hyenas to approach their prey. As a consequence, the predators are inefficient and do not catch enough prey to make an ecological difference, so the vegetarian herds grow bigger and bigger. And humans compound the situation. Herdsmen and ranchers kill off predators to protect their livestock. Poachers and pelt hunters kill for the skins. Hordes of tourists insist on harassing the predators during their hours of rest. (dinosaur costume)In consequence, the Serengeti predators never build their populations to full potential. Is it any wonder why the predator-to-prey ratios are so far below the maximum possible with prey multiplying so abundantly and predators multiplying at such a minimum? Clearly, the predator-to-prey ratios of this modern game park are most unreliable guides for any understanding of the past.

 

Most of the habitats frequented by fossil mammals or dinosaurs were not nearly as hard on predators as the Serengeti. The ancient ecosystems were not generally as treeless and, of course, were free of any interference from humans. It would not be surprising therefore to find higher predator-to-prey ratios obtaining in the fossil samples.(dinosaur equipment) In addition, many ancient predators enjoyed the advantage of being well-enough armed to attack successfully even the largest plant-eater. Today’s lions and hyenas are not big enough to kill healthy adult rhinoceroses, elephants, or water buffalo. But that is not typical of the situation during the entire Age of Mammals. Most of the time in the past, the carnivores were large and strong enough to assault the biggest prey; for example, the giant wolf-bear Pliocyon found in Nebraska eight million years ago averaged five to six hundred pounds. (animatronic dinosaur supplier)If it hunted in packs, Pliocyon could have killed elephant-sized prey with ease. In gen eral, the typical mammalian fauna of the past included far more formidable top predators than do any of today’s ecosystems. Since fewer plant-eaters were immune to attack, the top predators would have been more efficient at culling them and building up the pred-ator-to-prey ratio. On balance, these considerations suggest a solution to the paradox presented by the difference between ancient and modern ratios. Warm-blooded predators could achieve ratios as high as 5 percent when climate was favorable, when they were strong enough, and when there were no humans to befoul the sample.
