Predatory dinosaurs exhibited very low ratios

Orthodox paleontologists greet these arguments from predator-to-prey ratios with incredulity. But they make ecological sense.(animatronic dinosaur) Predatory dinosaurs exhibited very low ratios (1 percent or less) in the same sorts of difficult habitats where warm-blooded mammals obtained low ratios. And they achieved higher ratios in more favorable situations, exactly as did the extinct mammals. Most important point of all was that both dinosaur predator-to-prey ratios and fossil and living mammal predator-to-prey ratios averaged far, far lower than those of certifiably cold-blooded reptiles.

 

There is also important independent confirmation to be derived from the evidence from the microstructure of bones discussed in a previous chapter. All the extinct groups whose bone texture indicated fast growth dinosaurs, protomammals, and mammals also had low predator-to-prey ratios. Moreover, my arguments from predator-to-prey ratios caused such controversy that I sought additional supports as well.(walking dinosaur costume) In 1982, it occurred to me that footprints could serve as further proof.

 

It seemed logical that warm-blooded animals would be forced to move around for food at much higher average speeds than their cold-blooded cousins because high metabolism demands a more or less continuous supply of calories, hence a more or less continuous search for them.(dinosaur equipment) If correct, this notion implies that fossil footprints would be good indicators of the number of required calories. Since they usually record unhurried, and not maximum, speeds, fossil footprints should be reliable indicators of the aver-age intensity of foraging.
